The Effects of a Tumor on the Family Members
A tumor that is specifically in the frontal cortex can cause many changes physically and emotionally
which can affect the way you interact with your family. Some of the functions of the frontal lobe are
attention, abstract thought, problem solving, intelligence, creative thought, initiative inhibition,
judgment, mood, major body movements, bowel and bladder control, memory and reasoning
(retrieved from www.ect.org. What this means is that you will not only experience these symptoms
internally but externally as well. Family members may start to see the decline in your health and
become concerned.

Denial involves the rejection of even the possibility that this could be happening. Anger involves
feeling upset at the world, the patient, the Doctor etc.
Acceptance is the emotion that includes excepting the situation and remaining hopeful towards the
future. If some family members are having an especially hard time coping with the news, it might be
wise to seek family therapy.
Someone in the family might volunteer to help during the difficult time. The effects of care giving
can be rewarding and stressful. It is important to remember that one person cannot handle
everything. Other family members and friends can assist with even the smallest situations.
Attempting to take on all the responsibilities can lead to burnout or even anger towards the person
with the illness. As the caregiver, venting can be a form of distressing yourself. Discussing ones
feelings is imperative, you do not even have to speak to a professional, you can just speak to good
friend (retrieved from www.abta.org ). It might be helpful to let them know that they do not have to
make everything better but they just have to listen.

Devil Facial Tumor Disease Analysis
Devil Facial Tumor Disease (DFTD) can be recognized by lumps around the face and neck.
(Evolution.berkeley.edu, 2008),which causes starvation in 12–18 months due to feeding difficulties
and therefore death (Deakin and Belov, 2012) . This fatal disease affects only Tasmanian devils,
marsupial carnivores of Tasmania. Scientists reported that devils may be responding to DFTD by
breeding earlier before the disease kills them, which could help the species survive longer (Hamede,
McCallum and Jones, 2012).
DFTD spreads due to biting between animals during mating or feeding. The cancer cells themselves
are the infective agent, as opposed to a transmissible virus that leads to Tumor formation. in the case
of the devils (Pearse et al., 2012), the genes that could differentiate between own and foreign cells
are so similar between the cancer and host, that the devil's immune system does not identify the

Females used to breed at two years of age began breeding at two years of age and that many devil
females now begin to reproduce at just one year. It could be that DFTD has selected for younger–
breeding females (Deakin et al., 2012). Females with genes for early–breeding would be
advantageous over standard breeding times females , and due to this reproduction difference, the
population may have undergone evolution(McCallum et al., 2009). Alternatively, it could be that the
population genetic makeup have not undergone any changes,but with more food access due to a
reduced devil populations(Evolution.berkeley.edu, 2008), younger females are now able to

Glioma Brain Tumor
On April 14, 2012, my husband was diagnosed with a Glioma Brain Tumor. Even three and a half
years after his diagnosis, I still don't really know much about Gliomas, so I have decided to research
this topic. Gliomas are primary brain tumors, which mean they start in the brain. They are a fairly
common type of brain tumor. These types of tumors originate in the glial cells. Glial cells in the
brain surround and support neurons. Because Gliomas often intermix with normal brain tissue, they
are called intrinsic brain tumors. Gliomas show up in three different types of cells: astrocytes,
oligodendrocytes and ependymal cells. Astrocytomas will be produced by an astrocyte, an
oligodendroglioma will be produced by an oligodendrocyte and epedymomas will be produced by
an ependymal cell. If there is a mixture of these cells, then it is called a mixed ... Show more content

Type, size, grade of glioma, location of glioma, age, and overall health of a patient helps to
determine a treatment. Surgery to remove the glioma is commonly the first step in treatment.
Sometimes, the tumor is small and surrounded by healthy tissue and can be surgically removed.
Other times, gliomas are not easily separated from healthy tissue and are located in or around areas
that cannot be surgically removed. Radiation therapy sometimes follows surgery. Chemotherapy is
another treatment used for gliomas. Chemotherapy is often used with radiation therapy.
Chemotherapy is a type of medication used to kill tumor cells. Targeted drug therapy is also
sometimes used as a treatment of gliomas. Some people also like to use alternative medicine
including, hypnosis, acupuncture, meditation and music therapy.
Information about prognosis for people with gliomas is very hard to find because there are so many
factors to determine. Prognosis is dependent on type of tumor, grade of tumor, size and shape of
tumor, position in the brain, age at diagnosis, and type of

What are Brain Tumors?
Brain Tumour Definition Simply defined, brain tumour is a growth of abnormal cells in your brain.
There are different types of brain tumours – while some brain tumours are noncancerous (benign),
others are cancerous (malignant). Brain tumours that begin from the brain are called primary brain
tumours; and those that begin from other parts of the body and then spread to the brain are known as
secondary or metastatic brain tumours. Symptoms The symptoms of brain tumours vary, depending
on size of tumour, location and rate of growth. However, general symptoms can include: Onset or
change of pattern of headaches More frequent and severe headaches Unexplained seizures, nausea
or vomiting Vision issues such as blurred vision or double vision Loss of sensation in arm or leg
Difficulty in maintaining balance Difficulty in speech Behavioural changes Hearing problems Types
of brain tumours Primary brain tumours Primary brain tumours are those that originate in the brain
or the tissues that surround it, for example, cranial nerves, brain–covering membranes, pineal gland
or pituitary gland. These tumours are a result of mutation that occurs in the DNA of normal cells.
Because of these mutations, the cells grow and divide at an increased rate. Gradually the healthy
cells die while the abnormal cells continue to grow, thrive and gradually form a tumour. Types of

Inoperable Brain Tumors Research Paper
Is There Treatment for Inoperable Brain Tumors? A person has a 0.55–0.7% chance of developing
any type of brain tumor in their lifetime (Mohammadi and Schroeder 1). A brain tumor is a mass of
abnormal cells located somewhere in the brain. Brain tumors can be caused by many different
disorders including Tuberous Sclerosis Complex (TSC). Some tumors caused by this disorder are
inoperable. Inoperable brain tumors can now be treated using new advanced technology.
Technological advances provide new hope for patients who have inoperable brain tumors and TSC.
TSC is a rare genetic disorder that is the source of benign (noncancerous) tumors located in the
brain, heart, kidneys, and other organs (Mayo Clinic Staff). In most cases TSC is diagnosed early in
infancy, but in other cases it is not diagnosed for several years. In certain cases, patients have such
mild signs that the disorder will go undiagnosed. One in six thousand people have been diagnosed
with TSC. Although this is a rare disease, awareness is building and multiple TSC clinics have been
built across the country to assists those with the disorder. TSC is caused by a genetic mutation in the
TSC1 or TSC2 gene. The mutations in these genes cause several lesions in the body to appear. This

Pineal Gland Cell Tumors
tumors are treated but if surgery is not a viable treatment radiation can also be used. Schwannomas
are most commonly non–cancerous and begin in the hearing nerve. The hearing nerve can also be
called the acoustic nerve, 8th cranial nerve, or the vestibulocochlear nerve. For the most part, this
type of tumor is found in between the cerebellum and the pons at an angle. This type of tumor
exhibits slow growth as these tumors slowly grow they move nerve fibers which can cause
complications. Furthermore, they can form in any nerve that is peripheral as long as Schwann cells
are present. If the Schwannomas form in the spinal canal they can form in a dumbbell shape which
can then move in or out of the spinal canal using the nerve root. The main ... Show more content on

Furthermore, Pineal Region tumors don't have to involve the pineal gland The different types of
tumors that truly come from pineal gland cells are mixed pineal tumors, pineoblastoma, and
pineocytoma. The types of tumors that can occur in the pineal region but don't necessarily have
pineal gland cells are germinoma, non– germinoma, dermoid cysts, meningiomas, astrocytomas, and
gangliogliomas. The pineal gland cells come from the pineal gland which is located at the back of
the third ventricle. A ventricle in the brain is a cavity filled with fluid. The pineal gland tumors are
all different like the Pineocytoma is only a grade II tumor that slowly grows while the
Pineoblastoma can be a grade IV aggressive tumor or a grade III intermediate. There is also the
mixed pineal tumors that have unique combinations of different cell types. Symptoms associated
with this type of tumor are mainly due to the cerebrospinal fluid flow being blocked as well as eye
movement being compromised. The main symptoms are vomiting, double vision, and headaches.
Pineal Region tumors are thought to have a connection to chromosomal abnormalities and the main
treatment is radiation therapy and possibly surgery. Additionlly, to help with the diagnosis of this
type of tumor many patient will have to have MRI and CT scans to see the size are

Detection Of Brain Tumor Detection Essay
Abstract–A tumor is the growth in the abnormal tissue of the brain which causes damage to the other
cells necessary for functioning. Detection of brain tumor is a difficult task, as there are various
techniques involved in it. The active imaging resource used for brain tumor detection is Magnetic
Resonance Imaging (MRI). It is necessary to use technique which can give the accurate location and
size of the tumor. There are various algorithms proposed for brain tumor detection, this paper
presents a survey on the various brain tumor detection algorithms. It gives the existing techniques
and what are the advantages and disadvantages of these techniques.
Keywords–Brain tumor, MR Imaging (MRI),segmentation,K–means
I. INTRODUCTION A tumor is a mass of cell that is formed by accumulation of abnormal cells.
The complex brain tumors can be categorized on the basis of their origin, growth pattern and
malignancy. It can be detected as benign or malignant, benign being the non–cancerous and
malignant the cancerous.
The diagnosis of brain tumor is difficult because of the diversity in shape, size and location in the
brain. Medical imaging helps in the detection of tumor, there are various techniques like MRI, CT
scan, Ultrasound and X–ray. We are taking Magnetic Resonance Imaging (MRI) into consideration.
MRI gives high quality images of the body parts and is often used while treating tumors. To detect

Abstract
Ovarian cancer is of significant concern to women because it is both hard to diagnose and
aggressive. As of current, there is a lack of viable in vitro models that accurately model ovarian
cancer tumor metastasis and growth. The purpose of this research is to develop a viable 3D hydrogel
that enables the ovarian cancer cell environment to be effectively modeled in vitro. The goal is to
develop a 3D hydrogel scaffold that properly models the mechanical, physical, and chemical
properties of the in vivo environment. These properties include but are not limited to:
vascularization, cell migration, cytokine signaling, metastasis, and chemosensitivity of cancer cells.
By adequately modeling ovarian cancer metastasis in vitro, the proposed scaffold will allow for
more precise screening of drug efficacy prior to usage in in vivo studies. To quantify whether or not
the model is accurate, mechanical, cytokine signaling, and drug efficacy tests will be carried out and
evaluated to determine if the proposed 3D hydrogel scaffold is suitable as a viable in vitro
representation of ovarian cancer cell environment. Thus, in the long–term, this 3D hydrogel scaffold
can be used in personalized medicine and can determine the drug efficacy on a patient's own cancer
cells as a precursor to chemotherapy treatment.

Brain tumor is a congregation or growth of abnormal cells in the brain. There are many different
types of brain tumors exist. Some brain tumors are benign and some are malignant (cancer). Brain
tumors can start in the brain, or cancer can start in other parts of the body and spread to the brain.
Most benign brain tumors do not contain cancer cells. Usually benign tumors can be removed and
less relapse. The boundary of benign is usually clear, and the cells of benign tumors do not invade
surrounding tissue or metastasize to other parts of the body. However, benign tumors can obstruct
sensitive areas of the brain and cause serious health problems. On the other hand, benign tumors in
other parts of the body, benign brain tumors can sometimes be life–threatening. It can become
malignant, but very rare. Malignant brain tumors contain cancer cells. It's usually heavy and life

Tumors fall into to two main types, benign and malignant. Although they are considerably different
in tissue invasion, their nature that makes them distinct and symptoms, they are also quite similar in
the way they recur in the same location, growth size and their health risks.

The first similarity is that just like malignant tumors, benign tumors can also be quite large. A
common mistake patients often make is confuse benign tumors with malignant tumors because of
the size. Although malignant tumors are usually larger than benign tumors, that alone does not make
the difference. In fact, a benign tumors weighing over a hundred pounds have been removed. An
example of a large benign tumor is a 32–year–old man from Vietnam who survived a 12–hour
operation in which a massive 198–pound benign tumor from his right leg was removed at France–
Vietnam Hospital (FV) on January 5, 2012.2 The second similarity is that both malignant and benign
tumors recur locally, to be more specific, the location where the recurrence of the tumor most likely
happens. To elaborate further, both benign and malignant tumors have the ability to reappear near or
in the same area where the previous tumor was located. For instance, recurrent breast tumors are
tumors that have come back in the same breast or chest wall after the treatment for a period of time
when the tumor couldn't be detected.3 The third and final similarity is the danger both malignant
and benign tumors pose to the health of the patient. Similar

Brain Tumors
Brain tumors are devastating depending on their malignancy and also their propensity to cause
neurological deficits which may cause permanent disability. Malignant brain tumors can occur at all
ages [1–2] and are associated with poor prognosis. Surgery forms the mainstay of treatment for
brain tumors [2–5]. It is well known that significant tumor decompression is associated with a
relatively favourable prognosis [6–10]. An important challenge in brain tumor surgery is the
accurate recognition of the tumor existence and positioning [11]. The tumor positioning has an
unique importance in brain tumor surgery. Tumors in the brain are surrounded by normal brain
tissue. The lesions which are sited within the substance of the brain are called intra–axial tumors.
Those in close proximity of the brain, but displace brain tissue are called extra–axial tumors. Even
extra–axial tumors may invade brain tissue. In both cases, the functioning brain tissue surrounds the
tumor.

Cancerous Brain Tumors
Tumors are an area of swelling in a part of the both that does not always create inflammation. These
tumors are usually created by an irregular growth of the tissue. There are two individual kinds of
tumors, one called malignant, which is cancerous and the other benign, which is noncancerous.
There aren't any environmental factors that can usually cause either one of these tumors. Genetic
disease although, can cause certain tumors that can overpower the genes that stop the formation of
tumors. A genetic disease such as neurofibromatosis type 2 can be a prominent cause of a cancerous
brain tumor.
Malignant tumors are harmful to the body and need immediate action. They have an absence of a
border and metastasize by growing in different parts of the body once they have traveled throughout
the vascular system. ... Show more content on Helpwriting.net ...
However, even benign tumors have a risk of causing damage to the brain through either
compression or infiltration.
A tumor in the brain is dangerous if it starts to compress parts of the brain causing neurological
symptoms. This action can destroy the brain tissue it surrounds or it can block fluid in the brain
from flowing. Although it is not cancerous it can also compress parts of the spinal cord depending
where it is in the brain and can also stop the flow of blood in veins surrounding it.
Some symptoms of brain tumors can be someone experiencing a seizure for the first, usually
occurring in older patients. Because the all areas of the brain are what control the functions of the
body, certain areas where the brain tumor is located may cause gradual speech impairments, or
physical impairments such as difficulty walking. A lesser symptom of brain tumors would be
headaches that can be caused by compression of the tissue which can occur in any age of a patient

Personal Narrative: My Brain Tumor
Recently I discovered that I have brain tumor. My surgery is scheduled in two weeks, unfortunately
this requires an incision in my frontal lobe. This will cause loss of intelligence, personality, and
behavior. I have Fourteen days left with a fully functioning brain, wanting to spend this time doing
what I love made me decide what to do. In this two week period I will focus on family, friends, and
some of my favorite activities. The first five days are going to be spent with my family at Smith
Mountain Lake. Following the time at the lake I will rent a beach house and pack it full of my
longtime friends. Lastly in the final days leading up to my surgery I will be in the mountains doing
what I personally enjoy most. Overall I will be relaxing, ... Show more content on Helpwriting.net ...
I plan on setting out on a four day fishing, backpacking trip combination, If possible I would like to
go with my dad and my brothers like in years past. Our morning's would be spent trout fishing along
the Elk River as the day progressed we would hike to the next fishing hole. Fresh trout cooked over
an open fire is my favorite meal, and will be dinner while camping. As the day until surgery grows
near it will be hard not to become overwhelmed with anxiety. For this reason I decided to be isolated
in the woods it gives me a chance to be at peace, think, and admire the natural beauty that we're
separated from in everyday

Types Of Tumor Affects The Brain
Abstract:
Brain is one of the vital organ in human body, it has an extensive capillary network which is highly
vascularized. The brain capillary endothelial cells (BCECs), astrocytes, pericytes and neuron forms
the blood brain barrier (BBB) [1]. There are several types of tumor affects the brain, one such type
of tumor is Glioblastoma multiforme (GBM). GBM is the most frequent and aggressive form of
primary tumor found in central nervous system, the world health organization (WHO) defined GBM
as grade IV astrocytoma [2]. Therefore, this urge us to propose a novel technique to treat GBM.
Carrier– Graphene oxide xxxxxxxxxxx, silica nanocapsules, xxxxxxxxxxx, drugs– Doxorubicin
XXXXXXXXXXXXXX, tetrandrine XXXXXXXXXXXXXXXXX, targeting ligands –

And then test for characterization, invitro and invivo for synthesized nanocomplex.
Aim:
The overall aim of this proposal is to synthesis a biocompatible nanocomplex which as an ability to
pass through the BBB and specifically to treat GBM by sustained drug release. Then, to study the
synergistic reinforced effect of two drugs and their resistance against fast clearance. Herein, we
hypothesis, that our synthesized nanocomplex will have increased bioavailability of drugs, increased
specificity for BBB and GBM, reduced drug side effects and finally, has targeted and sustained drug
release.
As illustrated in figure 1 the synthesized nanocomplex

Circulating Tumor Cells Case Study
Circulating tumor cells (CTCs), represent tumor cells that contain a heterogeneous population of
cells, including apoptotic tumor and viable tumor cells that have cast off into the circulation or
lymphatic vessels from a primary or metastatic tumor and are transported around the body by
undergoing phenotypic changes that are accompanied by a process called as epithelial–mesenchymal
transition (EMT) [69–73]. Evidence now suggests that the tumors has ability to make their own
blood vessels when they reach the size of 1–2 mm3 by inducing angiogenesis or through
vasculogenic mimicry, the blood vessels composed of endothelial cells and tumor cells. However,
vasculogenic mimicry forms blood vessels without endothelial cells. In fact, they are a ... Show

However, it is not necessarily always associated with metastasis, as only 0.01% of CTCs takes part
in metastasis [97, 99, 100]. Moreover, highly sensitive, single cell investigation showed marked
heterogeneity of individual CTCs for protein expression and localization, and the CTCs reflected the
character of both the primary biopsy and the transformations seen in the metastatic sites [101, 102],
which corresponds with the evidence of "seed and soil" hypothesis [103–105].
Amassing proof has demonstrated that CTCs can be utilized as a biomarker to non–invasively
supervise cancer progression and provide direction to monitor the treatment [106–108]. The
American Society of Clinical Oncology (ASCO) approved CTCs as a tumor marker for breast
cancer in 2007 [109, 110].
Nevertheless, CTCs detection, identification, enumeration and molecular characterization are very
challenging. Since, CTCs are uncommon in peripheral blood of patients (that is, 1–100 CTCs among
billions of normal cells) with a half–life between 1 to 2.4 hours and due to its fragile nature it tends
to degrade when collected in standard blood collecting tubes [111–116].
CTCs being a heterogeneous population of cells, CTCs can be positively or negatively enriched on
the basis of: 1. Physical characteristics and 2. Immunologic or biological characteristics. Physical
features include; cell diameter >15 μm, nuclear–cytoplasmic ratio >0.8,

Biography Of Jeffrey Leonard Resected A Brain Tumor
On December 23, 2014, neurosurgeon Jeffrey Leonard resected a brain tumor in a ten year old girl
that was previously thought to be inoperable. Although it took two operations, due to modern
technology and education Dr. Leonard was successful. The girl fully recovered from surgery and
was awake and responsive the next morning. Modern surgeons' knowledge of the human brain has
evolved immensely through the ages. The first brain surgeons did not have anywhere near the
knowledge that we possess today, but it is because of them that the current treatment of neurological
problems is so advanced. Doctors can now perform advanced procedures such as the resection of
tumors and clipping of aneurysms all while a patient is numbed and unconscious when previously
treatment was a painful shot in the dark. Neurosurgery has evolved not only through extensive
research of anatomy and a change in religious perspective, but came hand in hand with the
development of anesthetics and the world's major advancements in radiology and imaging.
Neurosurgery is set apart from every other field because it pertains to the most important part of the
body: the brain. If a person's entire body works perfectly with the exclusion of the brain, that person
will still never be able to function normally. There is a wide variety of neurological defects that can
arise in any one of us including aneurysms, tumors, nerve damage, and strokes. (__) The sheer
fragility of our minds demands highly skilled surgeons to fix

Brain Tumors: A Case Study
In this world, there is no telling when a situation will come across a person that will change the way
they live forever. Life can be drastically altered in the blink of an eye with no sign or warning. My
uncle can be used as a testament to this very fact. Rick Snyder, my uncle, was diagnosed with a
brain tumor a year after I was born. This 32–year–old father, son, and relative, received information
that would change the way he lived for the remainder of his life. At the time, I was so young and did
not quite understand the facts of the situation. I was never educated on brain tumors and what they
mean for the health of a person. I turned to research to develop an understanding on how such a
tragic thing could happen to a loved one. A main ... Show more content on Helpwriting.net ...
This was not easy for his children, wife, and the rest of the family to experience but for his needs,
we needed to be strong, caring, loving, and supportive. Universally, treatment for brain tumors is a
combination of different medications as well as radiation therapy (Kabitha et al. 1169). With being
so weak, his need for transportation to treatment increased as well. It was not easy for his wife
because they also had 4 children. As a result of this, different family members, including my mother,
would help get him where he needed to be. It also needs to be remembered that my uncle still had a
life to live. From the article, "Supporting Adults With A Brain Tumor", written by Polly Newton, it
states, "a clinical nurse specialist will work with everyone involved to ensure a person living with a
brain tumor has the best supportive care at home" (Newton 24). This was what our family attempted
to provide as much as possible. My uncle still needed love from the people around him. We
attempted to care and provide as much normalcy as humanly possible. This was also meant for his
wife and children as well because it had impacted their lives in a negative

Malignant Brain Tumors
Malignant gliomas are the most common type of primary brain tumors. As already shown in the
Central Brain Tumor Registry of the United States (CBTRUS) report from 1998 – 2002, gliomas
account for approximately 80 % of all malignant brain tumors and at least 30 % of all brain and
CNS neoplasms (Ostrom et al., 2014). A number of putative risk factors that have been associated
with brain tumors have been discussed. However, there is no clear cause for brain and CNS tumors.
Less that 1 % are linked to lifestyle or environmental factors (Parkin, Boyd, & Walker, 2011). The
only exposure that has been shown to affect glioma risk is ionizing radiation and has been classified
as a cause by the International Agency for Research on Cancer (IARC) (Cogliano ... Show more

About 22,400 gliomas are diagnosed each year in the U.S. of which approximately 12,075 are
glioblastomas. The incidence rate is 3,19 per 100,000 persons per year and rises with increasing age.
The median age of diagnosis is 64 years and has been reported to be higher in men compared to
women (Ostrom et al., 2013).
Like others, glioblastomas can develop either de novo as primary GBM or through the progression
of lower grade astrocytoma (secondary GBM) (Peiffer & Kleihues, 1999). With about 90 %, primary
GBM account for the vast majority. The two types are hardly distinguishable from a histological
point of view, but show differences concerning their genetic and epigenetic profiles. With regard to
this, primary glioblastomas are characterized by EGFR amplification and PTEN mutations whereas
secondary GBM show genetic alterations in TP53 for instance (Ohgaki & Kleihues, 2007, 2013). In
addition, mutations in isocitrate dehydrogenase (IDH) 1 are claimed to be frequent in secondary
glioblastoma, thus used to be a genetic marker for these (Ohgaki & Kleihues, 2013). Furthermore
GBM can also be classified into four different subtypes on the basis of gene expression. These
include the classical, mesenchymal, neural and proneural

BR200 Section 01
Brain Cancer Treatment
Abstract:
Brain cancer is the formation of a tumor or intracranial neoplasm abnormalities in the brain. The two
main types of tumors are malignant or cancerous tumors and benign tumors. The spreading of
cancer to other parts of the body is called metastasis. Detection of brain cancer is typically done
using magnetic resonance imaging (MRI) and confirmed by biopsy. The class of the tumor falls into
different categories and treatment is determined by the severity of the tumor. Although the cause of
brain cancer is still mostly a mystery there are several risk factors that increase your chance of
developing brain cancer: a hereditary condition known as neurofibromatosis, chemical exposure,
Epstein–Barr virus and ionizing radiation. Although not proven it is believed that talking on the
phone may increase the chances of brain cancer. Brain tumors are treated based on their size,
location, type and severity of the tumor. Typically the tumor is removed in surgery and then the
patient goes through radiation treatment. Early detection of a tumor greatly increases the odds that a
patient will recover. The radiation kills cancerous cells at the same time it kills healthy cells.
Because the healthy cells are also dying the effects off therapy are dangerous. The patients
experience many side effects. A new treatment is being tested where nanoparticles are filled with
genes for an enzyme that turns a compound into a potent killer

Spreading Tumor Cell (CTC)
History of CTC
It has been long accepted that the spread of cancer to multiple organs occurs as a result of cancers
cells traveling from the primary site to the distant sites where they colonize and form a secondary
tumor. Logic dictates that the circulatory system holds the greatest potential to provide passage for
these cells to travel to distant sites. Once these cancer cells have gained access into the circulatory
system, they are referred to as circulating tumor cell (CTC).It has been a tough challenge to
effectively capture these culprits in the act. Large in part due to the inability of the technology of the
past, but with the present day breakthroughs in the fabrication of both biological and synthetic
products, a number of technologies ... Show more content on Helpwriting.net ...
While it seems like this burgeoning field has only recently blossomed, its roots date back as far as
1869, with the first reported description of CTCs by Thomas Ashworth (Ashworth, 1869). After a
sparse trail of publications, early reports on methods for detecting CTCs via filtration (Salgado et
al., 1959) and sedimentation (Alexander and Spriggs, 1960) emerged nearly 100 years later. Perhaps
the most commonly used technique for detection today, immunomagnetic separation, was not
reported until 1998 (Racila et al., 1998). In addition to introducing a new detection method, Racila
et al. also demonstrated that CTCs exist early in disease and correlate with disease progression e
providing a new perspective on the potential role of CTCs in modern cancer research and therapy.
Today, researchers look to profiling components, including CTCs, in serial blood draws (liquid
biopsy) to transform the current landscape of cancer therapy by i) determining patient prognosis, ii)
monitoring tumor recurrence and therapeutic responses in real–time, iii) identifying new therapeutic
targets, iv) elucidating drug resistance mechanisms, and v) improving our current understanding of
tumor progression and metastatic disease. Multiple studies have demonstrated that elevated CTC
counts indicate a poor prognosis for metastatic breast, prostate, colorectal, and lung cancer patients
(Cristofanilli et al., 2005; Smerage et al., 2014; de Bono et al., 2008; Cohen et al., 2008; Miller et
al., 2010; Krebs et al.,

Protein Based Ligands For Tumor Targeting
In addition to peptides, protein–based ligands such as Affibody proteins have been utilized for tumor
targeting. Anti–epidermal growth factor receptor (EGFR) Affibody protein (e.g., Ac–Cys–
ZEGFR:1907, amino acid sequence: Ac–
CVDNKFNKEMWAAWEEIRNLPNLNGWQMTAFIASLVDDPSQSANLLAEAKKLNDAQAPK–
NH2) is used to target EGFR that is overexpressed in a wide variety of human tumors. Cheng and
co–workers used anti–EGFR Affibody protein as tumor–targeting ligand on 64Cu–Au–IO
nanoparticles (PET component: 64Cu, MRI component: iron oxide, specific for EGFR) surface.[63]
In their work, A431 tumor cells were subcutaneously implanted in the right shoulders of nude mice;
and 64Cu–NOTA–Au–IONP–Affibody nanoparticles were administered via tail vain injection.
Rather low resolution PET image showed that these nanoparticles were taken by EGFR positive
A431 (human epithelial carcinoma cell line) cells reaching 4.6% ID/g at 24 h after injection,
significantly higher than that obtained from the blocking experiment (1.9% ID/g) indicating the
specificity of the probe. This difference in % ID/g values corroborated with 44% drop in MRI signal
intensity that was observed for the tumor. In this study, the use of an Affibody protein as ligand for
EGFR–expressing tumor in small animals was demonstrated to be successful; however, the benefit
of multimodality was not demonstrated. The unique chemistry of this dumbbell–shaped Au–IO
nanoprobe could pave the way for targeted drug delivery into EGFR–expressing tumors

How To Classify Tumors
When it comes to systematic classification of tumors, there is more than one adopted scheme. Some
classification schemes are based on the site of origin of the tumor i.e. the cell or tissue from which a
tumor arises, some on their microscopic appearance while others on the genetic defects found in
their cells. However, none of these adopted schemes are followed with rigid logic or consistency and
there are present a number of exceptions to them. These classification schemes help categorize
tumors keeping in mind their characteristic clinical behaviour, such as prognosis, and their response
to therapy.
The classification scheme based on site and tissue type aids in this way that it identifies tumor and
determines the course of treatment to ... Show more content on Helpwriting.net ...
A prefix indicates the predominant cell type in the tumor which is usually followed by the site of
origin. For instance, adenocarcinoma of the lung designates a malignant epithilial tumor arising
from the lung. Here, the site of origin not only plays a crucial role in the classification but also
determines the manner in which a tumor will grow, how fast it will give rise to clinical symptoms
and how early it may be diagnosed. In case of malignant tumors of the blood–forming tissue, the
suffix–emia (which is Greek for blood) is used. Therefore, a cancerous proliferation of the white
blood cells is referred to as leukemia. The suffix–oma, which more properly designates the benign
tumors, is also used to denote malignant tumors in some cases such as that of lymphoma in which
the cancerous tumors arise in the lymphoid organs (spleen, lymph glands, thymus) and seminoma in
which the malignant tumor arises from the germ cells of the testis. Polypoid cancer refers to a
malignant tumor which gives rise to a mass that projects into the lumen. In some cases, a tumor may
even be named after the physician who first described it. The naming of the malignant lymphoma as
Hodgkin disease after the English physician Thomas Hodgkin, Burkitt lymphoma after the British
surgeon Denis Parsons Burkitt, Ewing sarcoma of bone after James Ewing are some such

basis of: 1. Physical characteristics (that is, cell diameter >15 μm, nuclear–cytoplasmic ratio >0.8,
electric charges, deformability, the hyperchromatic nuclei, sunken

Tumor Heterogeneity
Genetic and phenotypic variation is observed between tumors of different tissue and cell types
which mainly due to tumor heterogeneity. Heterogeneity is therefore as an important feature of
malignant tumor in diverse genetic backgrounds, pathological patterns, differentiation stages,
genetic mutation spectrum, transcriptomics and proteomics gene expression profile, et al. It
indicates the high complexity and diversity in cancer progression. Tumor heterogeneity and drug
resistance are great challenges for precision oncology and are taken account for the process of
research and development of new diagnostic methods and further antitumor agents. Tumor
heterogeneity is an important prognostic factor which could be manifested with medical imaging.

Benign Tumors
Benign cell is used to describe both medical conditions tumors an usually refers to a process that's
not especially dangerous. For instance uterine fibroid are common benign tumors. Benign is not
cancerous, will not cause death. There are different types of benign tumors the most frequent tumor
in women is perimenopausal. The benign tumor can be deadly if it grows in an enclosed space such
as the skull, or in regions of the body where their presence can damage vital organs they can be
dangerous.
Malignant tumors are cancerous cells that can spread to other regions of the body. Depending on
what type of cancer cell it is some can be treated with radiation, chemo therapy, they can grow in
size and metastasize to other areas. We can do

Famous Tumor Markers
Tumor marker are substances that are produced by cancer to make a tumor found in your blood.
They are produced in a much higher cancer level. It could be found in blood, urine, tumor tissues or
other tissues if the patient have cancer. Tumor markers are proteins. Most are associated with one
cancer.
There is a bone test. A bone test when they determine if your bones are damaged either from cancer
or some other cause. The scan will detect if you have cancer in your bones. People don't usually
have to prepare for a bone test. You can drink and eat regularly. But you have to tell your doctor
what medicine you're taking.
There is a breast cancer test. A breast cancer MRI can help you detect early breast cancer. The test
usually detects the

Essay on Salivary Gland Tumors
INTRODUCTION: Salivary gland tumors are a morphologically diverse group of neoplasms, which
may present considerable diagnostic and management challenges for the pathologist and surgeon.
Salivary gland tumors are rare with an overall incidence in the western world of about 2.5 to 3.0 per
100,000 per year. About 80% of all lesions are benign; hence salivary malignancies are particularly
rare, comprising less than 0.5% of all malignancies and about 5% of cancers in the head and neck.
(1) Most of the studies on salivary gland tumors are in reference to western population and to the
best of our knowledge this study is the first of its kind in Indian population. In this study, salivary
gland neoplasms were retrospectively studied ... Show more content on Helpwriting.net ...
Immunohistochemical analysis for smooth muscle actin (SMA) was done and the intensity of
staining and staining location were considered. RESULTS: A total of 1855 biopsy specimens were
accessioned at our biopsy services during the study period (2002 – 2006). In this period, 37 cases
were salivary gland neoplasms accounting to 1.99% of all biopsy specimens accessioned. Of 37
cases, 11 were benign neoplasms (29.72%) and 26 were malignant (70.27%). The common tumors
overall was Pleomorphic adenoma (PA) and Muco–epidermoid carcinoma (MEC) (Table 1). Of 37
cases, 9 cases occurred in major salivary glands, with eight occurrences in the parotid region – 1 PA,
1 Adenolymphoma & 6 Acinic cell adenocarcinoma (AcADCC) and one in submandibular region– 1
Polymorphous low grade adenocarcinoma (PLGA). Of 37 cases, 28 cases occurred in minor salivary
glands, with palate being the most commonly affected site by both benign (63.63%) and malignant
tumors (58%). Males represented 54% of the affected patients, and certain tumors showed a strong
male predilection, like MEC (6/10), PLGA (2/2), Adenoid cystic carcinoma (ACC) (5/8),
Adenolymphoma (1/1); in contrast, some tumors such as PA (7/10), Acinic cell carcinoma (4/6)
showed a female predilection. The mean age for malignant tumors in females (40.6 years) was lower
than

Pancreatic Tumors: A Case Study
There is another classification of pancreatic tumor help in decision making of management. This
classification depends on the possibility of surgical removal of the tumor: in this way, tumors are
judged to be "resectable", "borderline resectable" or "unresectable" (American Cancer Society,
2014).
AJCC stages I and II defines the disease without spread to large blood vessels or distant organs such
as the liver or lungs with possibility of surgical resection of the tumor (Bond–Smith et al., 2012).
The AJCC staging system allows distinction between stage III tumors that are judged to be
"borderline resectable" (where surgery is technically feasible because the celiac axis and superior
mesenteric artery are still free) and those that are "unresectable" ... Show more content on

Badger et al., in 126 surgically resected pancreatic cancer patients, showed that lymphatic vascular
and perineural invasion, together with the grading, are important predictors of outcome and their
presence is associated with a reduced survival (Badger et al ., 2010).
In particular, perineural invasion has a crucial role in the local recurrence of disease after surgery.
Perineural space is known to be an important route of pancreatic cancer invasion. Pancreatic cancer
cells invade the neural plexus distributed in pancreatic parenchyma and spread through perineural
space to reach extra–pancreatic nerves, such as the celiac plexus or the supra–mesenteric artery
plexus. Cancer cell invasion into the neural plexus often results in non–curative resection and,
therefore, retroperitoneal recurrence (Kenmotsu, 1990, Kameda et al., 1990).
(d) CA19–9, CEA: has also importance in the prognosis of cancer pancreas (Blumenthal et al.,
2005). Studies showed that patients who present a significant increase of CA19–9 at the time of
diagnosis or onset of chemotherapy, have a reduced survival compared to those in which the marker
is normal (Maisey et al.,

Tumors And Tumors
Tumors and tumor–like lesions usually been discussed in a large category, because their appearances
sometimes are similar and make differential diagnosis extremely difficult. But tumors are non–
neoplastic lesions, while tumor–like lesions are not, therefore, treatment and prognosis of these two
groups of disorders are usually different. The incidences of tumors and tumor–like lesions have big
differences in literature, this may due to the classification of benign, malignant and non–neoplastic
conditions usually overlap (Casadei et al., 2013; Pluot, 2009). In addition, some cases are

Imaging appearance of patellar GCTs is usually similar to the lesions occur in other sites(Singh et
al., 2009), and they are characterized in radiographs and CT as eccentric soap bubble–like lytic bone
lesions, without sclerotic margins or mineralization, transition zone to normal bone is narrow(Pluot,
2009). Pathologic fracture and septations are frequently reported, and the septations are usually thin
and may extend throughout the tumor(Singh et al., 2009). MRI provides more details of the
extraosseous extension cortical penetration and associated soft–tissue mass than X–ray and CT
(Singh et al., 2009). GCTs is typically demonstrated as low to intermediate intensity on T1–
weighted images and intermediate to high signal intensity on T2–weighted MRI(Pluot, 2009). Fluid
to fluid level indicates blood–filled cavities of secondary ABC formation, and areas of low signal
intensity suggest haemosiderin depositions(Pluot, 2009). Completely resection the tumor and
patellectomy are the main treatment of GCT in the patella. Postoperative follow–up is necessary to
detect local recurrence and remote metastasize (Malhotra, Sharma, Kumar, & Nataraj, 2010).

Cancerous Tumor Research Papers
TUMOR
A tumor, also known as a neoplasm, is an abnormal mass of tissue which may be solid or fluid–
filled. A tumor does not mean cancer – tumors can be benign (not cancerous), pre–malignant (pre–
cancerous), or malignant (cancerous). There are many different types of tumors and a variety of
names for them – their names usually reflect their shape and the kind of tissue they appear in. A
tumor is a kind of lump or swelling, it does not necessarily pose a health threat. Tumor are not
necessarily cancerous, Benign tumors cannot spread, fibroids are benign tumors that grow on
fibrous or connective tissue, lipomas consist of adipose tissue, a premalignant tumor is one that is
