I would refer a family friend or colleague to the American Cancer Society (ACS) website where a huge selection of support programs is offered
throughout treatment and recovery (ACS, 2017c). There is an entire section dedicated to assisting with finding resources in whatever area someone is
in or near and different programs from which to choose (ACS, 2017c). Visitors of the website can also filter their search based on an array of different
choices ranging from, but not limited to, advocacy, assistance, information, referral, supplies, support groups, and transportation (ACS, 2017c). The

Right now, cancer is one of the most feared diseases in the world. In the early 1990s almost 6 million new cancer cases developed and more than 4
million deaths from cancers occurred. Also more than one–fifth of all deaths were caused by cancer and it has been predicted, by the American Cancer
Society, that about 33% of Americans will eventually develop this disease. This is a huge disease that is killing people all over the world. The field of
cancer study is called Oncology. The government has spent billions ofdollars on research of this fatal disease. Cancer is the most aggressive disease of

Any agent that causes cancer is called a carcinogen. Carcinogens are generally classified into three groups– chemical, biological, and physical.
Chemicals that cause cancer have many different molecular structures and can be just about any type of chemical. Some substances that cause cancer
are complex chemicals and gases, certain metals, drugs, hormones, substances in molds and plants and many more. Many nitrosamines, or simple
organic oxides of nitrogen, are carcinogenic. That and hydrocarbons are carcinogens in cigarette smoke and increase the risk of lung cancer. Also
another chemical gas, vinyl chloride, gas has been found to be an agent of sarcoma of the blood vessels in the liver. Many drugs as well as alkylating
agents used to treat cancer are carcinogenic. Even though these chemicals break the DNA of cancerous cells, which kills them, it also induces cancer in
normal cells. Some hormones created in humans can also cause cancer.
High levels of estrogen, which is marked as a female hormone, can increase the chances of getting a cancer of the uterus (in women). Aflatoxin B is
a substance produced by the mold Aspergillus that causes a number of cancer, but generally liver cancer. Many carcinogens have not been discovered
but research is being done to discover other carcinogens to keep people aware and safe. There are also many different biological agents which cause
cancers. The most

Skin Cancer
What is it and how to prevent it
Skin cancer is the most prevalent of all cancers. There are three types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and malignant
melanoma. In this presentation I plan to discuss a little about each of these cases as well as tell ways to prevent and treat them. The first most common
skin cancer is basal cell carcinoma. This cancer develops in the basal or bottom layer of the epidermis, which is the top layer of the skin. The cause
of this cancer is a gene called patched or PTC, which helps to control cell growth and development. If this gene is missing, defective, or damaged by
ultra violet radiation, unrestrained cell proliferation may result. Basal cell...show more content...
About 48,000 new cases are diagnosed annually in the United States. About 7,700 people die from this disease each year. Melanoma may
suddenly appear without warning but it may also begin in or near a mole or other dark spots in the skin. The most important step you can make is
to have any changing mole examined by a dermatologist so that any early melanoma can be removed while still in the curable stage. Heredity can
also play a role since a person has an increased chance of developing melanoma if a family member has had melanoma. Warning signs of melanoma
include: changes in the surface of a mole, scaliness, oozing, bleeding or the appearance of a new bump, spread of pigment from the border into
surrounding skin, and change in sensation including itchiness, tenderness, or pain. In conclusion, skin cancer is a danger to all whom work or dwell in
the sun while at its peak. To prevent skin cancer of any kind, the Skin Cancer Foundation recommends that people avoid the sun at its peak, which is
from10am–4pm. Use sunscreen regularly. Any skin changes or abnormalities should be reported to a physician. In the event that you do develop skin
cancer, there are surgical methods used to remove cancerous tissue. In some cases tissue is destroyed through the application of intense cold or
cryosurgery. In advanced cases, surgical removal of tissue along with radiation, chemotherapy, or both may be

Cancer Essay
Cancer
Cancer is a disease in which cells grow out of control and invade, erode, and destroy normal tissue. Damaged genes cause this development of cancer.
These damaged genes are often a factor caused by such things such as the environment, and can be influenced by inherited factors. As the very early
damaged cells divide they can evolve into a malignant cell population, and lose the control mechanism that govern normal cell division. These
malignant cells can then go on to form solid tumours that start to destroy normal tissue. These can then spread to other parts of the body by releasing
these tumour cells. Once these cancer cells spread, they grow in other parts of the body and then form...show more content...
These are known as mutagens. These carcinogens can cause errors, duplication or rearrangement in DNA sequences that contribute to the progression
of cancer. An example of a carcinogen is tobacco. Tobacco smoke contains at least twenty carcinogens, which are known to cause lung cancer.
Age can be a factor when asked what causes cancer. This is because cancer becomes more common as we get older. 85% of cancers are diagnosed in
patients over fifty–five. This is because as we get older we become more susceptible to some types of carcinogens. Age is also a cause as it takes a
long time for a cell to become cancerous, as there has to be a number of changes to the genes within a cell, before it turns into a cancerous cell.
Therefore the longer we live; the more time there is for us to become susceptible to these mistakes in our genes.
Our genetics are also another cause of cancer. If we are born with one of these genetic mutations, which can cause cancer, we are said to be genetically
predipositional. This is known as many of the genes that control cell growth, and DNA repair are associated with inherited cancer susceptibility. The
genes, which are susceptible to leading to cancerous mutations, are called proto–oncogenes. They are called oncogens as the word "onco" means
cancer. An example of this is the faulty genes, BRCA1 and BRCA2. If a woman carries one of these genes, she is

Causes of Cancer
Cancer is a non–inflammatory disease, which can be defined as abnormal cell divisions and growth in a specific part of the living body. There are
many different types of cancer, which are classified and named according to the type of affected cells. In normal cases, each cell has controllable
limited growth and divisions in addition to limited life span. When this life span completed, the cell will die. In cancer cell (abnormal cell), the cell
growth become out of control with unlimited divisions, and this cell does not die. The continuous abnormal division of cancerous cell will form
cancer mass. The cancerous cell can invade the neighbor cells or tissues in the body, or can transfer through the blood vessels or the...show more

The inheritance of gene defects increases the chance of cancer formation in the future.
2.The Age
There is a positive relationship between age and cancer formation. The old people are more susceptible to have cancer than the young people because
they have weak immune systems, and they also have been exposing to cancer–causing agents more than the young people and children. Although the
age and cancer are positively related, it is not necessarily that each old person will have cancer.
3.Life styles and bad habits
There are many factors that could be included in bad life styles and habits, and may cause cancer. The most harmful agents are tobacco and alcohol.
There is no doubt that tobacco–smoking and alcohol–drinking people may have cancer during their life. Some specific cancer types are mostly related
to tobacco and alcohol consumption (such as mouth, esophagus, stomach, lung, liver, and kidney cancer), but this doesn't mean that tobacco and
alcohol cause just these types of cancer, or these types of cancer occur as a result of the consumption of these materials. Obesity and exercises are
another risk factors that may lead to cancer. People who are obese or do not exercise become more susceptible to cancer because these factors can
affect the immune and the endocrine systems.

Ultimately, it may involve judgments about the use or restraint of use of costly resources despite little chance of benefit [8]. Deciding when to
discontinue chemotherapy is often challenging, however, given limited data on whether chemotherapy is helpful or harmful in the final months of life.
This study to my knowledge is the first to describe the pattern of PCT utilization and continuation until the end of life in
King Saudi Arabia. This study revealed that, among the patients with advanced cancer; 29.5% received LM–PCT. Multiple studies reported the increase
of PCT practice. In Italy, within 30 days of death, 23% of patients with incurable cancer received PCT [6]. This was within the range of previous
published results, 18–33% [9–11].
Among the identified patients who had been received PCT,21.8% was commenced in the last week, 22.6% in the last2 weeks and 55.6% in the last 4
weeks of life, compared with
8% in the Australian population and 18.5% in the North
America population in the last 2 weeks of life [12].
During the study period, we observed a progressive increase in the number of LM–PCT; 19 patients (15.3%) in 2011, 35 patients (28.2%) in 2012, 46
patients (37.1%) in 2013 and 24 patients (19.4%) in first 4 months of 2014 (till April 2014).
The possible explanations to account for the higher rate and progressive increase in futile chemotherapy in our country include, limited access to

Outline On Cancer Research Paper
Cancer Cancer is a disease that can change the life of a person no matter their age or nationality. Cancer can range from being life threatening to a
low risk of death. Cancer cells are cells that do not follow the regular cell growth and division pattern. They go through cell division and produce
rapidly. Cancer cells differ from regulating cells in the body because normal cells eventually die. Cancer cells, on the other hand, do not die when
they should causing it to be very hard to cure cancer in your body. One thing I learned in researching cancer is that in order for cancer to appear in
our body it has to avoid being detected by our immune system. The cancer cells have to avoid being detected by the immune system because if they
are detected the immune system will try and fight off the abnormality. If your immune system does not detect the abnormality in cells, the cancer cells
will grow and reproduce causing cancer to spread rapidly. The cancer cells that are not detected they can create colonies and spread rapidly. There are
many ways that you can get cancer. You can get cancer from smoking, sunlight, your diet, mold, viruses, and inheritance. Out of those factors, the most
common cause of cancer today is smoking. All cancers are genetic because they are caused by the mutations that happen to the gene. Some common

The tumor needs blood flow to survive so they try and attract the blood vessels to grow into the tumor to keep it alive. The blood vessels usually
don't grow very far into the tumor causing it to lack the nutrients of the blood. The tumor gets oxygen and glucose from the bloodstream. The tumors
also have to figure out how to get rid of wastes and carbon dioxide. So in all the blood vessels are very important to the cancer cells because the blood
stream brings out all the toxic waste for the tumor so that it doesn't

There are many different type of cancers, there are also many different types of treatments. One of the most known types of treatments would be
chemotherapy. Chemotherapy can be used for a wide range of different types of cancers and diseases, and each of the different types of cancers or
diseases require a different group, and sometimes order, of chemicals to properly treat the cancer or disease. These chemicals include: Alkylating agents,
Antimetabolites, Anthracyclines, Topoisomerase inhibitors, mitotic inhibitors, corticosteroids, and more. Each of these drugs previously listed have its
own cancer type(s) or disease(s) that it can assist in treating. Some of these cancers include: Leukemia, Lymphoma, Hodgkin disease, multiple...show

According to the oral cancer foundation, "Chemotherapy is the use of chemicals to destroy cancer cells. Chemotherapy works by interfering with the
cancer cell's ability to grow. It is one of the three main methods utilized to treat cancer." With cancer being a potentially fatal disease it is important
to diagnose it as soon as possible. the oncologist have to study the chemicals used so that they can determine what chemicals will treat the cancer
or disease the best and what chemicals can be mixed together without any major side effects. The drugs can be divided into groups based on how
they work, their chemical structure, and their relationship to other drugs. Before chemotherapy the survival rate of people with cancer was lower.
Cancer cannot be eliminated by natural resources; however, there is a way for someone who has had it to prevent it from coming back. It has been
proven that if you get cancer it is likely to come back between 6 to 10 times. You can prevent this by eating healthy. By eating healthy you strengthen
your immune system allowing it to be able to fight and destroy the cancer cells living in your body. Chemotherapy has helped society by helping save
millions, maybe even billions of peoples' lives. In my opinion I think that scientist, chemist, and oncologist

Introduction and Conclusion to Cancer
1.What Is Cancer?
CANCER, a 6 letter word that makes our world upside down.
Cancer is not just one disease, but a large group of almost 100 diseases. Its two main characteristics are uncontrolled growth of the cells in the human
body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled, cancer can result in death.
2.How does cancer occur? The body is made up of trillions of living cells. These cells grow, divide, and die in an orderly fashion. This process is a
tightly regulated one that is controlled by the DNA machinery within the cell. When a person is a baby or a child or within his or her mother's womb,
cells divide rapidly to allow for growth. After the person...show more content...
* Likelihood of recurrence – Benign tumors seldom occur after surgery, whereas malignant tumors recur much more commonly. Surgery to remove a
malignant tumor is more difficult than surgery for a benign tumor. Using the fingerlike analogy above, it is much easier to remove a tumor that has a
clear fibrous boundary than a tumor that has penetrated nearby tissues with these fingerlike projections. If cells are left over from these fingers, the
tumor is more likely to come back. * Systemic effects – Malignant tumors are more likely to have systemic, or total body, effects than benign tumors.
Due to the nature of these tumors, symptoms such as fatigue andweight loss are common. Several types of malignant tumors also secrete substances
that cause effects on the body beyond those caused by the original tumor. An example of this is the paraneoplastic syndrome caused by some cancers,
resulting in a wide array of physical symptoms from hypercalcemia (an elevation of calcium in the blood) to Cushing's syndrome(which in turn causes
symptoms such as rounding of the face, stretch marks and weakened bones). * Death toll – Benign tumors cause around 13,000 deaths per year in the
United States. The number of deaths that can be blamed on malignant (cancerous) tumors is over 575,000.

The cancer starts in the inner layer and continues to grow outward. There are two types of esophageal cancer. The first one is Squamous Cell Carcinoma
. The second type is Adenocarcinoma. Squamous is a cell in the body that are thin and flat and they look like fish scales. They are found in the tissue
of the body and they form the surface of the skin and is a lining on the hollow organs of the body and of the respiratory digestive tracts. Squamous cell

A female breast consists of fatty and fibrous connective tissues. The interior of the breast is divided into about twenty differentsections called lobes.
Each of the lobes is further divided in to lobules, which are structures that contain small milk–producing glands. These glands place the milk into tiny
ducts. These ducts take the milk through out the breast and store in a chamber located below the nipple.

Chemicals are also suspected to cause breast cancer. Xenoestrogens are chemicals with estrogen–like effects, they are found in pesticides and other
common industrial products. Other estrogen–like chemicals that have a stronger association with breast cancer include dieldrin and
beta–hexachloraocyclohexane. Although these chemicals are very weak estrogens, one study showed that exposure to single weak–estrogen
compounds isn't a big risk but a combination of two or more chemicals result in extremely high estrogenic
chemicals. Many women, who took diethylstilbestrol (DES) to prevent miscarriages, increased the risk for breat cancer in their children.
There are lost of ways to prevent cancer or try to prevent it. One of these is reducing your fat intake. One study shows that the result of this is that the
level of estrodiol, the potent form of estrogen decreases. Another way to fight breast cancer is to eat plenty of fruit and vegetables. Many fruits and
vegetables contain chemicals that may be cancer fighters. A concentrated form of limonene, a substance found in citrus skins, has been found to shrink
breast cancer in animals. Some studies have shown that if you breast–fed for more than four months it lowers your risk of the cancer. In a recent study
women who have underwent breast reduction have a low risk of getting breast cancer by forty percent.

Persuasive Speech On Cancer
We as people face War and Disease everyday. So this means that everyday we all have something that is worth fighting for. Cancer is the war we
face in our present times. Despite the fact that our people die to such disease, we spend more money for our own medical issues and needs. Even
though Cancer is one of the leading causes of death within our nation, we strive everyday because everyone has something to live for. We should stand
up to put an end to our pain and suffering. No one should walk miserable or mourn no more. According to research and theory it is proven that there
are treatments for cancer as the war continues to move forward. Cancer is a problem that needs a solution.
Everyday on the news we hear of people dying from or over certain causes. With more than half our population dying downwards, the struggle for
the people becomes very rough. We challenge cancer at the moments it strikes us down. Dr Martin Luther king Jr quoted " The ultimate measure of
a man is not where he stands in moments of comfort and convenience, but where he stands at a time of challenge and controversy". From donations
and fundraisers , we give more money to help the weak and ill so that they could live longer. It is our duty to make sure the people get the help they
deserve. It is our responsibility to make sure that we are doing the right thing in aiding the patient as if we are their nurse or doctor. Our job is to keep

As one of the most prevalent causes of death globally, cancer has been a main focus for bioengineers. While it is understood that, to treat cancer,
malignant tissue must be resected, many issues arise when these tumors are not removed thoroughly, when the tumors are not determined accurately, or
when more time has passed for the cancer to spread to other parts of the body. Currently, there are various technologies and applications that are being
researched such as the application of microfluidic devices (Han, Park and Kim). Many of these emerging technologies are important to continue

Although bacteria can colonize tumors and have been used in successful human trials in cancer treatment, to be successful in recognizing the tumors, it

Cancer is a group of diseases characterized by an uncontrolled growth of abnormal cells. If the spread of these abnormal cells is not controlled, cancer
can cause death. Most cancers take the form of tumors, although not all tumors are cancers. A tumor is simply a mass of new tissue that serves no
physiological purpose. It can be benign, like a wart, or malignant, like cancer. Benign tumors are made up of cells similar to the surrounding normal
cells and are enclosed in a membrane that prevents them from penetrating neighboring tissues. They are dangerous only if their physical presence

These symptoms are not always warning signs of cancer. They can also be caused by less serious conditions. It is important to see a doctor if any of
these symptoms occur. Only a doctor can make a diagnosis. A person shouldn't wait to feel pain because early cancer usually does not cause pain.
Observation is the most widely available examination for the detection of cancer. It is useful in identifying suspicious lesions in the skin, lip, mouth,
larynx, external genitalia and cervix. The second most available detection procedure is palpation. It is particularly valuable in detecting lumps, nodules,
or tumors in the breast, mouth, salivary glands, thyroid, subcutaneous tissues, anus, rectum, prostate, testes, ovaries and uterus and enlarged lymph
nodes in the neck, axilla or groin.
Internal cancers require an extension of observation through endoscopes, x–rays, magnetic resonance imaging, and ultrasound. Laboratory test, such as
the Pap smear, and occult blood testing of the feces have also proven helpful for some of the cancers. However, concerns regarding effectiveness and
yield play a particularly important role in decisions to screen for cancers not easily responsive to earlier detection through physical examination. The
performance of these tests is usually measured in terms of sensitivity, specificity, and positive and negative predictive values. The type, periodicity, and

It is estimated that cancer will cause the death of 7.6 million people worldwide in this year alone. Another 4.4 million people will find out that they
have the disease but are not expected to die because of it. Cancer cells either continuously reproduce uncontrollably or do not die when they are
supposed to. These cancer cells can then spread, or metastasize, throughout the body. Cancer cells can metastasize in the human body through blood
circulation, lymph node spread, and micrometastases. Cells can enter small blood vessels and get into the bloodstream. Cancer cells that do that are
called circulating tumor cells. The circulating blood sweeps up cancer cells as the blood is circulating and carries the cancer cells until they become

It can also trap damaged or harmful cells such as cancerous cells. Most cells that go through the lymph system after being broken off are killed.
The cells that survive can settle in a new area and grow, forming new tumors. The spread of cancer cells throughout the body by lymph node spread
is another example of metastasizing. Micrometastases is when the cancer spread or metastasize is to small to see. Some of these types of cancers can
be detected by blood samples but they cannot be discovered on any type of scan. If a doctor finds or thinks that it is likely that micrometastases are
present, extra measures such as chemotherapy will have to start being taken. The aim to to get rid of any of the cancerous cells before they are even
large enough to discover on a scan. All three of the cancer spreads listed above are extremely dangerous. It is bad enough when someone has cancer
in just one prat of their body. When they find that it has moved and expanded to other areas, it it just devastating. Pathologists need to know about all
of the different types of metastases so that they can better assess the situation and try to keep the cancer from spreading. This is because the pathologist
is the one who actually diagnoses the cancer, a regular doctor does not. Either way, understanding how cancer spreads through the body can increase the
likelihood that the cancer could be contained and not

Genetic Changes And Cancer Essay
Genetic Changes and Cancer
Cancer is a genetic disease caused by certain changes to genes that control the way our cells function, especially how they grow and divide. Genes
carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls
and become cancer. Genetic changes that promote cancer can be inherited from our parents if the changes are present in germ cells, which are the
reproductive cells of the body (eggs and sperm). Such changes, called germline changes, are found in every cell of the offspring. In general, cancer
