This document discusses the history and current state of cancer. It notes that cancer occurs when cells grow out of control and details some key events in cancer's history such as the first descriptions in ancient Egypt and Greece. The document outlines several causes of cancer like tobacco, viruses, and radiation. It discusses how cancer spreads and common screening tests for early detection of breast, cervical, prostate, colon, and lung cancers. The takeaway message is that cancer has affected humanity for millennia but screening and research into molecular mechanisms can help control and potentially cure cancer at early stages.
These treatments includes surgeries, radiations, chemical agents, or biological therapies
A type of treatment that uses drugs or other substances to identify and attack specific type of cancer cells with less harm to normal cells
Cancer is the name given to a collection of related diseases. In all types of cancer, some of the body's cells begin to divide without stopping and spread into surrounding tissues. Cancer can start almost anywhere in the human body, which is made up of trillions of cells.

Cancer that forms in tissues of the pharynx
(the hollow tube inside the neck that starts behind the nose and ends at the
top of the windpipe and esophagus). Throat cancer includes cancer of the
nasopharynx (the upper part of the throat behind the nose), the oropharynx (the
middle part of the pharynx), and the hypopharynx (the bottom part of the
pharynx). Cancer of the larynx (voice box) may also be included as a type of
throat cancer. Most throat cancers are squamous cell carcinomas (cancer that
begins in thin, flat cells that look like fish scales). Also called pharyngeal
cancer.
The intensifying global focus on oncology reflects its increasing impact on patients and expanding share of healthcare expenditure. Relative to other parts of the healthcare system, oncology brings high levels of uncertainty—in terms of the nature and rate of innovative treatments, the willingness by payers to reimburse care at current levels, and the shifting composition of the cancer patient population from mature and developed markets to low- and middle-income countries. As the sales of cancer treatments rise to $100 billion annually, more intensive scrutiny of this market can be expected and a deeper understanding of global oncology trends will be required by all stakeholders.
Different types of diseases and infections have always threatened man.However, one disease that is considered almost deadly and has a very high rate of recurrence is cancer.

INTRODUCTION
Cancer is an abnormal growth of functioning cell
not in the control of body hormonal system and
hampering functioning of other body system
Cancer is the general name for a group of more
than 100 diseases. All cancers start because
abnormal cells grow out of control.
When cells continue multiplying when the body
doesn't need them. The result is a mass or growth,
also called a TUMOR.
Cancer Overview
These growths are considered either BENIGN
or MALIGNANT
NEOPLASM - Abnormal growth of cells
BENIGN -Neoplasms are not cancerous
MALIGNANT - Neoplasms are cancerous
CHARACTERISTICS OF CANCER CELLS
Lack differentiation
Have abnormal nuclei
Form tumors
Mitosis controlled by contact
with neighboring cells
Cancer cells have lost contact
inhibitor

STAGES OF CANCER
Stage 0. This stage describes cancer in situ. In situ means "in place." Stage 0 cancers are still located in the place they started. They have not spread to nearby tissues. This stage of cancer is often curable. Surgery can usually remove the entire tumor.
Stage I. This stage is usually a cancer that has not grown deeply into nearby tissues. It also has not spread to the lymph nodes or other parts of the body. It is often called early-stage cancer.
Stage II and Stage III. In general, these 2 stages are cancers that have grown more deeply into nearby tissue. They may have also spread to lymph nodes but not to other parts of the body.
Stage IV. This stage means that the cancer has spread to other organs or parts of the body. It may be also called advanced or metastatic cancer.
Name of Cancer
Name of Cancer is given according to cell of origin , site of origin , stage of disease
About 200 cancer are estimated
Broadly Classified as Blood related
Cancer ( leukemia, Myeloma, lymphoma)
And then other Big Category is solid tumors
and this are fether branded as squamous
cell carcinomas , adenocarcinomas ,
sarcomas
In male Lung , larynx, tongue , Prostrate cancer is common
In female breast, Cervical , Gall Bladder , Endometrial cancer is common
TYPES OF CANCER
The following five broad categories indicate the tissue and blood classifications of cancer
Carcinoma
A carcinoma is a cancer found in body
tissue known as epithelial tissue that covers
or lines surfaces of organs, glands, or body
structures. For example, a cancer of the
lining of the stomach is called a carcinoma.
Many carcinomas affect organs or glands
that are involved with secretion, such as
breasts that produce milk. Carcinomas
account for 80-90% of all cancer cases......
a presentation that helps to educate us about the rising incidence of cancer in our environment. it also tells us about the silent nature of some cancers, which at the point of diagnosis is in the late stages
Cancer might be one of the most feared diseases worldwide. No matter what type of cancer we look at, it is deadly and affects thousands and millions of individuals around the world each year. And one such cancer is Nasopharyngeal cancer.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

3. How common is cancer
• According to national cancer control
programme – there are nearly 2.5 million
cancer patients in India
• About 0.7 million new cases are
diagnosed each year, and nearly half of
them die
• More than 60% of these patients are in
the age of 35-60, prime of their life
• It is expected that with improved life
expectency – the number of cases will
triple in the coming years
4. • About 1 in 4 of us will get cancer
• About 1 in 5 of will die due to
cancer
5.
6. Normal cell division
• There are trillions of cells in our body
• Healthy cells are programmed to
“know what to do and when to
do it”.

15. What is Cancer
• Cancer is a general name for more
than 100 different diseases
• The common point about all these
different diseases is that a particular
cell of the body is growing out of
control
• Cancer cells donot know “what to
do, and when to do”
• This division uses up all the
resources required by other cells of
the body
16. Some commonly used terms
• Neo-plasm – new growth
• Tumor – swelling caused by
neoplasm
• Benign neoplasm – one which is
restricted by its capsule – doesnot
spread to other areas of body
• Malignant – one which spreads to
different parts of the body
19. • Papyrus described 8 cases of ulcers
of breast treated by cauterization by
a tool he called – the fire drill
• He had said – the disease has no
cure
20.
21. History
• Hippocrates – 460-370 BC
• Described several types of cancers –
called them carcinos (crab)
• Cut surface of tumors with veins in all
directions
23. CELCUS AND GALEN
• Celcus (25 BC) translated carcinos
into latin – cancer
• Galen suggested the word oncos for
swelling – Oncology thus was named
24. Cause of cancer Humoral theory
• Though Hippocrates, Celcus and Galen
described cancer, they did not know the
cause
• Cause of cancer was said to be
imbalance of body fluids
• black/yellow bile,blood and phlegm
• Cancer was said to be caused by excess of
black bile
• Accordingly treatment was change of
diet/blood letting /laxatives
25.
26. Morgagni
• In 1761, Morgagni first performed
autopsies
• He studied postmortem findings and
suggested causes of diseases
• This lead the foundation of
scientific study of cancer oncology
29. Era of cancer surgery
• The famous Scottish surgeon John
Hunter (1728−1793) suggested
that some cancers might be cured
by surgery.
• If the tumor had not invaded nearby
tissue and was “moveable,” he said,
“There is no impropriety in removing
it.”
• He conducted a lot of autopsies and
studied cancer
32. Primitive surgery
• No asepsis / anaesthetic techniques
were available
• Mortality was more due to
secondary infections that cancer
per se
33. RECURRED
• It took nearly a century for the
development of anesthesia and
asepsis
• This allowed surgery to flourish and
classic cancer operations such as the
radical mastectomy could be done
effectively
• Any and every cancer was removed
– this prolonged life somewhat – but
cancer recurred
34. • Till this time – no one had
actually seen cancer cells!!!
35. Birth of microscopic
pathology
• The 19th century modern microscope
was invented and cancerous tissue
could be studied.
• Rudolf Virchow, often called the
founder of cellular pathology,
linked microscopic findings with
cancer types.
36.
37. First actual cause of cancer
discovery
• In 1713, Bernardino Ramazzini, an Italian
doctor, reported the virtual absence of
cervical cancer and relatively high
incidence of breast cancer in nuns
• This was linked to their celibate life style
• This observation was an important step
toward identifying and understanding the
importance of hormones and cancer risk
38.
39. Scrotal cancer
• In 1775, Percival Pott of Saint
Bartholomew’s Hospital in London
described an occupational cancer in
chimney sweeps, cancer of the scrotum
• was caused by soot collecting in the skin
folds of the scrotum.
40.
41. Tobacco
• Thomas Venner of London was
one of the first to warn about
tobacco dangers in his Via Recta,
published in London in 1620.
• He wrote that “immoderate use of
tobacco hurts the brain and the
eye and induces trembling of the
limbs and the heart.”
42. • And 150 years later, in 1761, only a
few decades after recreational
tobacco became popular in London,
John Hill wrote a book entitled Cautions Against the Immoderate
Use of Snuff.
43. • Inspite of this, tobacco use continued
unabeted
• Lead to an epidemic of sorts, of
tobacco related cancers
44. • These first observations linking
tobacco and cancer led to
epidemiologic research many years
later (in the 1950s and early 1960s)
which showed that smoking causes
lung cancer and led to the US
Surgeon General’s 1964 report
Smoking and Health.
45. • This report lead to some regulations
on tobacco companies
• They had to affix warnings on their
products
47. Genetic cause
• The genetic basis of cancer was
proposed by German zoologist
Boveri in 1902
• He suggested the mutations of
chromosomes lead to cancer
48. Radiotherapy
• Marie curie discovered radium, and
radiation at the end of 19th century
• This marked the discovery of first
non surgical mode of cancer
treatment
51. Complete cancer cure
• During World war II, the nuclear
bombings of Hiroshima and Nagasaki
took place
• It was observed that the radiation of
the bombings destroyed the marrow
of the victims
• This in turn gave a hope of curing
cancer completely by radiation
62. Signs and symptoms of
cancer
• Depends on the location
–
–
–
–
–
–
–
Change in bowel or bladder habits
A sore that does not heal
Unusual bleeding or discharge
Thickening or lump in breast or elsewhere
Indigestion or difficulty in swelling
Obvious change in wart or mole
Nagging cough or hoarseness
69. Can we treat cancer??
• Cancer cells are our cells –
• killing them = killing ourselves
• Main treatments available
– Surgery – Recurs
– Chemotherapy – damages normal cells
– Radiotherapy – damages nearby areas
70. Newer treatments
• Imatinib – revolutionized treatment
of CML
• Herceptin – for treatment of breast
cancer
• Rituximab – against NHL
72. What is screening??
• looking for cancer before a person
has any symptoms
• When abnormal tissue is found early
stage, it may be possible to treat it
completely
• Following cancers are amenable to
screening
–
–
–
–
–
Breast
Prostate
Cervix
Colon and rectum
Lung
74. Breast cancer screening
• Has lead to a 15-20% reduction in
deaths due to breast cancer
• American cancer society
recommends breast cancer
screening for all women more
than age 40 , every year
• Includes
– Mammography
– Clinical breast examination
– Breast self examination
82. Prostate Cancer screening
• Screening can be started for
– Moderate risk males – age 50
– High risk males – age 45
– Very high risk males – age 40
• Screening consists of
– Digital rectal examination
– PSA examination
88. Lung cancer screening
• Guidelines recommending annual
low-dose CT lung cancer
screening have been approved by
the US Preventive Services Task
Force.
• The recommendations apply to
individuals aged between 55 and
80 who are at high risk for lung
cancer as a result of heavy
smoking.
89.
90. Take home message
• Cancer is a group of diseases affecting
human kind since ages
• It is controllable – not yet completely
curable at early stages
• Screening programs help in reducing
morbidity and mortality from cancer
• Gearing cancer research towards knowing
the molecular mechanisms of cancer can
help in developing treatment modules
