• Primary liver cancer
• Ovarian cancer
• Prostate cancer
• Thyroid cancer
 Dietary factors
Smoked fish - stomach cancer

 Others-sunlight, radiation air pollution and water
pollution, medication; pesticides etc are related to
cancer.
B) GENETIC FACTORS
 Retinoblastoma occurs in children of the same
parent
 Mongols are more likely to develop cancer
(leukemia) than normal children.
 However genetic factors are less conspicuous and
more difficult to identify.
PATHOPHYSIOLOGY OF THE
MALIGNANT PROCESS
 Disease process that begins when an abnormal cell
is transformed by the genetic mutation of the
cellular DNA
 This abnormal cell forms a clone and begins to
proliferate abnormally,
 The cells acquire invasive characteristics, and
changes occur in surrounding tissues. The cells
infiltrate these tissues and gain access to lymph
and blood vessels, which carry the cells to other
areas of the body.
SIGNS AND SYMPTOMS
 LOCAL SYMPTOMS
 Lump or swelling
 Haemorrhage
 Pain or ulceration
 SYMPTOMS OF METASTASIS
 Enlarged lymph nodes
 Cough
 Haemoptysis
 Hepatomegaly
 Bone pain
 Fracture
 Neurological symptoms
SYSTEMIC SYMPTOMS
 Weight loss
 Poor appetite
 Fatigue
 Cachexia
 Diaphoresis
 Anaemia
CAUTION
 C: Change in bowel or bladder habits
 A: A sore that does not heal
 U: Unusual bleeding or discharge
 T: Thickening or lump in the breast or
elsewhere
 I: Indigestion or difficulty in swallowing
 O: Obvious change in a wart or mole
 N: Nagging cough or hoarseness
CLASSIFICATION
BSED ON THE TISSUE PRESUMED TO BE
THE ORIGIN OF THE TUMOR…..
 Carcinoma: Malignant tumors derived from epithelial
cells. This group represents the most common cancers,
including the common forms of breast, prostate, lung
and colon cancer
 Sarcoma: Malignant tumors derived from connective
tissue, or mesenchymal cells.
 Lymphoma and leukemia: Malignancies derived from
hematopoietic (blood-forming) cells
 Germ cell tumor: Tumors derived from totipotent cells.
In adults most often found in the testicle and ovary; in
foetuses, babies, and young children most often found
on the body midline, particularly at the tip of the
tailbone
 Blastic tumor or blastoma: A tumor (usually malignant)
which resembles an immature or embryonic tissue.
Many of these tumors are most common in children.
BASED ON INVASIVE NATURE:
Benign
Malignant
BENIGN MALIGNANT
 Grows slowly

 Recurrence not common
 Metastasis never occur
 Neoplasm is not harmful to
host
 Prognosis is very good
 Grows rapidly
 Infiltrating surrounding
tissues
 Capsule absent
 Poorly differentiated cell
 Recurrence is common
 Metastasis is very common
 Neoplasm is harmful to the
host
 Poor prognosis
BASED ON THE TISSUE OF
ORIGIN..

Drugs that can destroy cancer cells. It
also referred as ‘ cytotoxic drugs’ which
affect rapidly dividing cells by interfering
with the DNA duplication or the separation
of newly formed chromosomes.
 MONOCLONAL ANTIBODY THERAPY
In this, therapeutic agent is an
antibody which specifically builds to a
protein on the surface of the cancer cells.

NATIONAL CANCER REGISTRY PROGRAMME
 National Cancer Registry Programme was
launched in 1982 by Indian Council of Medical
Research (ICMR) to provide true information on
cancer prevalence and incidence. Cancer
registration is the process of systematically and
continuously collecting information on
malignant neoplasm.
Objectives

cancer problem in India;
2. To undertake epidemiological investigations and
advice control measures; and
3. Promote human resource development in cancer
epidemiology.
2 TYPES OF REGISTRIES
1. Population Based Cancer Registry and
2. Hospital Based Cancer Registries
 Population based registries:
There are six in number ; 5 in urban areas
( delhi , Bhopal, Mumbai, Bangalore,Chennai) and
one in rural areas ( barshi in Maharashtra).
 Hospital based registries:
At Chandigarh, dibrugarh, thiruvanathapuram,
Bangalore, Mumbai, and Chennai , six hospital based
registries are maintained.
CANCER ATLAS
 To bridge the gap, a project of atlas of the cancer
in India was started under WHO-ICMR since 2003
mainly to have an idea of patterns of cancer in
several parts of the country.
 Under this programme ICMR has developed an
Atlas of cancer in India based on the information
collected for the year 2001-02 from 105
collaborating centres to have an idea of the
pattern of cancer across the country.
Main objectives:
(i) To obtain an overview of patterns of
cancer in different parts of the country;
(ii) To calculate estimates of cancer
incidence wherever feasible.
JOURNAL PRESENTATION
 Indian Journal of cancer
 Title:- Risk factors of female breast carcinoma: A case
control study at Puducherry
 Investigators:-SM Balasubramaniam, SB Rotti, S
Vivekanandam
 Objective: To identify and quantify various demographic,
reproductive, socio-economic and dietary risk factors
among women with breast cancer.
 Study Design: Case control study.
 Study Period : February 2004 to May 2005.
 Study Setting: Departments of Surgery, Medicine and
Radiotherapy of JIPMER
 Materials and Methods: Cases were women with
pathologically confirmed breast cancer. Controls
were age-matched women from medicine and
surgery wards without any current breast
problem or previous breast cancer. A total of 152
cases and 152 controls were enrolled. They were
interviewed for parity, breast feeding, past history
of benign breast lesion, family history and dietary
history with a pre-tested interview schedule after
obtaining informed written consent.
 Results:The significant risk factors were previous
history of biopsy for benign breast lesion 10.4,
nulliparity 2.4 (1.14-5.08), consumption of fats more
than 30 g/day 2.4 (1.14-5.45) and consumption of oils
containing more of saturated fat 2.0 (1.03-4.52).
 Conclusions: Nulliparity, past history of benign
breast lesion, high fat diet and consumption of oils
with more saturated fats were the risk factors.
 Journal name:- Journal of Physiology and Pharmacology
Advances
 Title:- A Case Control Study to Assess Impact of Risk
Factors on Trends of Lung Cancer
 Investigators:- Arunima Gupta, Siddhartha Das,
Shatarupa Dutta, Santu Mondal, Krishnangshu Bhanja
Choudhuri, Sumana Maiti.
 Objective:- Identify impact of risk factors on changing
trends of lung cancer in a case control study
 Duration:- 2006 to 2010 included newly diagnosed
patients of histological proven lung carcinoma
attending the radiotherapy department
 Methodology:- For each case, one control was
identified and matched with same sex, age ± 5
years, and unmatched for residence, smoking
status and socioeconomic condition. For
categorical variables, Chi Square and Fisher’ test
and for numerical variables t test and Mann
Whitney tests were used. All univariate analyses
used ANOVA test.
 RESULT:-
 During the study period 1524 cases and their controls
were accounted. Change in trend was observed in
patients diagnosed at younger age of 57.48 ± 0.56 years
in 2010 with adenocarcinoma unlike 62.89 ± 1.21 years
in 2006. Females show increase in incidence of lung
cancer in 2010, p value < 0.001 . The “active” smokers
and years of smoking were significantly high among
cases. The incidence of squamous cell carcinoma declined
from 47.4% in 2006 to 15% in 2010 whereas
adenocarcinoma increased, p value 0.001. Significant
change in trend involving younger age at presentation
specially for female who also show increased incidence of
lung cancer has been observed. This hypothesis needs
confirmation through further studies.

  • 81. NATIONAL CANCER REGISTRY PROGRAMME  National Cancer Registry Programme was launched in 1982 by Indian Council of Medical Research (ICMR) to provide true information on cancer prevalence and incidence. Cancer registration is the process of systematically and continuously collecting information on malignant neoplasm.
  • 82. Objectives 1. To generate authentic data on the magnitude of cancer problem in India; 2. To undertake epidemiological investigations and advice control measures; and 3. Promote human resource development in cancer epidemiology.
  • 83. 2 TYPES OF REGISTRIES 1. Population Based Cancer Registry and 2. Hospital Based Cancer Registries
  • 84.  Population based registries: There are six in number ; 5 in urban areas ( delhi , Bhopal, Mumbai, Bangalore,Chennai) and one in rural areas ( barshi in Maharashtra).  Hospital based registries: At Chandigarh, dibrugarh, thiruvanathapuram, Bangalore, Mumbai, and Chennai , six hospital based registries are maintained.
  • 85. CANCER ATLAS  To bridge the gap, a project of atlas of the cancer in India was started under WHO-ICMR since 2003 mainly to have an idea of patterns of cancer in several parts of the country.  Under this programme ICMR has developed an Atlas of cancer in India based on the information collected for the year 2001-02 from 105 collaborating centres to have an idea of the pattern of cancer across the country.
  • 86. Main objectives: (i) To obtain an overview of patterns of cancer in different parts of the country; (ii) To calculate estimates of cancer incidence wherever feasible.
  • 87. JOURNAL PRESENTATION  Indian Journal of cancer  Title:- Risk factors of female breast carcinoma: A case control study at Puducherry  Investigators:-SM Balasubramaniam, SB Rotti, S Vivekanandam  Objective: To identify and quantify various demographic, reproductive, socio-economic and dietary risk factors among women with breast cancer.  Study Design: Case control study.  Study Period : February 2004 to May 2005.  Study Setting: Departments of Surgery, Medicine and Radiotherapy of JIPMER
  • 88.  Materials and Methods: Cases were women with pathologically confirmed breast cancer. Controls were age-matched women from medicine and surgery wards without any current breast problem or previous breast cancer. A total of 152 cases and 152 controls were enrolled. They were interviewed for parity, breast feeding, past history of benign breast lesion, family history and dietary history with a pre-tested interview schedule after obtaining informed written consent.
  • 89.  Results:The significant risk factors were previous history of biopsy for benign breast lesion 10.4, nulliparity 2.4 (1.14-5.08), consumption of fats more than 30 g/day 2.4 (1.14-5.45) and consumption of oils containing more of saturated fat 2.0 (1.03-4.52).  Conclusions: Nulliparity, past history of benign breast lesion, high fat diet and consumption of oils with more saturated fats were the risk factors.
  • 90.  Journal name:- Journal of Physiology and Pharmacology Advances  Title:- A Case Control Study to Assess Impact of Risk Factors on Trends of Lung Cancer  Investigators:- Arunima Gupta, Siddhartha Das, Shatarupa Dutta, Santu Mondal, Krishnangshu Bhanja Choudhuri, Sumana Maiti.  Objective:- Identify impact of risk factors on changing trends of lung cancer in a case control study
  • 91.  Duration:- 2006 to 2010 included newly diagnosed patients of histological proven lung carcinoma attending the radiotherapy department  Methodology:- For each case, one control was identified and matched with same sex, age ± 5 years, and unmatched for residence, smoking status and socioeconomic condition. For categorical variables, Chi Square and Fisher’ test and for numerical variables t test and Mann Whitney tests were used. All univariate analyses used ANOVA test.
  • 92.  RESULT:-  During the study period 1524 cases and their controls were accounted. Change in trend was observed in patients diagnosed at younger age of 57.48 ± 0.56 years in 2010 with adenocarcinoma unlike 62.89 ± 1.21 years in 2006. Females show increase in incidence of lung cancer in 2010, p value < 0.001 . The “active” smokers and years of smoking were significantly high among cases. The incidence of squamous cell carcinoma declined from 47.4% in 2006 to 15% in 2010 whereas adenocarcinoma increased, p value 0.001. Significant change in trend involving younger age at presentation specially for female who also show increased incidence of lung cancer has been observed. This hypothesis needs confirmation through further studies.
