Slide 1:Think of the people you know. How many of them have had cancer? How many more will get it? By
Satish.D
Slide 2:The GLOBOCAN 2002 database presents estimates of the incidence and prevalence of and mortality from 27 cancer for all countries in the world in 2002.
Slide 3:Urbanization, industrialization, changes in lifestyles, population growth and ageing all have contributed for epidemiological transition in the country.
The absolute number of new cancer cases is increasing rapidly, due to growth in size of the population, and increase in the proportion of elderly persons as a result of improved life expectancy following control of communicable diseases.
In India, the life expectancy at birth has steadily risen from 45 years in 1971 to 62 years in 1991, indicating a shift in demographic profile4.
It is estimated that life expectancy of Indian population will increase to 70 years by 2021–25 .

Slide 13:Cancer is a leading cause of death worldwide: it accounted for 7.9 million deaths (around 13% of all deaths) in 2007.
Lung, stomach, liver, colon and breast cancer cause the most cancer deaths each year.
About 30% of cancer deaths can be prevented
Tobacco use is the single most important risk factor for cancer.
Slide 14:lung (1.4 million deaths/year);
stomach (866,000 deaths)
liver (653,000 deaths)
colon (677,000 deaths)
breast (548,000 deaths)
Slide 15:About 80% of all cancer deaths in 2007 occurred in low- and middle-income countries.
Deaths from cancer worldwide are projected to continue rising, with an estimated 12 million deaths in 2030.
Slide 16:The most frequent types of cancer worldwide (in order of the number of global deaths) are:
Among men - lung, stomach, liver, colorectal, oesophagus and prostate.
Among women - breast, lung, stomach, colorectal and cervical.
Cancers that are most often cured are breast, Liver ,Cervix prostate, colon and skin, if they are diagnosed early.
