12 million people are affected by cancer in India. 55 per cent of cancers are preventive. 65 percent of cancers are detected in the third and fourth stages delaying treatment. With India’s population explosion, the no of cancer cases are also increasing proportionately. In 2010 alone one million new cancer cases were detected in India. More number of cases are observed in urban India than in rural areas. Lung cancer is seen more in men and in women it is the breast cancer. This too observed more in urban people. The absolute number of new cancers and cancer deaths continues to increase, and there is clear evidence that certain human behaviors are influencing these increases. The 4 major factors of lifestyle that continue to be causally related to certain cancers—tobacco use, an unhealthy diet, inadequate exercise, and excessive exposure to ultraviolet radiation—are each independently important in their effects on the genetic and molecular processes that result in the malignant transformation of human cells. There is both irrefutable and otherwise strong evidence that 4 common cancers that occur in India—lung cancer, colon/rectal cancer, breast cancer, and prostate cancer-and a less common cancer, malignant melanoma, have etiologic factors that are lifestyle based and therefore controllable through alterations in human behavior. These cancers and the evidence that lifestyle is important in the causation and/or prevention of the disease is the subjects of this review.
