Tobacco is India's biggest cancer worry

"…early menarche and late menopause raise breast cancer risk by exposing a woman to oestrogen over a longer time," says Dr Sameer Kaul, surgical oncologist at Apollo Hospitals. Simply put, periods before the age of 12 and menopause after 55 is a cancer-risk, as is having first child after 35.

Globally, 12.7 million new cancer cases occur each year, with 7.6 million deaths, reported the Cancer Journal for Clinicians Friday. Breast cancer is the top cancer in women worldwide, accounting for 23% cases and 14% of cancer deaths.

Lung cancer is the most common in men — 17% new cases and 23% deaths.

Smokers are up to 22 times more likely to develop lung cancer than non-smokers. “Tobacco use is the single-largest preventable cause of cancer and discouraging use the most cost-effective intervention,” says Dr GK Rath, chief, Rotary Cancer Institute, AIIMS.

“Tobacco kills 10 lakh people a year, more than AIDS, murders, suicides, alcohol and drug abuse put together.”
