Estimated rise in new cancer cases by 2030, from 12.7 million new cases in 2008 to 22.2 million by 2030. Researchers say the surge can be largely attributed to demographic and lifestyle factors like poor diet, lack of exercise, smoking and drinking, which increase the risk of colon, lung and breast cancers. In many countries, a rise in such lifestyle-related cancers has offset drops in rates of cancer associated with infection, according to the researchers who analyzed global data on cancer cases. About 90% of the estimated cancer spike is predicted to occur in the poorest nations. [via The Lancet Oncology]
