Diet, exercise could cut cancer rates by third

Diet, exercise could cut cancer rates by third:

"PARIS (AFP) – A third of common cancers could be prevented if people shifted to a sounder diet, exercised more and controlled their weight, researchers said on Thursday.

The report, by the World Cancer Research Fund and the American Institute for Cancer Research, analysed incidence of 12 types of cancer in the United States, Britain, Brazil and China.

Around a third of these cancers could be prevented by better nutrition, physical activity and obesity controls, it estimated.

The figure does not include the benefits of tackling cancer by stopping smoking. Tobacco use alone accounts for about a third of cancers."
