Excess weight contributes to more than 7pc of cancers
More than seven per cent of cancer cases in the US are attributable to excess body weight, a new study reports.
Previous studies have established a link between body fat and at least a dozen cancers, with the highest risks for liver, uterine and aesophageal cancers. The new report, in JAMA
Oncology, found that from 2011 to 2015, among people 30 and older, 4.7 per cent of cancers in men and 9.6 per cent of those in women were attributable to excess weight — some 37,670 cancers in men, and 74,690 in women every year. The lead author, Farhad Islami, a scientific director at the American Cancer Society, said that the fat-attributable portion of cancer cases is likely to increase in coming years with increasing obesity.
