Ex­cess weight con­trib­utes to more than 7pc of can­cers

The East African - - OUTLOOK -

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.
