Study says obesity may soon be top cancer cause

If its rates keep climbing, obesity could rise from causing 8 percent of all cancers in Europe, to becoming the top cause in women, according to an Associated Press article published by the Washington Post yesterday.

“Obesity is catching up at a rate that makes it possible it could become the biggest attributable cause of cancer in women within the next decade,” said Andrew Renehan, a cancer expert at the University of Manchester. Renehan presented his findings to a joint meeting of the European Cancer Organisation and the European Society for Medical Oncology in Berlin on Thursday.

Renehan and colleagues designed a model to estimate the number of cancers that could be blamed on being fat in 30 European countries. In 2002, they calculated that 70,000 cases of cancer out of about 2 million cancer cases were attributable to being overweight or obese. By 2008, the number had jumped to at least 124,000.

Colorectal cancer, breast cancer in menopausal women and endometrial cancer accounted for 65 percent of all cancers linked to being fat. Renehan said that in the U.S., some studies found obesity was responsible for up to 20 percent of cancers.
