Obesity may become leading cause for cancer, says researcher
Obesity is on its way to being deadlier than smoking as a cause of cancer in the U.S., a leading researcher said. Being obese is currently associated with about 14 per cent of cancer deaths in men and 20 per cent in women, compared with about 30 per cent each for smoking, Dr. Walter C. Willett of the Harvard School of Public Health told the annual meeting of the American Association for the Advancement of Science. He said research is producing increasing evidence associating obesity with a variety of cancers.
