Study results: Patients who undergo weight-loss surgery reduce risk of cancer

Article-Study results: Patients who undergo weight-loss surgery reduce risk of cancer

Montreal—Results of a new study suggest that morbidly obese people who undergo weight-loss surgery significantly reduce their risk of cancer, reports Reuters.

Over a five-year period, researchers at Montreal’s McGill University tracked 1,035 morbidly obese patients—defined as being at least 100 pounds overweight—who had undergone bariatric surgery, and monitored 5,746 patients who did not have the surgery but matched the surgery group in age, sex and weight.

The study found that those who underwent bariatric surgery had about an 80 percent lower risk of developing cancer. Specifically, says the study, bariatric-surgery patients were 85 percent less likely to develop breast cancer and 70 percent less likely to develop colon cancer. Reductions in the risk for pancreatic, skin and uterine cancer and non-Hodgkin’s lymphoma also were noted.

Reuters says the study supports research published last year in the New England Journal of Medicine that obese people who undergo bariatric surgery have a lower risk of death from cancer as well as from heart disease and diabetes, compared with obese people who do not have the procedure.
