Bariatric surgery cuts cancer risk

Morbidly obese patients who have undergone bariatric surgery have a reduced risk of developing cancer, a review confirms.

The review of 13 studies found patients who had weight loss surgery were up to 88% less likely to develop cancer than morbidly obese people who did not have the procedure.

Writing in the journal, Obesity Surgery, the study authors said their data showed bariatric surgery was linked to morbidly obese patients' cancer rates dropping to levels comparable to those of people with normal BMI.
