Lower risk of colon cancer after bariatric surgery: study
The controversial findings disagree with other research
Bariatric surgery may reduce the risk of colon cancer in patients with obesity, according to findings that contradict previous research.
French researchers used national health-insurance data on more than one million patients with obesity, aged 50-75, with no history of colorectal cancer.

Mean follow-up was 5.7 years for patients who had weight-loss
