Weight loss surgery may reduce the risk of developing colorectal cancer by one-third, according to an analysis of all relevant published studies. The findings are published in BJS (British Journal of Surgery).

The BJS analysis, which included seven studies with a total of 1,213,727 patients and an average follow-up of seven years, was conducted because individual studies have presented conflicting results.
