A new study shows that weight loss surgery may affect a person’s risk of developing cancer.
The national population-based study used data from the Hospital Episode Statistics database in England collected between 1997 and 2012.
A total of 8794 obese patients who underwent gastric bypass, gastric banding, or sleeve gastrectomy were enrolled as well as 8794 obese individuals who did not have surgery.
The researchers found that patients who underwent surgery had a 77% decreased risk of developing hormone-related cancer (breast, endometrial or prostate cancer) when compared with patients who did not have surgery.
Moreover, gastric bypass surgery resulted in the largest risk reduction (84%) for hormone-related cancer but was linked to a greater risk of colorectal cancer.
The team suggests that more studies are needed to understand the biological mechanisms behind these findings.
The study is published in the British Journal of Surgery.
