MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Obesity is associated with many types of cancer and bariatric surgery is the most effective treatment for severe obesity. We conducted a retrospective cohort study of patients undergoing bariatric surgery between 2005 and 2012 with follow-up through 2014 using data from Kaiser Permanente using 5 study sites. The study included 22,198 patients who had bariatric surgery matched to 66,427 nonsurgical patients with severe obesity.
We found that bariatric surgery was associated with a reduced risk of cancer. The risk reduction was greatest for the cancers that are associated with obesity including postmenopausal breast, endometrial, colon, and pancreatic cancers, as well as esophageal adenocarcinoma.
