"The greatest benefit from surgery was among obesity-associated cancers. Postmenopausal breast cancer dropped by 42 percent. Endometrial cancer was down 50 percent. Colon cancer dropped 41 percent, and the risk for pancreatic cancer was lowered by 54 percent. Schauer explains the lower cancer risk is partially tied to estrogen levels. The weight loss surgery reduces a person's estrogen level.

@Apple203 As soon as I hit 5 years, my oncologist started encouraging me to get RNY surgery. He told me the studies were coming back that WLS reduced recurrence risks substantially. Thanks for sharing this study!!
