Weight Loss Surgery Associated with Reduced Cancer Risk
July 3, 2014
A review conducted by a Brazilian team of researchers found a possible association between weight loss surgery and a reduction in cancer diagnosis.
The researchers reviewed the results of 13 studies conducted involving cancer rates after weight loss surgery. The combined studies included more than 54,000 patients. Results of the studies indicated that after weight loss surgery patients had cancer risks at similar rates to normal weight patients, nearly a 50% decrease in cancer rates of patients affected by obesity.
Obesity has long been associated with increased risks of certain cancers, most prevalent are breast, colon, esophagus, kidney, pancreatic and endometrial cancers. The American Cancer Society estimates that one in three cancer deaths is linked to excess weight, poor diet, and/or inactivity.
Experts in the United States are hesitant to confirm the connection between weight loss surgery and reduction in cancer rates, however admit there is a possible relation due to hormonal and inflammation changes within the body after weight loss.
