While previous studies have shown that bariatric surgery reduces body weight, reverses type 2 diabetes, lowers risk factors related to excess weight and improves heart structure and function, new research suggests that it can also cut cancer risks in women. Study outcomes showed that obese women who undergo bariatric surgery experience a 42 percent drop in their cancer risk.
Exactly why this occurs, and why it is not true for obese men, is not yet clear. Obesity is a known risk factor for colon, breast, endometrial, kidney and esophageal cancers. Researchers have found that the surgery-related weight loss and drop in caloric intake did not seem to be solely responsible for the decline in the women’s cancer risk, according to the report in the July issue of Lancet Oncology.
While this link is not completely understood and will require more research, it adds support to the notion that the association between obesity and cancer risk is causal.
The American Cancer Society encourages maintaining a healthy body weight, eating a healthy diet and exercising regularly to reduce the risk of cancer. Now studies further support that notion.
