In June 2008, Canadian bariatric surgeon Nicolas Christou and his colleagues published a remarkable paper showing that obese adults who undergo bariatric surgery to lose weight may reduce their risk for developing some cancers by as much as 80% (Surg Obes Relat Dis 2008;4:691-695).
Dr. Christou’s report was remarkable because it marked the first time that weight-loss surgery was shown to affect dramatically the incidence of several specific types of cancer, particularly cancer of the breast and large intestine.
The Swedish Obese Subjects (SOS) study of 2,000 patients who underwent diet therapy or gastric restrictive surgery showed a dramatic reduction in cancer incidence among women who had bariatric surgery (Lancet Oncol 2009;10:653-662).
Studies have shown that a woman with a BMI of 40 has approximately 8 times greater risk of endometrial cancer than someone with a BMI of 25.
Bariatric surgery appears to reduce the death from cancer for both obesity-related and non–obesity-related cancers. Bariatric surgery helps to reduce cancer risk by normalizing hormone levels, reducing insulin resistance and allowing for increased physical activity and improved health.
