Bariatric surgery reduces the risk of developing cancer by 37%

Three new studies show that losing a large amount of weight through bariatric surgery can significantly reduce your risk of developing or dying from cancer. According to a study presented Tuesday at the annual meeting of the American Society for Metabolic and Bariatric Surgery (ASMBS) in Dallas, obese people who had bariatric surgery were at least half as likely to develop certain types of cancer and more than three times times less likely to die of cancer than obese people who did not have the procedure.

According to results published June 3 in the Journal of the American Medical Association, another much larger trial conducted by the Cleveland Clinic found similar, albeit smaller, benefits of bariatric surgery: a 32% cancer risk lower and a 48% lower risk of cancer-related death.

Weight reduction has a dose-dependent association with cancer risk, according to the findings: the more weight you lose, the lower your cancer risk. Another study presented at the ASMBS Summit on Tuesday found that bariatric surgery reduced the risk of colon cancer by 37%. %.


To achieve this protection against cancer, people must lose at least 20% of their body weight, which is far beyond the capacity of those seeking to lose weight through diet and exercise, according to the researcher principal, Dr. Ali Aminian, director of Bariatric at the Cleveland Clinic. and Metabolic Institute.

More than 42% of Americans are obese, according to the Centers for Disease Control and Prevention. Their extra weight increases their risk for 13 malignancies, which account for two in five cancers diagnosed in the United States each year.

Given the global obesity epidemic, obesity is expected to overtake smoking as the leading cause of cancer in the near future, according to Aminian.

According to a report presented at the ASMBS meeting, the first study compared more than 2,100 bariatric surgery patients to more than 5,500 obese adults who qualified for the treatment but did not receive it.

According to the researchers, breast cancer (1.4% versus 2.7%), gynecological cancer (0.4% versus 2.6%), kidney cancer (0.10% versus 0.80%) , brain cancer (0.20% versus 0.90%), lung cancer (0.20% versus 0.60%) and thyroid cancer (0.10% versus 0.70% ) were all significantly reduced by bariatric surgery.

The bariatric surgery group also had a reduced incidence of any new malignancy (about 5.2% versus just over 12%) and a higher survival rate over a decade (93% versus 79%).
