Weight-loss surgery found to slash cancer risk and mortality

Bariatric surgery, also commonly referred to as weight-loss surgery, can help to reduce the risk of developing six different types of cancer associated with obesity, new research suggests.


For the study, more than 1,600 obese people who had either gastric bypass surgery or sleeve gastrectomy surgery were compared to a control group of over, 2,100 obese individuals with obesity who did not undergo surgery. Both groups were matched in terms of age, sex and BMI.


According to the study, the findings of which were presented at the 2022 annual meeting of the American Society for Metabolic and Bariatric Surgery (ASMBS), people who underwent bariatric surgery were also less likely to develop any type of cancer compared to their obese peers who had not had surgery.


In fact, the study found that only 5.2 percent of people who had bariatric surgery went on to develop some type of cancer during the 10-year study period, compared to 12.2 percent of those who did not have weight loss surgery. Furthermore, the overall 10-year survival rate for patients who underwent surgery was 92.9 percent, while it was just 78.9 percent for the non-surgical group.


Commenting on the study, Dr. Shanu Kothari, president of the ASMBS, said: “Patients live longer after bariatric surgery because they have less cardiac events and less cancers.”
