Effective for weight loss, bariatric surgery also has the advantage of reducing the risk of obesity-related cancers.
- Bariatric surgery could reduce obesity-associated cancer risk by around 32%, new study finds
- Also according to this research, this method of weight loss would also reduce the risk of mortality by 48%.
According to a study published in JAMA magazineadults who successfully lose weight after undergoing bariatric surgery would also have a 32% reduced risk of developing cancer.
This cohort study was performed on a group of 5,053 adult patients with obesity who underwent bariatric surgery between 2004 and 2017. The results were then compared to those of a control group of 25,265 obese patients, but not having undergone surgery.
Ten years later, 2.9% of patients in the bariatric surgery group developed cancer associated with obesity, compared to 4.9% in patients in the non-surgical group. Bariatric surgery was also associated with a 48% reduced risk of death from cancer.
Risk reduction also seen with breast cancer
“The striking results of this study indicate that the greater the weight loss, the lower the risk of cancer“, comments Dr. Ali Aminian, lead author of the study and director of the Bariatric & Metabolic Institute at the Cleveland Clinic (USA).
A another study published last February in the magazine obesity came to similar conclusions, this time in the specific case of breast cancer. For the purposes of the work, the team compared the data of 55,781 patients who underwent obesity surgery and those of participants who did not have recourse to this intervention.
Research results have shown that the risks of developing breast cancer were reduced by 15% in women who had bariatric surgery.
