Obese patients who receive bariatric surgery have a risk of cancer reduced by at least a third of the years after the surgery, suggests a study conducted by the university of Cincinnati (United States) and published in the Annals of Surgery.

In France, this surgery is reserved for patients whose body mass index is more than 40 kg/m2, and persons with comorbidities (diabetes, hypertension, etc.) and with BMI greater than 35 kg/m2.

In the past two decades, the number of these interventions has exploded in our country. Since 1997, the number of acts has been multiplied by 24, from 1 950 47 000 operations per year. If the increase in the prevalence of obesity explains this trend, the benefits seen in patients also encourage surgeons to offer this solution. And this recent study provides new arguments in favour of bariatric surgery.

A reduced risk of a third party

The doctors of the university of Cincinnati have studied the data of health of over 22 000 obese patients and operated more nearly 66 500 obese subjects not operated on. This information was collected between 2005 and 2012 in several states in the u.s., and patients were monitored until 2014. More than 80 % of the volunteers in the study were women.

The analysis reveals that patients who have undergone placement of a gastric band, bypass or removing part of the stomach were 33 % less likely to suffer from cancer than the others.
