[Does bariatric surgery reduce cancer risk?]

Abstract

Obesity affects about 15 % of the French population, and is associated with numerous morbidities, including some cancers. In this context the diagnosis of cancer is a frequently more delayed, and with higher mortality. Methods of restrictive or malabsorptive bariatric surgery were largely developed for the treatment of severe or morbid obesity, and have significant benefits not only in terms of weight, but also on the cardiometabolic profile. Moreover, it seems that bariatric surgery, in a weight-dependent or - independent manner, exerts a favorable effect on the incidence and mortality of cancer.
