The surgical procedure group had lower than half as many instances of most cancers.
“We did see a distinction in breast most cancers, colon most cancers, liver most cancers, and ovarian most cancers incidence … with sufferers within the bariatric surgical procedure group having decrease incidence of those 4 kinds of cancers when in comparison with the non-surgical management group,” mentioned Vibhu Chittajallu, MD, lead examine creator and a gastroenterology fellow at College Hospitals in Cleveland.
