“It is a very large population-based study on obesity with 40 years follow up,” said Anton Bilchik, MD, PhD, surgical oncologist and division chair of general surgery at Providence Saint John’s Health Center and chief of medicine and Director of the Gastrointestinal and Hepatobiliary Program at Saint John’s Cancer Institute in Santa Monica. “It is an important study because it distinguishes obesity into two groups. Most studies do not. Not all obese patients have metabolic derangements. This study demonstrates that obese patients with metabolic derangements have an even higher risk of getting several cancers.”
