Lifetime excess weight linked to colorectal cancer risk

Excess weight had a stronger impact on colorectal cancer risk than suggested in previous studies that did not consider cumulative lifetime exposure, according to a study published in JAMA Oncology.“Excess weight has long been recognized as a risk factor for colorectal cancer (and several other cancers), but risk estimates from essentially all previous studies were based on excess weight determined at one single point of time. We wanted to derive more accurate risk estimates by considering lifetime excess weight,” Hermann Brenner, MD, MPH, professor of epidemiology at HeidelbergRead More
