Maintaining a healthy weight may be important for reducing the risk of gastrointestinal cancer, a new study suggests. The research adds to the evidence that excess weight and weight increases in adulthood increase the risk for colon and other gastrointestinal (GI) cancers. “In a time when obesity rates are rising globally and 70% of the U.S. population alone is considered overweight or obese, understanding the association between obesity and long-term disease risk, such as cancer, is critical for improving public health,” said study lead author Holli Loomans-Kropp, a cancer control researcher and epidemiologist with the Ohio State University Comprehensive Cancer Center, in Columbus. “Our study suggests that being overweight or obese during several phases of life can increase a person’s risk for gastrointestinal cancers in later adulthood,” she added in a university news release. A body mass index (BMI) that reached levels for obese or overweight in early, middle and late adulthood increased the risk of GI cancer. Frequent aspirin use did not change this increased risk in overweight and obese people. Obesity and overweight are linked to at least 13 types of cancer, according to the U.S. National Cancer Institute. For the new study, researchers evaluated previously collected data from more than 131,000 patients enrolled in the multicenter Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial between 1993 and 2001. Participants were aged 55… read on > read on >
