Women who are overweight or obese have up to twice the risk of developing colorectal cancer before the age of 50 as women who have what is considered a normal body mass index (BMI), according to a research led by Washington University School of Medicine in St Louis.

The researchers have collected detailed information on body weight throughout the life course, family and endoscopy histories, and lifestyle factors at study baseline and every two to four years. Up to 2011, doctors diagnosed 114 colorectal cancer cases under the age of 50.

“Our findings really highlight the importance of maintaining a healthy weight, beginning in early adulthood for the prevention of early-onset colorectal cancer,” said co-senior author and cancer epidemiologist Yin Cao, an assistant professor of surgery in the Division of Public Health Sciences at Washington University.

More studies are needed to uncover the best ways to identify young people at high risk of colorectal cancer at younger ages.

But for reasons that remain unknown, new cases of, and deaths due to, both colon and rectal cancers have been increasing for younger adults aged 20 to 49.
