Type 2 Diabetes Raises Adenoma Risk in Those 40 to 49 Years of AgeThursday, May 24, 2012
People in their forties who have type 2 diabetes should have a colonoscopy to screen for colorectal cancer, recommend Washington University in St. Louis researchers. In a recent study they found that people in their forties who have type 2 diabetes have a similar rate of adenoma as people in their fifties, when colon cancer screenings typically begin. Previous studies have shown an increased risk of colorectal cancer and polyps with diabetes. This study compared the results of colonoscopies performed over six years conducted in three groups of people who were referred for a colonoscopy because of pain or bleeding; those in their forties with diabetes, those in their forties without diabetes, and those in their fifties without diabetes. They found that people in their forties with diabetes had a similar rate of adenoma detection (30.4 percent) as those in their fifties without diabetes (32 percent), and nearly twice as high as the detection rate in those in their forties without diabetes (14.4. percent). The researchers note the findings suggest reviewing current colorectal screening guidelines for people who have type 2 diabetes.
