Nov. 1, 2005 A new study confirms that patients with diabetes are significantly more likely to have colon cancer than individuals without diabetes. Researchers at the Medical University of South Carolina reported results from a large cross-sectional analysis assessing the risk of colon cancer among patients with diabetes at the 70th Annual Scientific Meeting of the American College of Gastroenterology.
Researchers analyzed data from a comprehensive nationally representative sample of patients using the 1997-2003 National Health Interview Survey. Of the 226,953 patients in the study, 5.9 percent had a history of diabetes. Researchers controlled for age, race, gender, obesity, alcohol use, tobacco use, and physical activity. Adjusting for potentially confounding factors, researchers found that people with diabetes were 1.4 times more likely to have colon cancer as individuals without diabetes.
"This work is important because it suggests that people with diabetes may be at higher risk of colon cancer. Until we know for sure, diabetics should pay particular attention to their doctor's recommendations for colorectal screening," said Donald Garrow, M.D. one of the investigators.
