Increased glucose level is a strong risk factor for colorectal cancer

Diabetes is a very common illness that affects more than 20 million people in the U.S. and it is estimated an additional 54 million Americans have pre-diabetes, a condition that occurs when a person's blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes. Therefore, it is important to determine whether glucose and insulin levels are associated with a higher risk of colon polyps, the precursor lesions to colon cancer.
