Type 2 diabetes, insulin use linked to colorectal cancer in men

Washington, Oct 19 (ANI): A new study has revealed that type 2 diabetes mellitus is associated with colorectal cancer (CRC) among men.

Hyperglycemia and hyperinsulinemia, which are especially pronounced during the early stages of type 2 diabetes, have been proposed as mediators for the association between CRC and type 2 diabetes.

Although it is known that type 2 diabetes is associated with an increased risk of CRC, it is not clear if this association varies by gender or other factors.

"While our study supports an association of type 2 diabetes with colorectal cancer incidence among men, our results also suggest that insulin use is associated with a slight, but not a substantially increased, risk of colorectal cancer among men with type 2 diabetes," said Peter T. Campbell, lead author of this study.

"Prevention strategies should emphasize adherence to guidelines intended for the general population such as smoking cessation, weight management, exercise and regular early detection exams," the author said.

Among men, type 2 diabetes was associated with increased risk of incident CRC compared to not having type 2 diabetes. CRC risk was higher for those participants with type 2 diabetes regardless of whether or not they used insulin.

Among women, type 2 diabetes and insulin use were not associated with CRC risk.

The study appears in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. (ANI)
