A consensus report published by the American Diabetes Association and the American Cancer Society indicates a link between diabetes and some kinds of cancer. Diabetics have at least twice the risk of liver, pancreatic and endometrial cancers than non-diabetics. The possible mechanisms for these associations are not yet well understood.
PositiveTip: Cancer risk should not deter treatment in most patients. Most diabetics will benefit by physical activity, weight loss, and a healthy diet–all of these tend to lower cancer risk!
