The association between diabetes and cancer was first noted over 100 years ago, but physicians have become increasingly aware of this association only in the last few years as recent studies have demonstrated that having diabetes increases the risk of almost all types of cancer. The risk of pancreatic, liver, and endometrial cancer is approximately twice that of the non-diabetic population. Some studies have reported a similar increase in the risk of bladder cancer and in cancers of the oral cavity.
