Both Diabetes and Cancer are prevalent diseases whose incidence are increasing and have a great impact on the health worldwide. Individuals with diabetes may have an increased risk of cancer. It has been observed that cancer and diabetes are diagnosed within the same individual more frequently than would be expected by chance.
People with diabetes are at undoubtedly higher risk for many forms of cancer. Diabetes, predominantly type 2 diabetes (non-insulin-dependent diabetes), has been associated to certain cancers, while prostate cancer occurs less often in men with diabetes. The risk for cancers of the liver, pancreas, and endometrium are about two fold or higher and lesser for cancers of the colon and rectum, breast, and bladder in individuals with diabetes. Other cancers (e.g., lung) are not associated with an increased risk in individuals with diabetes. In recent times developed glucose intolerance or diabetes may be a consequence of pancreatic cancer and that recent onset of glucose intolerance or diabetes may be an early sign of pancreatic cancer.
