Interactions between aging, diabetes, obesity, and cancer. Obesity and advanced age are two risk factors for diabetes. Aging contributes to the development of diabetes due to physical inactivity, sarcopenia, which can cause insulin resistance and diabetes. In obesity, insulin resistance initially leads to hyperinsulinemia. Overtime, the pancreas is unable to continue to secrete sufficient insulin and decompensation occurs, leading to diabetes. Aging, diabetes, and obesity all contribute to carcinogenesis.
