Studies reveal that diabetes and high insulin levels can increase the risk of various types of cancer. Diabetes can also put you at a risk of a wide range of health conditions like glaucoma, kidney disease and stroke. According to a study by the American Institute for Cancer Research, diabetics have a higher than average risk to develop kidney, pancreatic and colorectal cancer. Sources reveal that diabetes increases the risk of colorectal, breast, and bladder cancer by 20% to 50%. But it cuts men’s risk of prostate cancer.
There’s no definitive answer to whether diabetes treat cancer risk or not. Metformin, the most commonly used diabetes drug, seems to lower cancer risk. But there’s also evidence from some studies contradicted by others that insulin, particularly long-acting insulin glargine (Lantus), may increase cancer risk, reports Webmd. Various researchers say that maintaining a healthy plant-based diet can help prevent diabetes. The cancers with increased risk in Type 1 diabetes include stomach and cervical cancer.
