High insulin levels directly linked to pancreatic cancer

The first detailed explanation of why people with obesity and Type 2 diabetes are at an increased risk of pancreatic cancer has been published. The research demonstrates that excessive insulin levels overstimulate pancreatic acinar cells, which produce digestive juices. This overstimulation leads to inflammation that converts these cells into precancerous cells. The researchers say the findings may have implications for other cancers associated with obesity and Type 2 diabetes, where elevated insulin levels may also play a contributing role in disease initiation.
