An anatomical illustration of the human pancreas shows its location near the stomach and intestines, a detailed cross-section highlighting ducts and the islet of Langerhans, and an inset of pancreatic tissue histology with labeled alpha, beta, and delta cells. — pancreatic cancer The human pancreas is composed of two main types of tissue: acinar cells and islets of Langerhans. The acinar cells produce digestive enzymes, which are secreted into tiny ducts that feed into the pancreatic duct. Islets of Langerhans are clusters of cells that secrete hormones such as insulin and glucagon directly into a capillary network, which also joins the pancreatic duct.

Central obesity, characterized by the accumulation of fat primarily around the abdomen, is a significant risk factor for pancreatic cancer. In some postmenopausal women, this condition can increase the risk of developing the disease by as much as 70 percent.1

The link between central obesity and pancreatic cancer is associated with two primary physiological changes:
* Increased Insulin Levels: Central obesity is linked to elevated levels of insulin in both men and women.1
* Metabolic Disruption: The condition is associated with the disruption of normal endocrine and metabolic functions.1

While these associations are well-documented, the specific biological mechanism by which these metabolic dysfunctions and high insulin levels lead to the development of pancreatic cancer remains unclear. Maintaining a healthy weight and addressing metabolic health are important considerations for reducing cancer risk, as obesity is a modifiable factor that significantly impacts long-term health outcomes.1
