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.

Symptoms of pancreatic cancer are often shared with other illnesses and frequently do not appear until the disease has reached an advanced stage. Common symptoms include:12

Abdominal pain: This is a frequent symptom, which often radiates to the back.13
Unexplained weight loss: A common indicator of the disease.13
Digestive issues: Patients may experience difficulty digesting fatty foods.14
Metabolic changes: Problems with sugar metabolism or glucose regulation may occur.14
Jaundice: As a tumor grows, it may block the common bile duct, leading to a buildup of bilirubin. This results in jaundice, characterized by the yellowing of the skin and eyes.13
Enlarged gallbladder: A blockage of the bile duct can also cause the gallbladder to become enlarged.1

Because these symptoms are often subtle or absent in the early stages, early detection remains a significant challenge for patient survival.2
