Pancreatic cancer begins in the tissues of your pancreas — an organ in your abdomen that lies behind the lower part of your stomach. Your pancreas releases enzymes that aid digestion and produce hormones that help manage your blood sugar.

Several types of growths can occur in the pancreas, including cancerous and noncancerous tumors. The most common type of cancer that forms in the pancreas begins in the cells that line the ducts that carry digestive enzymes out of the pancreas (pancreatic ductal adenocarcinoma).

Pancreatic cancer is seldom detected at its early stages when it’s most curable. This is because it often doesn’t cause symptoms until after it has spread to other organs.

Symptoms

Signs and symptoms of pancreatic cancer often don’t occur until the disease is advanced. They may include:

• Abdominal pain that radiates to your back
• Loss of appetite or unintended weight loss
• Yellowing of your skin and the whites of your eyes (jaundice)
• Light-colored stools
• Dark-colored urine
• Itchy skin
• New diagnosis of diabetes or existing diabetes that’s becoming more difficult to control
• Blood clots
• Fatigue
