Pancreatic cancer occurs when cells within the pancreas begin to grow abnormally in an uncontrolled and invasive way.
The pancreas is an organ located behind and to the right of the stomach, near the liver, gall bladder, and intestine. The area of the pancreas on the right side of the body, closest to the first section of the small intestine, is called the “head” of the pancreas; the middle section, behind the stomach, is called the “body” of the pancreas; and the section on the left side of the body, closest to the spleen, is called the “tail” of the pancreas.

The pancreas is made up of two very different kinds of cells: endocrine cells and exocrine cells. The endocrine cells produce a number of different chemicals called hormones that enter the bloodstream and travel to other areas of the body to exert their effects. For example, the endocrine cells of the pancreas produce insulin, which breaks down and then uses or stores sugars from food.
The exocrine cells of the pancreas produce digestive juices that travel through a system of tubes called ducts into the first section of the intestine, the duodenum. These digestive juices contain enzymes that help process fat, protein, and carbohydrates in food, breaking them down into smaller units for better use by the body.
