Pancreatic cysts are fluid-filled growths that develop in the pancreas. This small glandular organ is located in the abdomen between the stomach and the intestines. In addition to making digestive enzymes, the endocrine (islet) cells in the pancreas produce hormones, such as insulin, that control blood sugar levels in your body.
