Pancreatic cancer is the growth of cancer cells in the pancreas. The pancreas is a long, flattened pear-shaped organ in the abdomen. It makes digestive enzymes and hormones including insulin.
Cancer occurs when cells in the body divide without control or order. If cells keep dividing uncontrollably, a mass of tissue forms. This is called a growth or tumor. The term cancer refers to malignant tumors. They can invade nearby tissue and spread to other parts of the body.
