- pancreatic tumor
- listen (PAN-kree-A-tik TOO-mer)
- A tumor that forms in the cells of the pancreas. The two main types of pancreatic tumors are pancreatic exocrine tumors and pancreatic neuroendocrine tumors. Most pancreatic cancers are exocrine tumors, which form in cells that make enzymes to help the body digest food. Pancreatic neuroendocrine tumors form in neuroendocrine pancreas cells (such as islet cells). These cells make hormones that help control sugar levels in the blood. Pancreatic neuroendocrine tumors may be benign (not cancer) or malignant (cancer). They are much less common than pancreatic exocrine tumors and have a better prognosis.
