View in Spanish: Tumor de páncreas que produce insulina

Pancreatic insulin-producing tumor (PAN-kree-A-tik IN-suh-lin-proh-DOO-sing TOO-mer)
An abnormal mass that grows in the beta cells of the pancreas that make insulin. Pancreatic insulin-producing tumors are usually benign (not cancer). They secrete insulin and are the most common cause of low blood sugar caused by having too much insulin in the body. Also called beta cell neoplasm, beta cell tumor of the pancreas, and insulinoma.
