Glucagonoma
Definition
Glucagonoma is a very rare tumor of the islet cells of the pancreas, which release the hormones insulin and glucagon.
Overview, Causes, & Risk Factors
Glucagonoma is usually cancerous (malignant). The cancer tends to spread and get worse. This cancer affects the islet cells of the pancreas. As a result, they produce too much of the hormone glucagon. The cause is unknown, but genetic factors play a role in some cases. A family history of multiple endocrine neoplasia type I (MEN I) is a risk factor.
