Insulinomas: Benign Pancreatic Tumors

10. Multiple Endocrine Neoplasia Type 1 (MEN1)

MEN1 is a genetically inherited condition consisting of a group of disorders that affect the endocrine system, the collection of organs that release hormones into the bloodstream. The pancreas is one of these organs. People with MEN1 have genetic changes that put them at a higher risk of developing insulinomas, and about 5% of them develop insulinomas. People with this condition tend to be younger when they get the tumors than those without MEN1, and they are more likely to have multiple growths that recur.
