Definition
VIPoma is a very rare type of cancer that usually grows from certain cells in the pancreas.
Overview, Causes, & Risk Factors
VIPoma causes cells in the pancreas to produce high levels of a hormone called vasoactive intestinal peptide (VIP). This hormone increases secretions from the intestines and relaxes some of the smooth muscles in the GI system.
The cause is not known.
VIPomas are usually diagnosed in adults, most commonly at age 50. Women are more likely to be affected than men. This cancer is rare, affecting an estimated 1 in 10 million people per year.
