Overview
Gastrointestinal stromal tumor (GIST) is a disease in which abnormal cells form in the tissues of the gastrointestinal tract. GISTs may be malignant (cancer) or benign (not cancer). They are most common in the stomach and small intestine but may be found anywhere in or near the GI tract. It is thought that GISTs begin in cells called interstitial cells of Cajal (ICC), which are located in the wall of the GI tract.

Who is at highest risk?
Age and genetic factors can increase the risk of having a GIST. Individuals in the age group of 50-80 years are believed to be at the highest risk. The risk of GIST is also increased in people who have inherited a mutation (change) in a certain gene. These mutations can predispose an individual to an increased risk of GIST. Such conditions include Neurofibromatosis type 1, Carney-Stratakis syndrome and Familial gastrointestinal stromal tumor syndrome. In rare cases, GISTs can be found in several members of the same family.
