    What is the definition of Gastrointestinal Stromal Tumor?

    A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine. This type of tumor is thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells. Affected individuals can develop one or more tumors. GISTs are usually found in adults between ages 40 and 70; rarely, children and young adults develop this type of tumor.
