“Gastrointestinal stromal tumor, GIST, is a relatively uncommon type of cancer that occurs in the gastrointestinal tract. GIST’s belong to a class of diseases called sarcomas. Experts estimate that 4,500 to 6,000 GIST’s are diagnosed each year in the United States. GIST’s can develop anywhere in the GI tract but occur most often in the stomach (approximately 60%).”
