Gastrointestinal Stromal Tumors (GIST)

Did You Know?
More than half of all GIST tumors are found in the stomach. Other places where GISTs may develop include the small intestine, the esophagus, the rectum, and the colon.

Gastrointestinal stromal tumors are soft tissue sarcomas that form in soft tissues of the gastrointestinal tract, usually in the stomach or small intestine. They are most common in adults, and may be benign (not cancer) or malignant (cancer). Gastrointestinal stromal tumors often do not cause early symptoms.
