In patients found to have subepithelial mass ...
The only known risk factors for gastrointestinal stromal tumors (GISTs) − older age and certain rare, inherited genetic syndromes – cannot be changed. There are no known lifestyle-related or environmental causes of GISTs, so at this time we do not know of any way to protect against these cancers.
Gastrointestinal stromal tumors (GISTs) form in the walls of the gastrointestinal tract, predominantly in the stomach or small intestine. Learn who's at risk, what causes these tumors, and common ...

GISTs are often found during an endoscopy or CT scan for an unrelated condition.
