Gastrointestinal Stromal Tumors (GIST)
What is GIST?
These rare tumors start in very early forms of cells in the wall of the gastrointestinal (GI) tract, also known as the digestive tract. Although GISTs can be found anywhere in the digestive tract, most are found in the stomach. These tumors start in very early forms of special cells in the part of the nervous system that regulates body processes such as digesting food.
More than half of GISTs start in the stomach. Most of the others start in the small intestine, but GISTs can start anywhere along the GI tract. Some GISTs are more likely to spread to other parts of the body than others. Your doctors will look at factors that are unique to you, such as how large the tumor is, where it's located in the GI tract, and how fast the tumor cells are dividing.
