What Is KIT+ GIST?
A gastrointestinal stromal tumor (GIST) is a rare type of cancer primarily found in the gastrointestinal (GI) tract. GIST may develop anywhere in the GI tract, from the esophagus all the way to the colon, but most often grows in the stomach or the small intestine in the tissue between muscle layers.
While many of the more common types of cancer are known as carcinomas, KIT+ GIST belongs to a group of cancers called sarcomas. KIT+ GIST is a rare disease that can occur in people of any age, though it mainly affects those over the age of 50.
Although KIT+ GIST is a rare cancer and can be difficult to diagnose, treatment options are available.
