Gastrointestinal stromal tumors, or GISTs, are tumors that grow in the tissues of the gastrointestinal (GI) tract. The GI tract includes the:
- Esophagus
- Stomach
- Small intestine
- Large intestine
Together these organs help digest and draw nutrients from food. Generally, GIST tumors affect either the stomach or the small intestine.

GIST Risk Factors
We often don’t know why certain people develop GIST. In some cases, though, risk factors can increase your chances of developing this disease. The primary risk factor for GIST is genetics, meaning that the cancer can run in families. Certain genetic syndromes may also be GIST risk factors, including:
- Neurofibromatosis type 1
- Carney triad
Make sure to discuss with your doctor your chances of developing GIST if you have any of these risk factors.
GIST Symptoms
Most patients with GIST do not have any specific symptoms. GIST symptoms are common to a variety of different problems. Check with your doctor if you experience any of the following:
- Blood in your vomit or stool
- Severe stomach pain
- Painful swallowing
- Your stomach feels full even after eating just a small amount
- Fatigue
