Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumors (GISTs) are a type of rare tumor that occurs in the digestive tract, most commonly in the stomach or small intestine. They originate from specialized cells called interstitial cells of Cajal, which are important for gut movement. GISTs can vary in size and behavior, ranging from benign to malignant. Symptoms may include abdominal pain, digestive issues, or bleeding. Treatment often involves surgery and targeted therapy, particularly if the tumor is cancerous. Early diagnosis is important for better outcomes, as GISTs can sometimes be resistant to conventional chemotherapy.
