How do you remove a GIST tumor?

Surgery for small GISTs

If the tumor is small, it often can be removed along with a small area of normal tissue around it. This is done through a cut (incision) in the skin. Unlike many other cancers, GISTs almost never spread to the lymph nodes, so removing nearby lymph nodes is usually not needed.

Do GIST tumors return?

A person who received treatment for a GIST is typically seen by the doctor every 3 to 6 months for up to 5 years and then once a year after that. This follow-up care is important because there is always a risk that the tumor could come back, even many years after surgery.

What happens when a GIST tumor ruptures?

Bleeding into the peritoneal cavity because of a ruptured GIST can engender acute abdominal pain, presenting a surgical emergency.
