Radiation therapy is the most common treatment for neuroendocrine tumors, but is also often used along with other treatments like surgery or chemotherapy. Your doctor may advise radiation to:
- Serve as the main treatment, sometimes along with chemotherapy.
- Shrink a tumor to make it easier to operate on before surgery.
- Kill any remaining tumor cells following a surgery.
- Relieve symptoms such as pain, bleeding, trouble swallowing, cough, or problems caused by the tumor spreading.
- External beam radiation therapy. This treatment is the most common type of radiation therapy used to treat neuroendocrine tumors. This treatment focuses radiation from outside the body on the tumor in order to eliminate tumorous cells.
