Treatment for bronchial neuroendocrine tumors depends on the size and location of the tumor, as well as the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, targeted therapy, and/or immunotherapy. Surgery is the most common treatment for bronchial neuroendocrine tumors, and may involve removing part or all of the affected lung. Radiation therapy and chemotherapy may be used to shrink the tumor before or after surgery. Targeted therapy and immunotherapy may also be used to help reduce the size of the tumor or slow its growth.
