 For patients who have one or two metastases in the brain, the tumors can often be removed with surgery to relieve symptoms from the tumors and to improve survival. However, about half of all patients who have the tumors removed with surgery will develop regrowth recurrence of the tumor. To prevent this regrowth of tumor, some patients receive radiation to the entire brain whole brain radiation after surgery. This involves daily treatment for about two to three weeks, and may cause long-term neurological problems, such as memory loss.
