"The treatment of brain metastases depends on many factors, such as the tumor of origin, the number and location of lesions within the brain and the extent of cancer in places other than the brain.
Surgery: If there is only one tumor and the patient's overall condition is good, surgical removal of the metastasis may be attempted, although location, duration and metastases should be considered
Gamma knife: This is a type of radiation treatment delivered by a machine that focuses multiple radiation beams directly at the involved area.
Radiation therapy: In patients with more than one brain metastasis, surgery is not usually an option and radiation is delivered to the entire brain"
