About this approach
Stereotactic radiosurgery is a precisely planned form of radiation, not an operation with an incision. It delivers one or a small number of high-dose treatments to a defined target, most often in the brain and sometimes the spine. Gamma Knife, CyberKnife, and linear-accelerator systems are delivery platforms rather than separate cures.
Where it fits: Highly focused radiation for selected brain and spine targets
Where this treatment is used
SRS is established for selected brain metastases and some primary brain or benign tumors. Suitability depends on the number, size, location, symptoms, prior radiation, and the wider cancer plan. Whole-brain radiation, surgery, systemic therapy, or observation may be more appropriate in other situations.
Procedure and practical considerations
Risks include headache, fatigue, swelling, seizures, neurologic changes, and delayed radiation injury or necrosis. Steroids may be needed. Follow-up MRI findings can be difficult to distinguish from tumor growth and should be interpreted by an experienced team.
