Stereotactic radiosurgery (SRS)
High-precision radiation delivered in a single or few sessions for small lesions.
SRS (Gamma Knife, CyberKnife, linac-based) delivers precise high-dose radiation in 1-5 sessions. Used for brain metastases, vascular malformations, and small tumors.
What this means for you: SRS is an alternative to surgery for some small brain lesions. Consult both neurosurgery and radiation oncology for treatment options.
