Stereotactic radiosurgery (SRS) is a way to treat brain disorders. It uses highly focused beams of radiation to target specific areas of the brain. It can also be used on other parts of the body, such as the spine. The beams of radiation destroy the tissue that a neurosurgeon would have removed during an operation.

SRS is used to:

  • Stop cancerous and noncancerous tumor growth
  • Shrink cancerous and noncancerous tumors
  • Close off arteriovenous malformations (AVMs)—abnormal blood vessels that disrupt blood flow to the brain
  • Treat disorders such as:
