Stereotactic Radiosurgery
Non-surgical radiation treatment delivering high precision for brain tumors and lesions.
What is SRS?
Stereotactic Radiosurgery (SRS) is a highly advanced, non-invasive radiation therapy that delivers precisely-targeted radiation at much higher doses, in only a single or few treatments, compared to traditional radiation therapy. Despite its name, SRS is not surgery — there is no incision. It uses multiple beams of radiation converging in 3D to treat tumors and other conditions in the brain with extreme accuracy. The treatment is so precise that it can target tumors while preserving cognitive function and sparing nearby healthy brain tissue.
Benefits of SRS
- ✓ Non-invasive alternative to traditional brain surgery
- ✓ Sub-millimeter accuracy in targeting
- ✓ Completed in 1 to 5 sessions typically
- ✓ Minimal damage to surrounding healthy brain tissue
- ✓ Quick recovery with no surgical incision, bleeding, or infection risks
How SRS Works
SRS uses specialized equipment to focus many small beams of radiation on a precise target from multiple angles. While each individual beam is too weak to damage the tissue it passes through, the point where all beams intersect receives a massive, ablative dose of radiation. Advanced imaging and precise head fixation ensure sub-millimeter accuracy.

Frequently Asked Questions
Is Stereotactic Radiosurgery actually surgery?
No, despite the word 'surgery' in its name, SRS is a completely non-invasive radiation treatment. There are no incisions, no anesthesia required, and no hospital stay.
Will I lose my hair after SRS?
Unlike whole-brain radiation, hair loss with SRS is very rare and only occurs in a small patch exactly where the radiation enters the scalp, if at all.
How quickly can I return to normal activities after SRS?
Most patients can return to their normal daily activities within 1 to 2 days after the procedure. There is virtually no recovery time needed.
How long does it take for the tumor to shrink?
SRS damages the DNA of the tumor cells so they can no longer reproduce. The tumor may shrink over several months, or simply stop growing entirely.
