What is Stereotatic Radiosurgery?
Stereotatic Radiosurgery (SRS) is a highly targeted and focused radiation treatment which delivers extremely high doses of radiation directly to the target to destroy it.
The term stereotactic is a term used in Neurosurgery to refer to the ability to accurately identify a point in 3-dimensional space. Radiosurgery uses technology used in neurosurgery to destroy the tumour. For more technical details, please see here.

Today, Frameless Radiosurgery is possible with modern navigational techniques such that patients no longer need to have a metal frame screwed into their skull for accurate targeting
Modern digital navigation achieves sub-mm accuracy
Understanding the difference between Surgery and Radiosurgery
Surgery involves physically cutting through tissue and bone to reach the tumor so as to remove it from the body.
Radiosurgery does not involve any cutting at all. The name was given because after destroying the tumor with high doses of focused radiation, the body automatically removes the dead cells, and the cure rate is as if surgery was done
Breast Cancer Brain Metastasis
- before SRS
Complete response 3 months after SRS
Spine Metastasis strangulating the spinal cord and compressing the surrounding thecal sac.
6 months after SRS, tumor has shrunk and the the spinal cord is no longer compressed. Patient no longer has pain and weakness
It is completely painless, bloodless and is done as an outpatient procedure.
Patient does not need to undergo open surgery and does not suffer from operation risks
