What Is Stereotactic Radiosurgery (SRS)?

Stereotactic radiosurgery (SRS) is an ultra-precise form of radiation that can treat abnormalities in the brain and spine. Stereotactic body radiotherapy (SBRT) treatments target tumors in other parts of the body that may be hard to reach. Both SRS and SBRT are precise and effective types of radiation treatments for cancer.

They use concentrated radiation beams in high doses to destroy tumors in hard-to-reach areas of the body.

It can deliver precisely-targeted radiation in fewer high-dose treatments than traditional therapy, which can help preserve healthy tissue.

Stereotactic Radiosurgery Benefits

Both SRS and SBRT:

  • Are noninvasive treatments.
  • Require no anesthesia or incisions.
  • Minimize radiation damage to surrounding healthy tissue and organs.

Compared to other cancer treatments, other benefits include:

  • Fewer treatments. Most people don't need more than five SRS treatment sessions.
  • Less risk. Because SRS is noninvasive, most people have fewer complications and side effects.
  • Greater access to more tumors. SRS technology gives us the ability to treat cancers anywhere in the body, including hard-to-treat tumors.
