Radiosurgery is an ultra precise form of radiation therapy. It is a non-surgical, non-invasive procedure that uses highly focused x-rays to treat tumors. The treatment involves the delivery of high-dose radiation beams that converge on a specific area of the brain or body where the abnormality resides. It distorts the DNA of tumor cells so they lose their ability to reproduce.

Following treatment, benign tumors usually shrink over a period of 18 months to two years. Malignant and metastatic tumors may shrink more rapidly, even within a couple of months.

Treatment is delivered in just one to five total treatments. Radiosurgery is usually performed on an outpatient basis. Radiosurgery treatments are similar to having an x-ray. There is no pain or discomfort from the actual procedure.

Our Institute for Radiosurgery has more experience with body radiosurgery than any other facility in the region. The Institute’s highly skilled radiation oncologists, physicists, and certified radiation therapists are part of our multidisciplinary cancer care team.

Tumors Treated

The most common types of tumors treated with radiotherapy include:

  • Cancerous and benign tumors of the brain
  • Tumors of the lung, liver, pancreas, or kidney
  • Spinal tumors
  • Tumors within an area that has previously received radiation


  • No invasive surgery
  • No halos (In most cases, a frameless system is used.)
  • Potentially no side effects
  • Unparalleled precision
  • Fewer interruptions to life than occur from standard treatments
  • Minimal preparation
