What is SBRT (Stereotactic Body Radiotherapy)?

By

Updated October 03, 2012

Definition:

SBRT (stereotactic body radiotherapy) is a new procedure for treating lung cancer that uses high doses of radiation delivered to a precise target. By using special positioning and implanted markers in the body, radiologists are able to deliver a much higher dose of radiation to a cancer than traditional radiation therapy, while sparing healthy tissue.

With lung cancer, SBRT, is typically used for small lung cancers in patients who are unable to have surgery, either due to the location of the tumor or other health conditions that could make surgery risky.

Also Known As: stereotactic radiotherapy, stereotactic radiosurgery, stereotactic radiation therapy
