radiosurgery
Focused radiation treatment
Radiosurgery is a medical procedure that uses precisely focused beams of radiation to treat tumors and other abnormalities in the brain or body.
Despite the name, no incision is made—the "surgery" is performed by concentrated radiation that destroys targeted tissue while sparing surrounding areas.
The tumor was treated with radiosurgery rather than conventional surgery.
