WebRadiation Therapy for Pituitary Tumors Radiation therapy for pituitary tumors involves sending beams of radiation from an external machine, through the skin and skull toward the tumor. When the beams of radiation reach the tumor, they can destroy the tumor cells by damaging their DNA. WebRadiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cells can also be …
