Radiation therapy (radiotherapy) involves the use of high energy X-rays, to destroy and prevent the regrowth of cancer cells. If radiation is part of your treatment plan, it usually takes place after surgery or chemotherapy and will take place at an offsite regional cancer centre. You will be under the care of a radiation oncologist and your team at North York General Hospital will take care of the referral.
