A Radiation Oncologist is a medical specialist doctor with training in the use of radiation therapy (also called radiotherapy) to cure or reduce the symptoms of cancer, and in the overall care of cancer patients. They are ultimately responsible for assessing individual patients, determining the best management plan, overseeing treatment and assessing progress. Radiation Oncologists may order tests and images, prescribe medications, and consult with other doctors involved with cancer treatment. Radiation Oncologists work closely with Radiation Therapists and Radiation Oncology Medical Physicists to ensure that the treatment is safe and accurate. After treatment, ongoing follow-up by the Radiation Oncologist is common, in helping to assess the patient’s response to treatment and manage any further developments in the care of the patient.
