Radiation Oncologist
A Radiation Oncologist uses ionizing radiation and other modalities to treat malignant and some benign diseases. Radiation Oncologists may also use computed tomography (CT) scans, magnetic resonance imaging (MRI), ultrasound, and hyperthermia (heat) as additional interventions to aid in treatment planning and delivery. Training required is five years: one year of general clinical work, followed by four years of dedicated Radiation Oncology training.
