Radiation oncologists are the doctors who will oversee your radiation therapy treatments. These physicians work with the other members of the radiation therapy team to develop your treatment plan and ensure that each treatment is given accurately. Your radiation oncologist will also monitor your progress and adjust the treatment as necessary to make sure the radiation is hitting its target while minimizing side effects. Before, during and after your radiation therapy treatments, your radiation oncologist works closely with other cancer doctors, such as medical oncologists and surgeons, to maximize the radiation's effectiveness.
