Radiation oncologists work with surgeons, medical oncologists, and other doctors to find out the most appropriate treatment for cancer. Before performing radiation therapy, radiation oncologists use certain software to map out the location where the radiation will be delivered to their patients.

Radiation oncologists can use various methods for cancer treatment, including external beam radiotherapy, modality therapy, radioactive implantations, and hyperthermia. Planning plays a major role in cancer treatment. They keep an eye on the overall health of cancer patients and establish long-term relationships with patients post-treatment.
