Radiation Oncology is a medical specialty that involves using radiation therapy to treat cancer. Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to damage the DNA of cancer cells and prevent them from growing or dividing. The goal is to destroy the cancer cells while minimizing harm to healthy tissue. Radiation oncologists work closely with other members of a patient's care team, including medical oncologists, surgeons, and radiologists, to develop personalized treatment plans for each patient. They may also work in conjunction with nuclear medicine physicians who specialize in diagnostic imaging using radiation.
