Key Points about Radiation Oncology

  • Radiation therapy uses high-energy radiation to kill cancer cells by damaging their DNA.
  • Radiation therapy can damage normal cells as well as cancer cells. Therefore, treatment must be carefully planned to minimize side effects.
  • The radiation used for cancer treatment may come from a machine outside the body, or it may come from radioactive material placed in the body near tumor cells or injected into the bloodstream.
  • A patient may receive radiation therapy before, during, or after surgery, depending on the type of cancer being treated.
  • Some patients receive radiation therapy alone, and some receive radiation therapy in combination with chemotherapy.
