Radiation Therapy for Cancer: How Does It Work? - Cleveland Clinic
2022年9月7日 · Radiation therapy, along with chemotherapy and surgery, is one of the most powerful tools we use to treat cancer. Radiation therapy includes the most common type, external beam radiation therapy (EBRT), and internal radiation therapy. Your radiation oncologist can recommend radiotherapy tailored to your condition and the kind of cancer you have.
How Radiation Therapy Is Used to Treat Cancer
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells.
