Radiation Therapy

Radiation therapy is the use of high-energy particles or rays to damage cancer cells and prevent them from growing. Other names for radiation therapy include radiotherapy, x-ray therapy, and irradiation. Although some normal cells may be affected by radiation, the cells most susceptible to damage by radiation are fast-dividing cells such as those in the bone marrow and lining the digestive tract. Most normal cells appear to recover fully from the effects of the treatment.
