Radiotherapy

A type of treatment that uses ionizing radiation emitted by certain radioactive elements such as radium. When these rays pass through diseased tissue, they destroy abnormal cells or slow their development. Radiotherapy is used in several circumstances:

  • as the main means of treating certain cancers;
  • after a malignant tumor has been surgically removed to destroy the remaining cancer cells;
  • as a palliative treatment, to reduce the size of incurable cancer in order to relieve the patient. open next page to see More
