Radiation therapy uses special equipment to deliver high doses of radiation (beam of x-rays) to cancerous tumours, to kill or damage them so they cannot grow or spread. Normal cells may be affected by radiation, but most appear to recover fully from the effects of the treatment. Radiation therapy affects only the tumour and the surrounding area. Some cancers are very sensitive to radiation but not all.
Radiotherapy is usually given in small doses over a period of time; this is known as a course. A doctor who manages your radiotherapy is called a radiation oncologist.
Auckland Oncology does not offer Radiotherapy and will refer patients who may require this treatment.
