Radiotherapy uses ionising radiation (from X-rays, electron beams or gamma rays) to kill tumour cells.
Radiotherapy is generally used as part of a multi-modality approach to cancer treatment. It can be the primary cancer treatment, or it can be used along with surgery and/or chemotherapy. It is used for both curative and palliative treatment.
In Victoria, the majority of radiotherapy services are provided by the public healthcare sector.
