Radiotherapy treats cancer by using high-energy rays to destroy the tumour cells, while doing as little harm as possible to normal cells. Newer ways of giving radiotherapy to the brain are designed to limit the damage to healthy brain tissue.
We have more detailed information on radiotherapy.
Radiotherapy can be given:
- as your main treatment
- after surgery if a tumour cannot be completely removed
- after surgery to reduce the risk of the tumour coming back
- with chemotherapy if you have a high-grade glioma
- if a tumour comes back.
