Chemotherapy uses anti-cancer (cytotoxic) drugs to destroy cancer cells. Cytotoxic means toxic to cells. These drugs affect the way cancer cells grow and divide, but they also affect normal cells.
Chemotherapy may be given:
- with radiotherapy or on its own, to treat a high-grade (grade 4) glioma
- if a brain tumour comes back after surgery and radiotherapy
- after surgery instead of radiotherapy, if a low-grade glioma has not been completely removed.
Chemotherapy may be the main treatment for a lymphoma that starts in the brain, called a CNS lymphoma.
