What to expect from radiotherapy for glioma

The radiotherapy team reviews your scans, biopsy information and any surgery before designing the treatment field. A mask or head support helps you remain still. At visits, the machine delivers radiation from different angles while you lie on the treatment couch. Staff leave the room briefly but monitor and communicate with you throughout.

Effects differ by the part of the brain treated and by the medicines used alongside radiation. Fatigue, scalp irritation, hair loss in the treatment area, headache and nausea are possible. Some people notice concentration, memory, balance or mood changes from the tumour or treatment; report changes rather than assuming they will pass.

Take prescribed medicines on the schedule given, bring questions to review appointments, and tell staff about new neurological symptoms. Use gentle scalp care and protect the treated area from sun and friction. Plan transport and lighter tasks if fatigue or medication affects alertness. Ask about physiotherapy, speech therapy, occupational therapy or practical support when daily activities become harder.

Call your team for worsening headaches, persistent vomiting, increasing sleepiness, a new seizure, fever, or a change in movement, speech, vision or coordination. Seek emergency help for sudden severe weakness, loss of consciousness, severe confusion, a prolonged seizure or breathing difficulty. Follow the written emergency instructions from your treatment centre.

Ask what type and grade of glioma is being treated, how the target was selected, whether another treatment is planned, and which changes should be reported the same day. Ask when scans will be reviewed and what rehabilitation or home support is available.
