When is radiotherapy recommended for brain tumour?

The team considers the tumour’s type, grade, position, size, growth pattern, and relationship to important brain structures. Radiation may target the area after an operation if tumour cells could remain. It can also be chosen when surgery would carry substantial risk, or when a tumour has returned or spread within the brain or its coverings.

Some plans use carefully shaped radiation over an area, while others use a focused approach for a small, clearly defined target. Treatment may be combined with surgery or medicines. Planning scans help the team protect healthy brain tissue as far as possible, but effects can vary with the treated area.

Bring a list of medicines, including steroids and anti-seizure treatment, and mention any seizures, headaches, vision changes, balance problems, or previous radiation. Ask whether you will need help travelling home after visits and whether fatigue could affect work, driving, or caring responsibilities.

Take medicines exactly as prescribed and report new symptoms rather than stopping treatment yourself. Keep follow-up appointments, because the team may use examinations and scans to assess the response and manage side effects.

Seek urgent help for a first seizure, a seizure lasting longer than usual, sudden weakness, new trouble speaking, severe confusion, repeated vomiting, or a rapidly worsening headache. Call emergency services if someone is unconscious, has breathing difficulty, or does not recover normally after a seizure.

Ask what the radiation is targeting, why it is recommended now, whether surgery or medicines are also needed, how treatment could affect memory or other brain functions, and which symptoms require same-day advice.
