Does radiotherapy treat glioma?

Glioma is a broad group of brain and spinal cord tumours. Some grow slowly and may be monitored or treated with surgery, while others need active treatment. Radiotherapy may be used after surgery, alongside medicines, when a tumour remains, or when surgery is not suitable. The team considers the tumour’s position, molecular features, symptoms, imaging, and the person’s general health.

A radiation oncologist uses scans to shape treatment around the target and reduce exposure to sensitive brain structures. Effects can include tiredness, skin or scalp changes, hair loss in the treatment field, headache, or difficulty thinking clearly. Some effects occur during treatment and others may appear later, so follow-up matters.

Take your scan reports, pathology information, medicine list, and a record of symptoms to the appointment. Ask whether observation, surgery, medicines, radiotherapy, or a combination is being considered, and why. Discuss how treatment could affect work, driving, concentration, seizures, and daily activities. Tell the team about pregnancy or the possibility of pregnancy before planning radiation.

Seek urgent advice for a new seizure, rapidly worsening headache, repeated vomiting, new weakness or numbness, confusion, fainting, or sudden changes in speech, vision, or balance. Emergency services are appropriate for a prolonged seizure, severe breathing difficulty, or someone who cannot be woken.

What type and grade of glioma do I have? What is radiotherapy intended to achieve? Would it be given before, after, or with another treatment? Which brain functions are near the target? How will side effects and follow-up be managed?
