When is brain tumour surgery recommended for glioblastoma?

Glioblastoma can grow into nearby brain tissue, so the aim is often the safest useful removal rather than removing tissue at any cost. Scans, symptoms, the tumour’s position, and the person’s strength and preferences help the neurosurgical team judge whether surgery is suitable. A tissue sample can confirm the diagnosis and guide tumour testing. Surgery may be followed by other treatments, and an operation does not by itself remove every tumour cell.

Ask for a review by a neurosurgeon and oncology team. Bring scan reports, medication details, and information about seizures, weakness, speech changes, memory, or changes in behaviour. Discuss the planned procedure, possible effects on movement or communication, recovery support, and how surgery fits with radiotherapy or medicines. If surgery is not suitable, ask which biopsy or non-surgical options could provide diagnosis or symptom control.

Seek emergency help for a first seizure, a seizure that does not stop, sudden weakness, new trouble speaking, severe drowsiness, repeated vomiting, or a rapidly worsening headache. These symptoms need prompt assessment and should not wait for a routine surgical appointment.

What is the main goal of surgery in this case? Which brain functions are near the tumour? Would tissue testing change the treatment plan? What warning signs should prompt urgent help after the operation?
