What should you know about small glioblastoma?

Glioblastoma develops from cells in the brain and can affect nearby healthy tissue even when the visible area is small. An MRI describes its position, appearance and relationship to important brain structures. A biopsy or tissue removed during surgery helps confirm the diagnosis and provides information about the tumour’s biology.

Symptoms depend more on location and swelling than on size alone. They may include headaches, seizures, changes in speech, weakness, vision problems, memory changes or altered behaviour. A small lesion can still cause a major symptom if it lies in a critical area.

Your team may discuss brain tumour surgery to obtain tissue or remove as much visible tumour as safely possible. Radiotherapy and chemotherapy may follow surgery or be used when surgery is not suitable. The plan takes account of the tumour’s location, your neurological function, overall health and molecular test results. Ask about rehabilitation, seizure treatment, steroid use for swelling and practical support at home. Clinical trials may be discussed when an appropriate option is available.

Get emergency help for a first seizure, a seizure lasting longer than usual, sudden weakness on one side, new trouble speaking, severe confusion, loss of consciousness or a rapidly worsening headache with vomiting. Tell your team promptly about increasing drowsiness, repeated falls, new vision changes or a noticeable change in personality.

Where is the tumour and which functions could it affect? Do I need surgery for diagnosis, treatment or both? What did the tissue and molecular tests show? How will radiotherapy or chemotherapy fit into the plan? What symptoms should trigger an urgent call, and what support is available for memory, movement or speech?
