Malignant brain tumour

Also called Brain cancer, Glioma, or Glioblastoma

A malignant brain tumour is a cancerous growth in the brain. It can start in the brain (primary) or spread there from cancer elsewhere in the body (secondary). Malignant tumours are more likely to grow quickly and spread into nearby brain tissue. Symptoms depend on the size and position of the tumour.

What it is

Treatment usually includes surgery to remove as much as possible, followed by radiotherapy and chemotherapy.

A specialist team plans treatment and supports people with symptoms, rehabilitation and driving rules.

Common signs

  • Headaches that are new or getting worse
  • Seizures
  • Feeling sick
  • Changes in personality or memory
  • Weakness on one side
  • Vision or speech problems

How it is usually diagnosed

  • Brain scans (MRI or CT)
  • Biopsy or surgery to examine the tumour
  • Molecular tests on the tumour

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • MRI reports over time
  • Histology and molecular reports
  • Neurosurgery and oncology letters
  • Seizure medicine records

Questions to ask your doctor

  • What type and grade of tumour is it?
  • What are the aims of treatment?
  • Can I still drive?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A seizure, sudden weakness, severe headache with vomiting or drowsiness: call 112
