Non-cancerous brain tumours

Also called Benign brain tumours, Meningioma, or Pituitary adenoma

A non-cancerous (benign) brain tumour is a growth in the brain that grows slowly and does not spread to other parts of the body. Common types include meningiomas, pituitary tumours and acoustic neuromas. Even though they are not cancer, they can cause problems by pressing on the brain, depending on their size and position.

What it is

Small tumours that cause no symptoms are often monitored with regular scans.

Treatment may include surgery, radiotherapy or radiosurgery, and medicines for pituitary tumours. Most people do well after treatment.

Common signs

  • Headaches that are new or getting worse
  • Seizures
  • Vision or hearing problems
  • Changes in memory or personality
  • Weakness or numbness on one side

How it is usually diagnosed

  • MRI or CT scan
  • Hormone blood tests for pituitary tumours
  • Vision and hearing tests

Records worth keeping

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

  • MRI reports over time
  • Neurosurgery letters
  • Hormone test results
  • Vision field results

Questions to ask your doctor

  • Does the tumour need treatment or monitoring?
  • How often will I need scans?
  • Can I drive?

When to get help right away

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

  • A seizure, sudden severe headache, sudden vision loss or new weakness: call 112
