Tests and next steps for a malignant brain tumour (brain cancer)

Main tests for a malignant brain tumour (brain cancer)

If the GP or specialist thinks you might have a brain tumour, they'll probably refer you for further tests at the hospital.

This is usually a scan of your brain to see if you have a tumour, such as:

Getting your results

You may get some results on the day that you have tests, or after a few days.

You can call the hospital or your GP if you're worried and they may be able to update you if your results are ready.

If you're told you have a brain tumour

Being told you have a malignant brain tumour can feel overwhelming. You may be feeling anxious about what will happen.

You'll be helped through your diagnosis and treatment by a team of specialists.

This team will include a clinical nurse specialist who will be your main point of contact during and after your treatment. You can ask them any questions you may have.

Next steps

If you've been told you have a malignant brain tumour, you'll usually need more tests.

This will help your specialist team decide what treatment you need.

You may need:

  • more scans of your brain
  • blood tests
  • a lumbar puncture to test the fluid around your brain and spinal cord
  • a small sample of cells to be taken from the brain tumour (a biopsy)

You may not have all these tests.

The results of these tests can show how far the cancer has spread, and if the cancer has been caused by certain changes in your genes.
