Surgery for brain and spinal cord tumours
A biopsy means taking a small tissue sample from your brain and looking at it under a microscope. This helps your doctors decide the best treatment for you.
You usually have a biopsy of your brain under general anaesthetic. This means that you will be asleep and won’t feel anything.
A biopsy is done by a specialist doctor, called neurosurgeon. You usually have it as part of the operation to remove the brain tumour, but you may also have it on its own.
There are different types of biopsies. The difference between them is the way the surgeon does the biopsy. You might have:
a biopsy as part of the operation to remove the tumour
a needle biopsy
an open biopsy
a neuroendoscopy
You might feel a bit drowsy from the anaesthetic when you wake up. You should be able to eat and drink once you are fully awake.
You go from the recovery area to the ward. Your nurse will keep a close eye on you for the first few hours. Your team asks you questions and gives you instructions to follow to check that you are fully awake. They will shine a light in your eyes to check your pupil reaction.
You have medicines to help with any pain you might have. It's not usually too uncomfortable.
You normally stay overnight in hospital after your biopsy. But some hospitals do biopsies as a day case procedure.
Your doctor will let you know when they think you can go home. Everyone takes a different amount of time to recover from a biopsy.
Take any medicines you have been prescribed, exactly as your doctor or pharmacist told you. Your pharmacist can make you a reminder sheet if it would help you. Take your painkillers regularly if they have been prescribed. Speak to your GP or hospital doctor if you find that they aren’t working. They can do a lot to help, like changing the amount or the type of pain killers.
Your neurosurgeon will let you know when it's safe to drive.
A biopsy is a very safe procedure but your nurse will tell you who to contact if you have any problems afterwards. Your doctors will make sure the benefits of having a biopsy outweigh these possible risks.
The possible risks of having a biopsy are:
You may have some bleeding in your brain during or after the biopsy. This is usually a small amount. Your team will check for any signs of bleeding in your brain.
You may have antibiotics if you have signs of infection such as a high temperature (fever).
You might have bruising around the area where they put the cannula in and where they take the biopsy.
You may have drugs called steroids before and after the biopsy to help with swelling in your brain.

You have tests to diagnose a brain or spinal cord tumour. Some of the tests help your doctor find out how big the tumour is and whether it has spread.
Common symptoms of brain tumours include headaches, feeling or being sick and seizures (fits).
You might have surgery to remove all or part of your tumour. Or or to drain a build up of fluid (hydrocephalus) on your brain.
