Surgery is one of the main treatments for brain and spinal cord tumours. You might have an operation to: Show
Having brain surgery might sound like a frightening procedure, but it is quite safe. Doctors who carry out these surgeries are very skilled specialists. You can share your concerns and worries with your doctors and cancer nurse specialist. They will be able to tell you what will happen during the operation. Brain surgery is not suitable for everyone. It’s a major operation so you need to be well overall. And some tumours grow in areas of the brain that are difficult for doctors to operate such as the brain stem. Speak to your doctor about what other treatments you may be able to have if you can’t have brain surgery.
Who does your surgery?A specialist team of doctors does your surgery. They are called neurosurgeons. You might have a team of neurosurgeons working on your operation. They are led by the consultant neurosurgeon. You might have other specialists working with the team. For example, you might have an Ear, Nose and Throat (ENT) surgeon if you have a vestibular schwannoma (acoustic neuroma) or a pituitary tumour.
Surgery to remove all or part of the tumourSurgery is an important part of your treatment. Even if your surgeon doesn’t think they can completely remove the tumour, they are still likely to try to remove as much as possible. This can help to slow down the progression of the tumour and relieve your symptoms. There are 2 main types of brain tumour surgery. They are called craniotomy and neuroendoscopy.
CraniotomyA craniotomy is the most common type of operation for a brain tumour. You usually have a craniotomy under a general anaesthetic. This means that you will be asleep and won’t feel anything. During a craniotomy, the neurosurgeon cuts out an area of bone from your skull. This gives an opening so that they can operate on the brain. You have scans before the operation to help your surgeon know where the tumour is. You may also have scans during the operation. Some of these scans are loaded into a computer to give the precise position of the tumour. Your surgeon uses different tools to remove the tumour. They can use:
After removing the tumour, your surgeon puts the bone back (this is called a flap). They secure the bone with small metal brackets and stitch the skin over it. In most cases, the hair will hide the scar. Awake craniotomyYour surgeon might suggest that you have an awake craniotomy. You may have it if your tumour is close to a part of the brain that controls important functions such as the speech, movement or feeling. There are different ways of having an awake craniotomy. Some people are awake (conscious) for part of the operation. Other people are awake the whole time. Ask your surgeon what will happen in your situation. If you are going to be awake for part of the operation, you have a general anaesthetic at the start of it. The anaesthetic is then reduced so that you wake up for the main part. You then have another general anaesthetic for the last part of your operation. During an awake craniotomy, the surgeon asks you to do tasks while they check the function of different parts of the brain. For example, they might ask you:
Once the tumour is removed, the surgeon repairs the skull and stitches up the skin. The idea of having brain surgery when you are awake might sound very frightening. But this is a common operation and you will not feel any pain. You have an anaesthetic during the operation to numb any areas that feel pain such as the skin and muscle. The brain itself does not have pain receptors so it doesn’t feel pain. Your surgical team will make sure that you are as comfortable as possible. You have a nurse with you all the time, to help you feel calm and safe. Some neurosurgeons do the operation while monitoring the brain electrical activity. This is called neurophysiological monitoring. It can make surgery safer and allow more tumour to be removed. NeuroendoscopyNeuroendoscopy is also called keyhole brain surgery. You might have it to remove all or part of a tumour in the fluid filled spaces of the brain (ventricles). You may also have a neuroendoscopy to remove a build up of fluid in your brain (hydrocephalus). An endoscope is a medical instrument, made up of a long tube with a camera attached to a monitor and an eyepiece. Endoscopes can be flexible (bendy) or rigid (fixed straight). You surgeon carefully makes a small hole into the skull. This is called a Burr hole. They then put the endoscope through the hole. The surgeon can see what is at the tip of the endoscope either through the eyepiece or on a monitor. There are tiny forceps and scissors at the end of the endoscope. They use these to remove the tumour.
Removing a pituitary tumour via the noseThe pituitary is a small gland that lies in a hollow space above the back of your nose. It may be possible for your surgeon to remove a pituitary gland tumour via the nose. This is called transsphenoidal surgery. Your surgeon usually makes a small cut on the thin wall of bone and cartilage that separates the nostrils (the nasal septum). They put tools through this hole and up to the pituitary gland to remove the tumour. Your surgeon may also use an endoscope. An endoscope is a long tube that has a camera and an eyepiece. They use the endoscope to operate surgical instruments and remove the tumour. Transsphenoidal surgery isn’t suitable for everyone. You may need to have a craniotomy if you have a large pituitary gland tumour. You may have side effects after transsphenoidal surgery, but this is rare. Side effects include:
Talk to your surgeon about the possible side effects of transsphenoidal surgery and craniotomy if you are worried.
Surgery to give chemotherapyDuring brain surgery, you might have chemotherapy into the area of the tumour as a wafer (implant). Or you might have a ventricular access device (an Ommaya reservoir) put in. Ventricular access devices allow you to have chemotherapy straight into the fluid filled spaces of the brain (ventricles). We have information about chemotherapy wafers and ventricular access devices in the chemotherapy section.
Surgery to drain a build up of fluid on your brainA build up of fluid in the brain is called hydrocephalus. You might have the build up of fluid drained during surgery to remove the tumour, or as a separate operation.
Side effects of brain surgeryIt can take some time to recover from brain surgery. You might have some side effects immediately after surgery such as weakness and dizziness. And some long term side effects such as problems with your speech. It can be upsetting to learn about these side effects. Talk to your doctor or clinical nurse specialist about what to expect after brain surgery. Ask them about the side effects you might have and the support that will be available to you. For support and information, you can call the Cancer Research UK information nurses on freephone 0808 800 4040, from 9am to 5pm, Monday to Friday. They can give advice about who can help you and what kind of support is available.
