How will I know if my child has a brain tumour?

Symptoms of a brain tumour vary from child to child and can also depend on where they are located in the brain. Some of the brain tumour symptoms are similar to those of other common childhood illnesses. The presence of a symptom does not necessarily mean that your child has a brain tumour.

Childhood brain tumour symptoms

Common symptoms of childhood brain tumours include:

  • persistent vomiting/feelings of nausea (over a two week period)
  • recurring headache (over a four week period, particularly on waking)
  • abnormal eye movements
  • fits or seizures
  • behaviour change
  • abnormal balance/walking/co-ordination
  • blurred/double vision
  • abnormal head position (such as a head tilt)
  • delayed or arrested puberty (puberty that doesn’t start, or starts but doesn’t progress as expected)

If your child has one or more of the above, you should take them to see a GP, explaining your worries. If they have two or more, ask for an urgent referral which means that your child will be given an appointment with a specialist who can further investigate the causes of the symptoms.

If you child’s symptoms are limited to eye problems and/or headaches, your GP will often recommend an eye test. You can speed up the process, by taking your child to an opticians whilst waiting for the appointment to see the GP.

More information about the symptoms of a brain tumour in children can be seen on the Symptoms of brain tumours in children page.

Childhood brain tumour diagnosis

If your GP or A& E doctor suspects a brain tumour, they will refer your child to a specialist, such as a neurologist or paediatrician. They will ask questions about your child’s health and carry out a physical examination, as well as a number of other tests – such as a neurological test. This looks at their sight, hearing, alertness, muscle strength, co-ordination and reflexes. Your child will also need an MRI (Magnetic Resonance Imaging) or CT (Computerised Tomography) scan to confirm whether a brain tumour is present.

Following a scan, if a childhood brain tumour is found, your child may be referred to a neurosurgeon. A biopsy may be taken from your child’s tumour. This involves an operation to take a sample of tumour cells. Alternatively, if possible, as much of the tumour as possible will be surgically removed. In both of these cases, cells from the tumour will be analysed in a laboratory, so that a detailed diagnosis of the exact tumour type and grade can be given. This is used to plan the best course of treatment for your child.

Opticians can also help diagnose childhood brain tumours. If a tumour is causing increased pressure in the skull, this can sometimes be seen at the back of the eye during an eye test. If an optician sees this, they will refer your child to a specialist eye doctor called an ophthalmologist. They may refer onto the other specialists, or directly for a scan.

Common childhood brain tumour types

There are many different types of childhood brain tumour. The most common types in children are:

Around half of all childhood brain tumours are a type of ‘glioma’. This means they are derived from the various glial cells. Astrocytes, oligodendrocytes, and ependymal cells are all types of glial cells.

Of all gliomas, the largest subgroup is astrocytoma (arising from astrocytes) and these make up over two-fifths (43%) of all brain and spinal tumours in children.


In children, most astrocytomas tend to be slow growing (73% are low grade) and are diagnosed throughout childhood with no strong pattern by either sex or age. Pilocytic astrocytoma tumours are more common in children.

Approximately 10-15% of childhood brain tumours in the UK are a type of high-grade astrocytoma called a Diffuse Intrinsic Pontine Glioma (DIPG). DIPG is a fast growing, type of brain tumour that originates in the brain stem. They often appear in children aged around six years old. Recently it has been renamed as a ‘diffuse midline glioma’, but you may still hear it being called by its old name.


Ependymomas account for about 10% of childhood brain tumours – they are the third most common type of brain tumour in children.

About 20-25% of childhood brain tumours are embryonal tumours. These were previously called primitive neuroectodermal tumours (PNETs). They are usually high grade tumours and occur most frequently in younger children – with more than half of all embryonal tumours being diagnosed in children under 10 years old.

These are the most common type of high-grade tumour in children. They make up around 20% of all childhood brain tumours. They are more common in boys than girls and are most commonly diagnosed at around the age of 5 years old.

Read more about medulloblastomas.

These account for 8% of childhood brain tumours. They are low grade and do not usually spread. They are near important structures in the brain and can cause problems as they grow and can cause changes in hormone levels and problems with eyesight. Children with craniopharyngioma can experience weight gain and growth problems.

What causes childhood brain tumours and why?

Very often, the answer is that we just do not know. This can be one of the most difficult things to accept as a parent, as it can leave you feeling helpless. Brain tumours are nobody’s fault. There is no research to show that anything you may have done during pregnancy, or in your child’s early infancy, could have caused their brain tumour.

Learn more about how brain tumours form on our What is a brain tumour? page.

How are childhood brain tumours treated?

Treatments for childhood brain tumours may include surgery, radiotherapy, chemotherapy or proton beam therapy. Several factors influence which treatment will best help your child. A team of specialised professionals, called the MDT (Multi-Disciplinary Team) will consider your child’s individual diagnosis and take account of factors, such as the size and location of the tumour, the type of tumour your child has and how quickly it is growing. They will also consider your child’s age and their general health.

What’s the long-term impact of a childhood brain tumour?

Long-term effects from a childhood brain tumour vary from child to child and depend on the exact location of the tumour within their brain, the therapy given and the age at which it is given. Your child’s consultant will be able to talk you through possible long-term effects they might experience. Some children with a brain tumour grow up to have little or no long-term effects, while others may experience some of the following:

  • Learning difficulties – These can occur as a result of the tumour itself, the impact of treatment, or the fact that they have had to take time out of school and therefore miss lessons. Read more about learning difficulties.
  • Sight problems – A brain tumour can cause partial or full loss of sight. This can be a result of the location of the tumour within the brain or the long-term effects of radiation therapy.
  • Impacts on growth, puberty and fertility – Treatments, such as radiotherapy and chemotherapy, can delay puberty and affect growth and fertility. Your child’s doctor can address these impacts with some medicines and artificial hormone replacement.
  • Physical problems – Some children who have had a brain tumour will be left with a long-term physical effect, such as weakness in a limb (hemiplegia), or difficulties with balance. Physiotherapy is one possible treatment that may help children to adapt.
  • Emotional difficulties A brain tumour and treatment can cause changes to the brain which can lead to emotional changes and difficulties. Emotional difficulties can also be due to changes in your child’s social interactions – from feeling different from friends and not being able to participate in the same activities.

Coping as a family

Coping with a diagnosis of a childhood brain tumour can have a huge impact on you, as parents/carers, and on the rest of your family.

The Brain Tumour Charity’s Children and Families Service can give help to you or your child if you need it. We have dedicated Children and Families Workers who can offer both practical and emotional support to parents, children and siblings. We also have a dedicated Young Adults Team, who work with people from 16 – 30 years old.

If you have any questions, or would like to talk to a member of the Support team, please phone 0808 800 0004 or email support@thebraintumourcharity.org.
