Brain tumours
Brain tumour symptoms can be very similar to those of childhood illnesses. And they vary between children.
It’s important for them to see their general practitioner (GP) if they have any of the following symptoms:
headaches
feeling or being sick
seizures (fits)
problems with their eyes or vision
problems with their strength, balance or coordination
changes in their behaviour
problems with their posture
delayed or stopped puberty
your baby's head measures larger than it should
The symptoms a child may have depends on where the tumour is in the brain. Symptoms can also be different depending on the child’s age and development.
Remember that cancer in children is rare and these symptoms can be caused by many conditions. But it’s important for your child to see their GP.
Read more below about the possible symptoms of brain tumours in infants, children and teenagers.
Your child might be feeling sick (nausea) or being sick (vomiting) regularly on most days. Early morning vomiting is common.
Your child might have a headache that doesn’t go away or keeps coming back. Headaches can also often happen with other symptoms such as vomiting.
Your child might have seizures. This is a seizure that is not related to a high temperature in babies.
Your child might have:
abnormal eye movements
a squint, when both eyes don’t look in the same direction
blurred or double vision
Head circumference is the measurement around your baby’s head. All babies have their heads measured when they are born and at their routine check at 6 weeks. They might have jumped a centile compared to their length and weight.
Make sure you take your red book to any appointments. Your baby’s health professional can record the measurements so that they can compare them.
This is usually a loss of skills they have already learnt including balance and sitting up. They might be having problems with their coordination or strength.
Walking might become more difficult, or look different, than before.
You might notice a change in their behaviour. In babies and young children, they might be sleeping a lot and have less energy than usual.
Older children and teenagers might also be very tired or have extreme mood changes. They might be confused.
Your teenager might have delayed puberty. The start of puberty for girls is usually the development of their breasts. For boys it is when the testicles get bigger.
Delayed puberty, for girls, means no sign of puberty by the age of 13 or no periods by the age of 16. For boys, it means no sign of puberty by 14.
Your teenager might start puberty, then stop. Doctors call this arrested puberty. Girls might start their periods, but they stop again.
HeadSmart aims to raise awareness of the common signs and symptoms of brain tumours in children and teenagers. They provide information for:
parents
the public
health professionals
They have more in depth information about the symptoms of brain tumours.
There are guidelines to help GPs know when to refer a child to see a specialist. These guidelines are very clear that that the GP should take the parent or carer's concern about their child into account when deciding about a specialist referral.
Your GP should consider referring your child to a specialist within 48 hours if they think there is a problem with the way the brain or central nervous system is working. This may include new problems with:
movements
head tilt - your child might be holding their head in an abnormal way
strength
balance
coordination
confusion
tiredness
persistent vomiting with or without headaches

Tumours affecting the brain and central nervous system are the second most common type of children’s cancer in the UK. Around 420 children are diagnosed with these tumours each year in the UK.
Tests for a children’s brain tumour might include a neurological examination, MRI scan, CT scan, blood test, lumbar puncture or biopsy.
The main treatments for children’s brain and spinal cord tumours are surgery, radiotherapy and chemotherapy.
We don't know what causes or how to prevent most childhood cancers. There are some factors that can increase the risk of cancer in children.
