Abnormal growth

Babies, children and teenagers will grow differently during childhood and puberty, but this is normally within a particular range. If their growth stops or is delayed, this can be a symptom of a brain tumour.

When might abnormal growth be a symptom of a brain tumour?

If you're worried that your child's growth has stopped or is lagging behind other children their age, you should make an appointment with your GP as soon as possible.

It's important to be aware that a baby, child or teenager who has abnormal growth caused by a brain tumour, they are is likely to have other symptoms as well, particularly:

  • delayed puberty
  • excessive fluid intake (feeling very thirsty and drinking a lot)
  • excessive urine (wee) production.

You should look out for these symptoms carefully.

How do I know if my baby, child or teenager has abnormal growth?

The World Health Organisation has growth charts to show the usual range of growth for healthy children.

If you're concerned about your child, you should make an appointment with a GP.

If you're a teenager and you're worried about your growth, it's best to talk to your GP about it.

If symptoms appear suddenly or are severe, take your child to A&E or phone 999.

I think I have a brain tumour, what should I do?

Brain tumours are rare, however, if you're worried and a symptom persists or if your child has more than one symptom of a brain tumour then:

  • Talk to your doctor
    GP appointments are usually quite short, so make sure you find out how to best prepare for your child's appointment.
  • Get an eye test
    If your child's symptoms are limited to changes in vision and/or headaches, get their eyes tested by an optician before seeing your GP.
  • Go to A&E
    If the symptoms are sudden or severe, you should go to your emergency department or call 999.
