Symptoms are not the same in every child, but can include:

  • headaches
  • nausea or vomiting
  • problems with seeing (reduced and or double vision), hearing or talking
  • problems with balance or coordination
  • weakness or numbness in a part of the body, especially only on one side
  • back pain
  • changes in behaviour
  • weight loss or weight gain for no reason
  • seizures (fits)
  • drowsiness or coma.

Very young children or babies may not be able to tell you their symptoms. Symptoms in young children can also include:

  • irritability
  • loss of appetite
  • delays in development
  • not thriving – where a child fails to gain enough weight
  • decrease in physical or intellectual abilities, or losing abilities that they had before
  • increase in head size or swelling of the soft spots (called fontanelle) of the skull.

Symptoms of brain and other CNS tumours can depend on:

  • where the tumour is
  • how fast it is growing
  • the child’s age.

Some symptoms occur because the tumour creates pressure in the brain. Pressure in different parts of the brain can produce different symptoms.
