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