Symptoms of brain and other CNS tumours can depend on where the tumour is, how fast it is growing and 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.
Symptoms are not the same in every child, but can include:
- nausea or vomiting
- problems with vision, hearing or speech
- 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
- failure to thrive – where a child fails to gain weight appropriately
- decrease in physical or intellectual abilities, or losing abilities that they had before
- increase in head size or swelling of the soft spots of the skull.
Note about symptoms
Many conditions – including common childhood infections – can cause these symptoms, not just brain and other CNS tumours. If your child has any of these symptoms and you are concerned, talk to your child’s doctor.
