What to look out for if you suspect your child has a brain tumour We want to raise awareness of the signs and symptoms of brain tumour in children, so that we can make interventions earlier. OSCAR’s Paediatric Brain Tumour Charity exists to support and care for children with brain tumours and their families, fund research and raise awareness of signs and symptoms. We always want the best for our children’s health and well-being, so it is important to stay informed about potential health concerns. Studies show that 72% of adults in the UK don’t know the signs and symptoms of brain tumours.
