Hopes for new child cancer test
Scientists are beginning work to genetically test tumours from children with cancer.
They hope this will give younger patients access to newer, more personalised medicines and further improve survival rates.
Fourteen-year-old Jack Daly was left with damaging after-effects following radiotherapy for a brain tumour when he was seven.
Jack and his mother Helen told BBC News about the lasting effect of the radiotherapy and how they hope the new test will make a huge difference to the quality of life for children in the future.
