Hannah York Drives Earlier Childhood Sarcoma Diagnosis Guidelines

What changed

CCLG: The Children & Young People’s Cancer Association has launched new guidelines to help healthcare professionals recognise soft-tissue sarcomas in children and young people. The Child Cancer Smart campaign is promoting them alongside Hannah York’s account of her daughter Liberty’s angiosarcoma, which began with symptoms in May 2024 and took her life at 19 on 1 June 2025.

Why it matters

Liberty’s swelling and pain were initially treated as mastitis, an abscess and possibly hormone-related changes. By the time surgeons operated, the tumour weighed 10lb (4.5kg), and the cancer spread to her lungs within six weeks.

That is the practical problem these guidelines are intended to address: rare cancers can look like ordinary illnesses, especially when symptoms appear in young people. Soft-tissue sarcomas account for about 7% of childhood cancers, according to CCLG, but their rarity can make recognition harder.

Hannah says she does not know whether an earlier diagnosis would have saved Liberty. She does know that earlier action might have given her daughter more of a chance. The guidelines cannot change what happened to Liberty, but their value will ultimately depend on whether they help clinicians recognise unusual swelling and skin changes sooner.
