Overview

• Rosie Hassall, age five, was diagnosed with a paediatric bithalamic glioma, an ultra-rare and aggressive brain tumour representing less than 1% of cases.
• Her symptoms began in November 2024 with severe headaches and unusual eye movements, initially misdiagnosed as migraines before an MRI revealed a six-centimetre tumour.
• Doctors confirmed the tumour was inoperable and highly aggressive, with an average prognosis of 9–12 months, though her family remains hopeful she can defy the odds.
• Rosie has undergone radiotherapy and is now receiving chemotherapy, with quarterly scans to monitor tumour growth and progression.
• The family has raised over £33,000 through GoFundMe to support Rosie's care and is sharing her story to raise awareness and promote research into rare paediatric cancers.
