Child cancer charity, CLIC Sargent, is concerned for the families it helps in East Anglia as it faces a 67% drop in funding across the region.
The charity has been key in supporting many families going through challenging times, particularly during the pandemic.
Lianne Roban from Bedfordshire is one of those who have benefited from the support.
She was so overwhelmed when she was told her son, Kian, had cancer that she contemplated taking her own life.
Kian was in intensive care when his airways were blocked by a tumour in his face.
A year on and Kian has stopped treatment and is now in partial remission.
Both he and Lianne are in a much better place and they say that is in part thanks to the support they received from CLIC Sargent.
It currently helps 150 children in East Anglia like Kian but a huge drop in funding across the east means that support could become less available in the future.
Young people have also struggled to adapt to difference in treatment during coronavirus.
For some when they reach a certain age, they are no longer allowed a parent to join them and support them through chemotherapy.
George Hatfield a 20-year-old theatre student treated at Addenbrooke's Hospital in Cambridge has struggled without someone to help him.
It has also meant the ringing of an 'end of treatment bell' has stopped.
What is an end of treatment bell?
Lots of young people ring them at the end of their cancer treatment. Usually in the hospital, many places stopped allowing the bells to be rung during the pandemic.
It is a big moment for many patients, signifying an important milestone.
