She began treatment on her fifth birthday in October and underwent eight months of intensive chemotherapy.
She has also taken part in a clinical trial at Addenbrooke’s Hospital, in Cambridge, which is investigating ways to improve survival rates and reduce long-term side effects for young people with ALL.
Sam said: “We felt if we were able to help children in the future by doing these trials, it was very important, because if other children in the past hadn’t taken part in trials, then Nina wouldn’t be on such a good treatment plan.”
Her family saw “a turning point” when Nina began a newer treatment designed to help the immune system target leukaemia cells.
“By Christmas Day she was dancing in the front room – that treatment really changed things,” said Sam.
“She’s a really confident little girl and she’s just got on with it. She’s made friends at school and in hospital and will happily talk to people about her leukaemia.
“Now we just want Nina to complete her treatment with as few complications as possible and go on to live her life like any other child.”
Nina is now in the maintenance phase of her treatment, which is due to continue until December 2027, and is fronting a campaign led by Cancer Research UK to share her story.
