The family of a six-year-old Fraserburgh girl who is battling a rare form of cancer say they're overwhelmed by the generosity of the public.

Olivia Downie's parents launched an appeal to fund her vital treatment, which cost tens of thousands of pounds.

Their daughter has spent more than a third of her life in hospital after being diagnosed with aggressive childhood cancer Neuroblastoma two years ago.

She was given groundbreaking treatment in Germany in 2010, but then doctors discovered two new tumours

Olivia is now undergoing new treatment in Aberdeen called RIST therapy which is shrinking the tumours.

Doctors hope to remove them and then give her a stem cell transplant to rebuild her immune system

The family are hopeful, but admit the past few years have been an ordeal.

Olivia's father Stephen said: “It’s just been a nightmare, an absolute nightmare."

Mother Lauren added: "When she’s in pain it’s so unbearable, you would do anything to swap places.”

The couple have been fundraising to help pay for Olivia's treatment, and have had phone calls from all over Britain from people wanting to help.

Lauren said: “We can’t express how grateful we are – it’s overwhelming

“I’d do anything in the world to make her better, but we have fear every single day.”

Donations can be made to Olivia's fund on the Families against Neuroblastoma website.
