An eight-year-old girl from East Yorkshire is undergoing treatment for ovarian cancer.
It is thought Sophie Fry is one of the youngest girls in the country to be fighting the disease, which normally affects much older women.
Sophie was diagnosed with cancer after she was taken to Scarborough Hospital earlier this year with abdominal pains. An ultrasound later revealed she had a tumour.
The youngster has since undergone an operation at St James's Hospital in Leeds, West Yorkshire, where she is now undergoing further treatment.
Relatives and supporters have now launched a fundraising campaign for the hospital unit caring for her and to help pay for a holiday.
Professor Hani Gabra, Director of the Ovarian Cancer Action Research Centre, said: "Cancers found in the ovaries of young children, called ovarian germ cell tumours, are a quite distinct disease from adult ovarian cancer, which most commonly affects women aged 50 and over.
"Germ cell tumours in children are thankfully rare and treatment is usually effective, with more than four out of five children who develop the disease surviving."
He added that little is known about the causes of ovarian cancer so it is vital there is funding to research the disease.
