The parents of a three-year-old battling cancer say they mistook their daughter's symptoms for a virus.
Ava Bolton, from East Ayrshire, Scotland, developed bruising around her eyes and began walking with a limp towards the end of last year. She then became sick, lethargic and pale.
Her mum and dad, Scott and Natalie, both 34, initially assumed it was a virus, but when the youngster refused to walk they became more concerned and took her to see a GP.
