A brave teenager who was left unable to open her eye after suffering from a massive brain tumour lived for six years without knowing about her disease.
Allana Prosser was just 11 years old when she first started having daily headaches in 2009.
But it wasn't until earlier this year that it was finally discovered that she had a tumour called a Craniopharynigioma.
The growth was pushing on Allana's optic nerves and for some time the 17-year-oldfrom Bedworth near Coventry was unable to even open her right eye
