A woman went to the optician thinking she just needed glasses, only for a brain tumour to be spotted that could have killed her in 24 hours.
Ellie Musgrove, 21, attended a routine appointment at Specsavers and 12 hours later she was getting ready for emergency surgery.
Medics say that if the tumour had not been spotted when it was then she could have died within a day, DailyStar reports.
