A mother who thought her teenager's tiredness, headaches and sickness were results of stress caused by his GCSE exams was stunned when he was told he had a brain tumour.
Samantha Halket originally believed 16-year-old Thomas' clumsiness was a "gangly teen growth spurt" and considered stress had been caused by tests at school.
Thomas' headaches got worse though and, Samantha, 39, booked her son an eye test at Specsavers. Opticians referred him to the emergency eye clinic at Royal Stoke University Hospital.
