"I detected my son's rare cancer using flash on my mobile phone"

A mum detected her son's rare cancer using the flash on her mobile phone camera. Sarah Hedges, 40, was cooking shepherd's pie for dinner when she looked across at son Thomas, three-months-old, and saw a "white glow" in his eye. The mum-of-four said it was reflecting the light "like a cat's eye" and took photos with the flash turned on using her phone to see if she could spot it again. She Googled what she saw - and reports said he might have cancer - so she showed the photos to her GP.
