In February 2002 doctors at Alder Hey Hospital, Liverpool, diagnosed Shannon as having a life threatening condition Aplastic Anaemia. She had just turned 7, before that she had been a happy, healthy little girl.
After being told a bone marrow transplant was her only hope of a cure, but with no suitable donor on the register, her aunt Jackie organised Blood Donor clinics throughout the North West. This resulted in almost 7000 people registering with the Anthony Nolan Trust, an organisation specialising in matching patients with suitable bone marrow donors. Unfortunately, by the time a perfect match was found Shannon was too ill to have the life-saving operation and sadly, on the 17 July 2002, just 5 short months after first diagnosis, Shannon lost her very brave battle.
