Jonjo Rooney was diagnosed with leukaemia in 2006, aged 23. "To be told you have leukaemia at the age of 23, it was like a nightmare. But I didn't have time to think because it was on to the treatment straight away." Jonjo had chemotherapy and then a bone-marrow transplant in July 2007. Despite the complications after the operation, Jonjo got through it and he is now in complete remission. Ever since his diagnosis he has supported other patients - going into hospitals and talking to patients across the world online - as well as raising awareness by talking to patient support groups and schools up and down the country. For the last 4 years he has also fundraised for Leukaemia & Lymphoma Research taking part in bikeathons and running the Great North Run and London Marathon for the blood cancer charity.
