'I'm donating my stem cells to save my son's life'

Available for over a year

Warren's son is in desperate need of a transplant to treat his leukaemia. 16-year-old Leo Sproson from Bromsgrove had a donor found before Christmas but that operation has now been delayed. His cause is so urgent that doctors have now asked Leo's dad to step in, even though he's not a perfect match. Image credit: DKMS
