'I'm 17 and I'm paying for my Bone Marrow Transplant'
Meet 17 year old Andrew Davies from Chesterfield.
When he was 13 he was diagnosed with an extremely rare form of cancer.
During treatment Andrew asked a nurse how much it was costing the NHS. Her answer? £150k. He promised he'd raise that amount and give it back.
He's half way to his target.
Here he is talking to BBC Radio Sheffield's Toby Foster.
