Scotland's 'miracle child' is set to run the Edinburgh Marathon - almost 40 years on from his blood cancer diagnosis.
David Campbell, 41, became the first person in the world to undergo three bone marrow transplants in 1984 after he was diagnosed with Leukaemia aged two.
At first, the treatment was unsuccessful and David's parents were told to plan a funeral for the toddler who only had a 20 percent chance of survival.
