Almost 9,000 people joined the stem cell donor register last week after an appeal went out through the family of a sick child.
Daniel Greer was diagnosed with leukaemia three weeks ago, and the disease is now spreading rapidly and aggressively. The 14-year-old's only chance of beating the disease is through a bone marrow transplant.
Paul Greer told Belfast Live of the pride he and his wife have for their son, who is fighting the disease with true inspiration. Doctors have told the Newry family that his diagnosis is fatal unless they can find an appropriate bone marrow donor.
