Stem cell donors: 'It's a small sacrifice in the bigger picture'
For many people diagnosed with blood cancer, a stem cell transplant will be the only way they can recover.
However, currently less than 6% of people in Northern Ireland are registers as donors according to DKMS, a blood cancer charity.
One man from Newry, Seán Brady, said the decision to sign up was an easy one - it was 12 years after he joined the register that he got a phone call telling him he was a potential match for a patient.
"It wasn't painful - it was uncomfortable, but in no way painful," he said.
"For me it was a very small sacrifice for the bigger picture in the grander scheme of things of actually what it could result in, in helping someone."
