A family is campaigning to encourage more people to sign up, to the bone marrow and stem cell register. Jaskomal Sher-Gill from Bedfordshire was given new hope of fighting her blood cancer, after discovering her brother was a match for stem cell donation.
But, despite a successful transplant, Jaskomal died at the age of 23, her immune system too low to fight off a chest infection. Well, her family have launched a foundation in her memory, to give others with lymphoma a better chance of survival.
And - as Olivia Paterson reports - there's a particular need to find donors from ethnic minority backgrounds.
