How many registered bone marrow or peripheral blood stem cell donors are there?
At the time of this writing, the National Marrow Donor Program (NMDP) boasts a registry of over 5.5 million donors. While you may feel that certainly sounds like a lot, the chances of finding a match have been reported as much as 1:20,000 and as little as 1:100,000; the ratio is even higher for minority groups. This ratio significantly lowers the chances of funding a life saving match. All the more reason to become a donor.
