Multiple Myeloma and other bone marrow/blood cancers are not well known nor are they some of the more “popular” cancers that receive a lot of attention and research. Currently, about 70 percent of patients searching for a marrow or blood stem cell transplant do not find a suitable match within their family. When patients do not have family matches they request these services of the BE THE MATCH Marrow Registry. Zac was extremely lucky that in his large family of seven brothers and sisters, he had three potential matches. For perspective, even with a registry of more than seven million, many patients still cannot ever find a single match.
