But I have a big decision to make. Should I get a Bone Marrow Transplant (BMT). Gerry had one in 2007, and they’re NOT FUN. It would mean going back into the hospital for at least 30 days, and right now the best doner that we’ve found so far is Max! There are millions of doners in the registry, though, so they’re searching to see if there might be a better match.
