A good place to start with the type of transplant you’ll be having would be this discussion I started a few years ago. You can reverse the order of the conversations in the little bubble below the opening discussion paragraph. You’ll find newer posts by @katgob who very recently had her allogenic bone marrow transplant.

Another great discussion was started by @mary612 when her husband was being scheduled for a bone marrow transplant a couple of weeks ago.

We are open an honest with our replies so don’t let some of the experiences scare you off. Each of us goes through our own journey in this procedure. And each clinic/medical facility will have their own protocols. But the process is the same. I’m fond of saying it’s not a walk on the beach, but ultimately it is the 2nd chance at life for those of us who have no other option and well worth the effort. Again, let me know if there’s anything I can help you with.
