Michelle,
Transplants, whether from a related or unrelated donor, have three phases: the preparatory regimen, the transplant hospital stay, and the recovery period. You can find good descriptions at the websites of the
National Bone Marrow Transplant Link,
BMT InfoNet, and
National Marrow Donor Program.
Here at Marrowforums you'll find a number of descriptions of individual transplants experiences in forum threads in this "Transplants" section, and you are welcome to read
my wife's transplant story in the Member Profiles section.
You can read more transplant stories in the blogs of some forum members. For example, follow the blog link from forum member
mausmish's signature.
