Awesome that you have a donor!
For those of you who wish you could do more to help out in situations like this, become a marrow donor. Most donations now occur through something more like a blood donation than an actual draw of marrow from the bone, although that is still required for some cases. All it takes is a cheek swab to get listed. Statistical likelihood of being a match are slim, but that's why it's important for lots of people to sign up.
