Case History

From everything I was reading, the only hope for a cure was a bone-marrow transplant from a matched donor, ideally a sibling.
I have two brothers, and we quickly arranged tests to determine whether either could provide the lifesaving marrow I needed.

We had always been close, but it turns out my brothers and I were even closer than we thought.
By an immense stroke of luck -- and luck should never be played down in medicine -- both brothers were identical matches to me.
