I believe it is time for my father to make a switch to a different doctor and I am looking for advice. MD Anderson or Mayo? How do I go about finding a doctor who treats this desease and is truly an expert? Right now dad is back in the hospital for extreme lack of energy. Mom says he has been in bed all weekend. He is 70 and diagnosed only a month ago. So far no treatment other than transfusions which are not working. Help!
