My 10 year old daughter, Lauren, was diagnosed with CML this past September. I was told that she would need a BMT, I have no other children therefore she will need an URD. I was told of two methods to prepare the body prior to transplant, full body radiation or a new method, photoferesis. Has anyone heard of this method or anyone that has went through it? I just don't know what to do. They both sound scarey. Help.
