I read a bit about MDS back when I started treatments... since I knew it was a possible side effect of the chemo. The University of Arkansas has done many studies on MDS. Personally, I'd get a second opinion. Statistically speaking, MDS as a side effect of chemo is rare. It does happen, but it's rare. From the cheap seats where I sit, I must say, I'm puzzeled at the doctors' "guesses" at this point. Are you seeing general oncos? If so, they're really not equipped to address transplant patients in general. They don't administer transplants and they don't have much of an idea on how the chemo impacts the bone marrow and the different stages of development the bone marrow undertakes. I'd get a second opinion perferrably from someone who treats stem cell transplant patients...like a MM specialist at a BMT clinic.
Here's a suggestion that can't hurt, go to the Huntsman Chat board and explain your situation and ask the question. The MM specialist from the Huntsman provide the best answer they can without breaking the law. And by the way, the specialist is named in almost all of the Arkansas studies on MDS...he's a PhD and knows MDS very well.

I hope it turns out neither of their guesses are true
Best of luck
