@garyr443 Cancer is where cells grow out of control - as such MPN's are cancer as cells/cell products are out of control. We are fortunate in some ways as we do not look like we have a disease and typically will not die from this as long as appropriate treatment protocols are followed. After three stints in the hospital as I was starting a trial, I really feel fortunate; I was on the blood disease floor (BMT, leukemia, lymphoma). I was able to freely walk the floor and getting glimpses in the room of others really made me thankful, as our journey, while not great, could always be much worse.
