My dad has recently been diagnosed with MPN with a treatment plan of venesection and hydroxicarbamide. Unfortunately the doctor hasn’t explained it very well and has said it’s not cancer. But all the research I’m doing is telling me that it is a cancer.. I just want to know what’s actually happening but to be honest there’s not been much information given. I was on holiday when my dad was diagnosed and i can imagine he was overwhelmed and didn’t ask many questions. Does he have cancer?
