I dont have advice, but a sympathetic ear. my mother has been fighting a primary interperiatenial cancer for five years (closest related cancer ovarian) and last February she received a secondary diagnosis if AML. They doctors ahve fought htis with Vidaza since then, but her blood just does not make platelets, nuetrofils, or or other blood components without transfusions. She is at this point having platelets and 2 units of whole blood every week. As if this were not enough she has developed a severe heart issue. It is so hard to watch our loveds ones go through suffering. I am just trying to let you know, I understand what you may be feeling, and give you support from afar. Take heart, originally they told us mom only had a month to live, that was last February as I said. There are new meds they come out with often, and we are praying for miracles for the individuals and families. I understand this has all been supportive care for mom, but I am grateful for every day I have with her, as I never expected this many more. Take care, and I will pray for your grandfather.
