Thanks for looking out Charm. I saw the article, and received another injection yesterday! I have been takng epogen/ procrit for a few years, even before cancer diagnosis. I knew this for a year now that it can increases tumor size. You have to sign a FDA required form you were advised of this fact. I spoke to my oncologist, and was told then that it is a concern when given above certain blood levels, like the article mentioned. if my Hemaglobin goes past 10, which is still low, I do not get an injection. Last week I was 8.7. Yesterday was 9.3. I go back next week, and may get one last shot after the cbc which I think may be around 9.9 Normal hemaglobin fora male is around 13-17. Women are slightky lower. it does improve the QOL, so the reason I still get mine. The alternatives is a blood trnfusion. I woud not be surprised if it increases, accelerates tumors even when given properly at lower blood levels. Who knows if his had an impact on my recurrences.
