Thank you for your research! Can you say more about what you did? I'm a DLBCL survivor. Funny thing, I always hear it is the most common but I could never find anyone that had it when I was sick (and I looked) ... fortunately I found Imerman's Angels to help the next person after me, but that's another story.
I wish you only the best ... on the Spark journey, and more importantly, on the journey of your life! Make the most of everyday ... it's a wonderful gift!
