I fell your pain. I too am at this site seeking information, help, guidance, advice, or whatever I can find about diffuse b cell non hodgkins lymphoma. My Dad, who is 69, was diagnosed with it on 4/10 and recieved his first CHOP-R21 treatment on 4/18. He is very sick and doesn't do anything but sit around in pain now. He is my idol and I want him better. If you find out anything, please let me know, and I will do the same for you. May God be with you.
