Kerry, I can't answer the above, but I want to share with you that after my husband's recurrance, there were some questions I wanted answers to without John hearing the questions or the answers, so I wrote a certified letter to his surgeon, who has been his primary Oncologist throughout the past year and now knows us both well. I asked my questions, he wrote me back with very honest answers. This conversation is still just between the Doc and me. If there are things you want to know and don't want Stephen to have to deal with at this point-let his Doc know that you need some private communication. Wishing you both the best luck going forward. Amy
