You have every right to be concerned about the scan.  Let's hope for the very best.  I am amazed at the love and caring on OCF as demonstrated by suemarie and her mother taking care of your dogs.  At least that is one less thing to worry about.
I am finishing up reading "Why Bad Things Happen to Good People".  While I liked the beginning and its exegesis of the Book of Job, not sure about its conclusions.  All I do know is that very bad things do happen to very good people who do not deserve such suffering.  I can only hope I can muster a fraction of your fortitude and spirit if I face round 3.  You consistently demonstrate personal courage, faith, and a continued zest for life despite facing more than most people could bear.  You are in my thoughts and prayers
