Bob,
I wish you all the best as you " travel this road". Seven years ago, when I was 57, I was told that I had an aggressive prostate cancer. My personality being what it is wanted to "do something right away". The Dr said, "You are going to become a student of this disease so that we can do what is right for you". He was right, and I did, but the process was all consuming for awhile. I learned to embrace the disease as part of me. Seven years later I believe that I am cancer free, but not without a few lifestyle modifications.
Bottom line though is that it sure has altered my view of things, in a good way. One of the richest, most meaningful experiences of my life which I wouldn't trade in spite of the outcome.
I truly wish you all the best.
Respectfully
pake
