God's peace John. I am a survivor, but mine was caught asymptomatic and early, but the gene is in my family blood too (lost parents and grandparents).
There are no words for this. As a Believer, I placed my life in my Creator's hands. Lying on the gurney awaiting surgery, a Messenger came behind me and placed her hand on my arm. In my departed mother's voice I heard, "It's not good, but it will be good."
It sounds as though you are loved and that you love. That is the key to our lives, I believe. You have been added to my daily intercessions, you and your family, for courage, peace, strength, care and love. His grace is sufficient for the rest.
God's great peace to you.
