Pete, you have been in my thoughts and prayers a lot since I heard.
I've been a "memento mori" thinker and we all have an expiration date, and no one knows when. A healthy person could be gone tomorrow.
A neighbor and friend got diagnosed about 20 years ago. She was pregnant at the time and was told treatment would end the pregnancy, but if she didn;t get treatment, she would be lucky to live long enough to carry the baby to term. and by then treatment would not help and she likely wouldn't survive a year from the diagnosis date.
She didn't take treatment, had a healthy daughter and a few years later another healthy child and all are still alive today.
That's an exceptional case, but I do want you to know that you and Suzu have always been two of my all-time favorite posters here. Just a calm confident humility that I think is so inspiring and so few people ever achieve. You've responded to this challenge just as I would expect you would. If it is a brave face, I continue to pray for peace for you at any times when pain or fear is the devil you have to fight.
You will continue to be in my thoughts and prayers. I hope I face my challenges half as well as you.
