I have no idea what you are going through, I don't pretend to, and only wish jerryskids the best.
With that said, my wife's best friend was diagnosed with late (I think 3) stage colon cancer that metastasized to her liver and lungs. This was six years ago. She was over tonight hanging out with us and looked better than ever, you would never know. Don't get me wrong, she's had multiple surgeries, chemo, all the things. However she is doing great, the cancer is "at bay" if you will, but modern medicine is amazing. Even if this spread to other organs you caught it way early and that is treatable.
I see no reason you cannot battle this and win. You're a smart dude with a great support system. Give it hell Jerry.
