My wife is recovering from having her right lung completely removed. She was one of the lucky ones- hers was found in a routine chest x-ray before she started showing symptoms, and they were able to remove the tumor before it spread. Most are not that lucky. Her chemo was bad, but it's been 2 1/2 years since she finished it, and so far all of her scans have been good.
I thought I had lost her when she was diagnosed. She's not the same as before, but at least she's still with me! Very sorry for your situation, Doc. I know it's tough. My brother, my lifelong best friend, had terminal colon cancer, and has now passed on as of two years ago.
Life may never again be like it was, but life is still good. Hang in there, Doc, this too will pass. There is life after death, even for the living.
