I'm deeply sorry about your situation, Llance. You've been missed from these boards, but obviously you've had greater concerns than posting here regularly.
I have a beautiful co-worker (and very kind) who was diagnosed with breast cancer three years ago, and went through chemotherapy and as of roughly 2 years ago is now fully recovered. I have an aunt who in her late 60's developed lymphoma and likewise went through chemotherapy and was fully recovered for 10 years until she eventually died something else, heart disease.
So there's hope.
I had a minor skin cancer myself in December of last year, removed from above my right cheekbone and below the eye. I was a bit afraid I'd been butchered in the two weeks immediately after, I joked I looked like Frankenstein. But two days after the stitches were removed, it was barely even noticeable, and is virtually invisible now.
I've seen it written often that over 90% of cancers are treatable, the key is to catch it early.
Best wishes Llance, and hope to hear good news from you in the near future.
