Home again!
Here are the grisly details.
It was understood that the op would be abandoned if possibility of cancer in the artery.
He was able to clear the artery but not the vein so it was abandoned.
I was under for 6 hours, 3 of which was working on the vein.
He took many samples from all the nearby tissues and organs, and no cancer was found.
That makes this a good news story, and very unusual.

I will be checked for any regrowth every few months, and I should have a reasonable life expectancy now.
That is a remarkable reversal of what I have been living with the last year and a half.

I am very weak and sore fro the op., but much better than I was.  I should be back to normal (?) in a few weeks or months.
Anyway, I am safely home and being well looked after.

Thanks for all your concern, kind thoughts and prayers.
They worked!
Keith and Mary.
