For those who've been e-mailing and asking, I'm feeling much better now.
There's a bit of residual soreness, but the actual incision is nicely healed up. I may look like a rejected Frankenstein experiment, but the pain is mostly gone.
The official word from the docs is that the cancer was completely contained in the kidney. There's no indication that it has spread anywhere else, so the surgery should have taken care of everything. Now let's just keep hoping my remaining kidney continues functioning efficiently.
I'm slowly getting back to work (you'll have noticed that I'm posting stuff here fairly regularly again), and hope to start making up some time this week. I've got a lot on my plate... including my DVD Late Show column, which I'm hoping to re-launch before the end of the month.
Anyway, thanks to all for your good thoughts and well-wishes. Time to get back to work.
