Andrea Mitchell stunned viewers Wednesday when she announced live on-air that she has breast cancer.

Mitchell, who is NBC's chief foreign affairs correspondent, revealed the news at the end of her MSNBC show, 'Andrea Mitchell Reports.'

"And now a personal note, or how I spent my summer vacation: I had planned to be hiking in Wyoming last week," Mitchell said, "but instead discovered that I am now among the one in eight women in this country -- incredibly, one in eight -- who've had breast cancer."

Fortunately, said Mitchell, the cancer has been caught at an early stage. "Mine was discovered during my annual screening just a short time ago. Luckily for me, I'm one of the fortunate ones. We discovered it in the earliest stage, it had not spread, and I'm already back at work with a terrific prognosis."

NBC News reporter Andrea Mitchell is now making headlines of her own.

According to the AP, out of all the network evening news reporters, Mitchell clocked in the most minutes on camera during the last decade. Her total: a staggering 2,416 minutes.

Robert Bazell, also of NBC, finished in second, with 2,328 minutes.

Thankfully, NBC has decided once again to do different election coverage than their kissing cousins at MSNBC. So instead of David Gregory trying to moderate slap fights between Keith Olbermann, Joe Scarborough, and Chris Matthews, we get the relatively dignified analysis of Brian Williams, Chuck Todd, Tom Brokaw, Andrea Mitchell and Ann Curry. Whew. Looks like I selected the right network.

Some observations from the first couple of hours of coverage:

• Chuck Todd really has to shave his goatee. Yes, it was nice for awhile. But he might be the host of Meet the Press after this election is over; how can any one take him seriously with that "look, Ma, I can grow a beard!" look?
• Ann Curry is doing exit polling in a green room. Not a green screen, mind you, but an entire green room. It's freaky. Williams wanted to assure us that Curry was safe from those flying graphics. Nice of him.
• Does Williams have to remind us of his blue-collar, fire-fightin', hard-drinkin' past at every turn? "It's probably not a good thing that I know where Finnegans' Wake (a bar in Philly that's Obama's HQ there) is" he says to Mike Taibbi. Thanks for the insight into your past, Bri.

I'm sure a lot of you were scratching your heads over the weekend, wondering how Tim Russert's passing merited the all-encompassing, presidential-like coverage it got, especially on his home network of NBC. He's only a reporter, right? Why the wall-to-wall coverage? Well, first of all, it seems that by all accounts, Russert was one of the most well-liked people in the news business, so the outpouring might have been a function of people mourning a friend who was taken from them too soon. But, I have another, more off-beat theory as to why NBC did a broadcast version of sitting shiva for Russert: it was because they have no idea how to replace him.

Think about it: he wasn't only the longtime moderator of Meet The Press, where he took the venerable show and rejiggered its format, making him the face of the show. He was also NBC News' Washington bureau chief and the main political voice for the network. "It's going to take four or five people to replace Tim," CBS' Bob Schieffer told The New York Times.

For now, though, the immediate question is who will replace him on Meet The Press. Speculation is already underway.
