Schieffer talks to Couric about his cancer

We're interrupting the fun and frolic from the Television Critics Association summer meetings to bring you this brief public service announcement:

"Face the Nation" anchor Bob Schieffer will be talking about his brush with bladder cancer tonight on "The CBS Evening News with Katie Couric" (6:30 p.m., Channel 3) as part of a story to raise awareness of the disease, which in 95 percent of the cases first shows up as blood in the urine, according to CBS.

It appears Schieffer's cancer was caught early, allowing a treatment that saved his bladder.

Model Patti Hansen, the wife of Rolling Stones guitarist Keith Richards, who's recently been speaking out her own fight against bladder cancer three years ago, also is scheduled to appear.

Update: Apparently not to be outdone, Vanity Fair contributing editor Christopher Hitchens (and author of the skeptical tome, "God Is Not Great") will appear on CNN's "Anderson Cooper 360" at 10 tonight to talk about his recent cancer diagnosis.
