(Newser) – President Bush will undergo a routine colon exam tomorrow, leaving Dick Cheney in the driver's seat for roughly 2½ hours while he's under anesthesia. Bush's personal physician will supervise the procedure, in the medical facility at Camp David. This will be the second time the VP has acted as president; the first was during Bush's last colonoscopy, in 2002.

The president had colon polyps removed before his election; press secretary Snow said today "there's a reasonable chance" doctors will find more of the growths during the colorectal-cancer screening, Reuters reports. Snow, who is undergoing treatment for colon cancer, told reporters, "The president wants to encourage everybody to use surveillance," CNN reports.
