A spokesman says doctors removed five small polyps during a colonoscopy and that none appears to be "worrisome."
The 31 minute procedure was performed at Camp David.
President Bush temporarily transferred the powers of his office to Vice President Dick Cheney at 7:16, Eastern time, Saturday morning, and reclaimed his authority about two hours later.
The polyps were less than a centimeter and were sent for further
Friday, the president's press secretary said there was a reasonable chance that polyps would be found. Although none were detected five years ago during the president's last exam, he did have them in 1998 and 1999, making President Bush a candidate for more frequent screenings.
