Doctors removed five small growths from President George W. Bush's colon Saturday after he temporarily transferred the powers of his office to Vice President Dick Cheney under the rarely invoked 25th Amendment of the US Constitution. The polyps, extra tissue growing inside his large intestine, were found during a routine colon cancer scan performed at the Camp David presidential retreat. "All were less than 1 centimeter (about four-tenths of an inch) and none appeared worrisome," White House spokesman Scott Stanzel said. Outside medical experts agreed. The polyps were sent to the National Naval Medical Center in Bethesda, Maryland, to be microscopically examined for signs of cancer. Results were expected in 48 hours to 72 hours. Polyps can turn cancerous, so finding them early is one of the best ways to prevent the disease and improve the odds of surviving it.
