The specimen, a tubular adenoma, was similar to one removed from Biden in 2008, Dr. Kevin C. O’Connor, physician to the president, wrote in a memo released Wednesday by the White House. Routine surveillance, which normally calls for another colonoscopy in seven to 10 years, was recommended, he wrote.

Joe Biden visited Walter Reed Medical Center on Friday for a colonoscopy and routine medical check-up.

Biden, who turned 79 last week and is the nation’s oldest president, remains “healthy” and “vigorous” and fit for duty, O’Connor said in his initial report after Biden’s first routine physical in office.
