The Carter Center in Atlanta has sent this out:
Former U.S. President Jimmy Carter underwent an elective procedure at Emory University Hospital today to remove a small mass in his liver. His operation proceeded without issues, and the prognosis is excellent for a full recovery.
A spokewoman for the Carter Center refused to say whether Carter is still in hospital. But the Associated Press included this in its report:
Julia Prosser with the publisher Simon & Schuster said Carter completed a tour Saturday promoting his latest book, "A Full Life: Reflections at 90."
