Former U.S. President Jimmy Carter underwent surgery on Monday to remove a small mass from his liver and has an excellent prognosis, the Carter Center announced.
The center said the surgery to remove the mass was elective. The operation took place at Emory University Hospital.
“His operation proceeded without issues, and the prognosis is excellent for a full recovery,” the center said in a statement.
Carter, 90, served as president from 1977 to 1981. Prior to becoming the 39th president, he was the governor of Georgia and a state senator.
He emerged on the national scene as a presidential contender, telling Americans he would never lie to them and striking populist tones, in the aftermath of the Watergate scandal that brought down President Richard M. Nixon in 1974.
Carter in recent decades has focused on diplomacy, fair elections, affordable housing and other issues through his Carter Center, which he and his wife Rosalynn founded in 1982.
Carter, a former peanut farmer from Plains, Ga., has been on tour to promote his new book “A Full Life: Reflections at 90.” He is now the second oldest-living president after George H. W. Bush, who is 91.
