Former President Jimmy Carter revealed he has been diagnosed with cancer on Wednesday.
"Recent liver surgery revealed that I have cancer that now is in other parts of my body," Carter, 90, said in a statement. "I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare. A more complete public statement will be made when facts are known, possibly next week."
Carter, who was the 39th president, underwent surgery on Aug. 3 to remove a mass in his liver. That is when doctors discovered the cancer, though Carter did not specify what type of cancer it is.
Carter is one of only four living former presidents and has stayed active since his presidency through the Carter Center, which he established after leaving the White House in 1981. In July, Carter published his most recent book, A Full Life: Reflections at 90.
