Former U.S. President Jimmy Carter diagnosed with cancer

Former U.S. President Jimmy Carter has been diagnosed with cancer, according to a brief statement released by the Carter Center Wednesday.

"Recent liver surgery revealed that I have cancer that now is in other parts of my body," the statement reads. Carter, 90, had surgery earlier this month to remove a small mass in his liver.

He will immediately begin treatment at Emory Healthcare in Atlanta.

More details are expected to be released next week following more medical tests.

 Carter was the nation's 39th president and held office from 1977 to 1981. He is the oldest surviving United States president.
