Carter Center

A statement issued Tuesday by the Carter Center says the 90-year-old will address reporters Thursday morning in Atlanta.

Carter revealed on Wednesday that he had been diagnosed with cancer.

In a brief statement, he said a surgery to remove a small mass from his liver had revealed cancer that had spread to other parts of his body. He said he planned to undergo treatment at Emory Healthcare in Atlanta and promised more details soon.

A statement released by Carter's spokeswoman Deanna Congileo described Monday's operation at Emory University Hospital in Atlanta as an elective procedure.

It said the procedure was done without issues, and that the prognosis "is excellent for a full recovery." The Carter Center's statement offered no other details.

Carter was the nation's 39th president. The native of Plains, Georgia, is also a former Georgia governor.
