Former President Jimmy Carter just revealed that he has been diagnosed with cancer.

He posted a statement about the diagnosis on the website of The Carter Center on Wednesday.

“Recent liver surgery revealed that I have cancer that now is in other parts of my body. I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare,” Carter wrote. “A more complete public statement will be made when facts are known, possibly next week.”

Among other well-wishers, President Barack Obama called Carter to wish him a full recovery, the White House said. Vice President Joe Biden also spoke with Carter.

Carter, 90, was the 39th President of the United States.
