Former U.S. President Jimmy Carter announced Wednesday that he has cancer, and the disease has spread to several parts of his body.
"I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare," Carter said in a statement. "A more complete public statement will be made when facts are known, possibly next week."
The cancer was discovered while Carter was undergoing liver surgery. The elective procedure removed a small mass, 11 Alive reported on Aug. 3.
Carter, who is 90, served as president from 1977 to 1981. In 2002, he was awarded the Nobel Peace Prize, and he recently published a memoir, A Full Life, on his early years in rural Georgia, his time as president, and his later work as a humanitarian.
In May, Carter cut short a trip to Guyana because he was not feeling well.
A 2010 book tour was also briefly interrupted when Carter was hospitalized as a precaution.
