Just more than one week after Jimmy Carter underwent surgery to remove a mass on his liver, the former president has revealed he has cancer.

The 90-year-old politician announced on Wednesday, Aug. 12 that he has been diagnosed with cancer that originated in his liver but has now spread to other parts of his body. The disease was discovered following his operation on Monday, Aug. 3.

"Recent liver surgery revealed that I have cancer that now is in other parts of my body," Jimmy said in a statement earlier this week. "I will be rearranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare."

Though it is still unclear exactly where the cancer has spread throughout his body, Jimmy said he plans to reveal more information about his condition "possibly by next week."
