Former President Jimmy Carter has been diagnosed with cancer.
The 90-year-old politician announced made the heartbreaking announcement on Wednesday, just weeks after having a small mass removed from his liver.
He said: '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.'
The statement released Wednesday makes clear that Carter's cancer is widely spread, but not where it originated.

Dr. Len Lichtenfeld, deputy chief medical officer of the American Cancer Society, says 'Our thoughts and prayers go out to President Carter.'
Lichtenfeld says, 'There's a lot we don't know,' but the first task likely will be determining where the cancer originated, as that can help determine what treatment he may be eligible for.
'Sometimes the primary site can't be determined, so genetic analysis of the tumor might be done to see what mutations are driving it and what drugs might target those mutations.
He adds, 'Given the president's age, any treatments, their potential and their impacts, will undoubtedly be discussed carefully with him and his family.'
President Obama released a statement supporting Carter, adding that America is 'rooting' for him.
He said: 'Michelle and I send our best wishes to President Carter for a fast and full recovery. Our thoughts and prayers are with Rosalynn and the entire Carter family as they face this challenge with the same grace and determination they have shown so many times before.
'Jimmy, you're as resilient as they come, and along with the rest of America, we are rooting for you.'
The liver is often a place where cancer spreads and less commonly is the primary source of it. It said further information will be provided when more facts are known, 'possibly next week.'
