Former President Jimmy Carter announced late Wednesday that cancer in his liver has now spread to other parts of his body.
Carter, 90, had undergone surgery to remove a "small mass" from his liver earlier this month. He received a prognosis of a full recovery at the time but announced Wednesday that "Recent liver surgery revealed that I have cancer that now is in other parts of my body."
Carter will now receive treatment for the illness at Emory University in Atlanta and will release more information next week.
It remains unclear the extent to which the disease has spread.
The popular ex-President's announcement was immediately greeted by an outpouring of support on Twitter and other social media platforms.
