Former US President Jimmy Carter has revealed he is suffering with cancer.

In a statement the 90-year-old 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.

"A more complete public statement will be made when facts are known, possibly next week," the former president said through his foundation, The Carter Centre.

Carter, 90, underwent surgery earlier this month to remove a small mass in his liver.

The former peanut farmer and ex-Georgia governor was the nation's 39th president from 1977-81.

After leaving the White House he remained active in carrying out humanitarian efforts with the Carter Centre.

Founded in 1982, the Atlanta centre works to promote health care, democracy and other issues globally.

He recently finished a book tour to promote "A Full Life: Reflections at 90," his latest work of more than 20 books he has had published since leaving office.

As the news began trending, supporters of the former President took to social media to wish him well in his battle against the disease.
