When a man lives to be 90 years old, he has reached to the age where it is time to come to terms with his life, what he has done, and the final things he will end up doing. For Jimmy Carter, one of those things is dealing with cancer, recently discovered when he had a mass removed from his liver earlier this August. In a brief statement, he explained that “recent liver surgery revealed I have cancer, that is now in other parts of my body.”

With this news, well wishes have come pouring in from all sides, including from President Barack Obama himself. “Our thoughts and prayers are with Rosalynn and the entire Carter family as they face this challenge with the same grace and determination that 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.”

People have been blowing up Twitter with get well soon notes to Carter, a few notables being former Florida Governor Jeb Bush, Apple CEO Tim Cook, and actress Mia Farrow.

Carter was elected to a single term in 1976, but was subsequently defeated by Ronald Reagan in the 1980 election. However, he is still often discussed in the political world; 2016 Republican Presidential Candidates Rick Perry and Ted Cruz frequently request Carter to suggest that the nation can recover from liberal leadership.

Despite his age, Carter has been relatively healthy up until May, when he had to cut a trip to Guyana short due to an illness.

In a remarkable press conference marked by grace and devoid of self-pity, former President Jimmy Carter said Thursday that four spots of cancer had spread to his brain. Carter’s family has a history with pancreatic cancer. He has lost his father, sister, and two brothers to the disease. “If you’ve got pancreatic cancer, you die. Absolutely,” Carter told CNN’s Larry King in 2008.

Hopefully the former President will make a full recovery.
