Jimmy Carter's cancer is gone, the former president announced on Sunday, December 6.

"My most recent MRI brain scan did not reveal any signs of the original cancer spots nor any new ones," he said in a statement posted on The Carter Center's Facebook page on Sunday. "I will continue to receive regular 3-week immunotherapy treatments of pembrolizumab."

The former president had revealed in August that medics had removed melanoma from his liver and discovered four small tumors on his brain. and that he was commenced on months of radiation treatments and injections to fight its spread.

He said his fate "is in the hands of God, whom I worship."

The 91-year-old, former president, initially made the announcement near the beginning of the Sunday School class Carter was teaching at Maranatha Baptist Church in Plains. NBC News reported.

"When I went (for an MRI) this week they didn't find any cancer at all," he said, as seen in a video posted by the outlet, drawing gasps and applause. "So I have good news. So a lot of people prayed for me, and I appreciate that."

Bill Clinton, the 42nd President of the United States was one of many well-wishers to send a message of support to Carter after the political veteran first shared he was suffering from cancer.

In a message on Twitter, Bill Clinton said that he is sending his 'thoughts and prayers' while wishing the Nobel Peace Prize winner 'a speedy recovery'.

Carter - a Georgia Democrat - won the Nobel Peace prize for his commitment to finding peaceful solutions to international conflicts and his work with human rights and democracy initiatives.

The Food and Drug Administration gave Keytruda - accelerated approval in 2014 for patients, like Carter, whose melanoma has spread.

It was in the basis of a big study that showed Keytruda is a prescription medication used to treat melanoma. It is also used to treat advanced non-small cell lung cancer.
