Jimmy Carter revealed outside of the Sunday School class at Marantha Baptist Church in his hometown of Plains, Ga. that he is now cancer-free, according to ABC News. "Went for an MRI this past week and [doctors] didn't find any cancer at all in the brain," Carter said.

The announcement follows about four months after Carter revealed that doctors had found four spots of cancer that had spread from his liver to his brain. The former president has undergone radiation to combat the melanoma.

Carter had an MRI last week, with the scan revealing that the cancer is gone, according to Stephanie Wynn, a member of the Marantha Baptist Church, and the congregation applauded when they heard the news.

And yet, Carter, 91, continues business as usual, teaching the Sunday School class just three days after the happy news, according to CNN.

"Well, I always explain to the class where I've been the past couple of weeks," Carter told the class when he found he had cancer. "I missed two lessons because toward the end of May (and) first of June it was found that I had cancer, so they removed part of my liver," he added. "But then we had another MRI and it showed I have four places in my brain."

After treatment, better news came to the congregation.

"My most recent MRI brain scan did not reveal any signs of the original cancer spots nor any new ones," Carter said in a press release, according Mashable. "I will continue to receive regular 3-week immunotherapy treatments of pembrolizumab."
