Former President Jimmy Carter has announced that his cancer is "gone" after being diagnosed with the disease over the summer.

In a statement to BuzzFeed News, the former president said that he received news that his brain was clear of cancer after a recent scan.

"My most recent MRI brain scan did not reveal any signs of the original cancer spots nor any new ones," he said, adding he will continue immunotherapy treatments.

Carter first made the announcement while teaching a Sunday School class at his church in Georgia, the Atlanta Journal-Constitution reported.

The Jimmy Carter Library later shared the newspaper's article on its official Twitter account.

Jill Stuckey, a friend of Carter's and a fellow member of the Maranatha Baptist Church, told the newspaper that the former president told the group "he got a scan this week and the cancer was gone."

"The church, everybody here, just erupted in applause," she said.

She said about 350 people were in the room when he made the announcement.

The 91-year-old announced in August that doctors discovered he had cancer when he was having liver surgery.

But last month the Carter Center announced that the former president had received "good news" from his doctors.

"They tell him that recent tests have shown there is no evidence of new malignancy, and his original problem is responding well to treatment," the center said in a statement.

The statement said Carter would be having further tests done.

The Carter Center did not respond to a request for comment from BuzzFeed News.
