ATLANTA - Jimmy Carter's grandson says no cancer was detected the last time the former president underwent a scan.

Jason Carter told The Associated Press in a text message that his grandfather "told me that the doctors couldn't find any cancer in his most recent scan."

It was not immediately known when the scan took place, or when Carter received the news from his grandfather.

The elder Carter apparently shared the good news before giving a Sunday School lesson at Maranatha Baptist Church in his hometown of Plains, Georgia. Jill Stuckey, a church leader who was present, said Carter had announced that a brain scan this week showed no cancer.

Carter, 91, announced in August that he had been diagnosed with melanoma that spread to his brain.
