Jimmy Carter: 'Scans Show No Signs of Brain Cancer'

Former President Jimmy Carter says his latest scans show no signs of cancer.

Carter made the announcement at a Sunday school class he was teaching at Maranatha Baptist Church in Plains, Georgia.

"The church, everybody here, just erupted in applause," Jill Stuckey, a friend, told the Atlanta Journal-Constitution.

In August, the 91-year-old revealed that doctors had found four small melanoma lesions on his brain as well as one on his liver. He received a round of radiation targeted at those tumors and regular doses of Keytruda.

Carter has remained active during treatment, continuing his humanitarian work and volunteering with Habitat for Humanity.

Now doctors at Emory University's Winship Cancer Insititue say recent tests show no signs of the previous cancer "spots" and no evidence of new malignancy.

"It doesn't mean that there is no cancer in his body; it means that there is no indication that they can find cancer for the present," Dr. Len Lichtenfeld, deputy chief medical officer for the Atlanta-based American Cancer Society, told the Journal-Constitution.

Carter said he will continue to receive does of Keytruda to help his body seek out cancer cells.
