Former President Jimmy Carter said Sunday that an MRI scan earlier in the week showed his cancer is gone.
Carter, 91, announced the good news to attendees of a Sunday school class he often teaches at Maranatha Baptist Church in Plains, Georgia.
"Went for an MRI this past week and they (doctors) didn't find any cancer at all in the brain," Carter said.

Carter revealed in August that he would undergo radiation treatment for several melanoma spots on his brain and liver after he learned a mass removed from his liver was melanoma. Later in August, Carter began a new drug, known as Keytruda, that had proved promising in other patients. "I'll be prepared for anything that comes," he said at the time.
Last month, the 39th president said he was feeling well, and tests showed the cancer had not spread any further, the Carter Center, a nonprofit organization he set up after leaving the presidency, said in a statement.
Carter has stayed active during his treatment. He taught his Sunday school class days after announcing his diagnosis and even spent time building houses with Habitat for Humanity, an organization that he has worked closely with since 1984.
