The 90-year-old Carter gave one lesson to about 300 people filling the small Baptist church that he and his wife, Rosalynn, attend. It was Carter's first lesson since detailing the intravenous drug doses and radiation treatment planned to treat melanoma found in his brain after surgery to remove a tumor from his liver.
