Jimmy Carter says he feels fine, keeps busy despite cancer

MEMPHIS, Tenn. (AP) – Jimmy Carter says it’s too soon to tell whether treatment he received has been effective against cancer on his brain.

But the 91-year-old former U.S. president tells The Associated Press he hasn’t been uncomfortable or ill while receiving rounds of immune-boosting drugs to help fight the illness.

Carter spoke to the AP on Sunday, hours before participating in a Habitat for Humanity home-building effort Monday in Memphis, Tennessee. He also will announce the organization’s plans to return in August for a week-long effort. Carter and his wife, Rosalynn, have volunteered a week annually since 1984 with the Atlanta-based charity.

Carter says his health hasn’t forced him to cut back on work with Habitat or at The Carter Center, a human rights organization he founded after leaving the White House.
