Former U.S. President Jimmy Carter said that a scan of his torso conducted last week found no signs of melanoma, the serious form of cancer that doctors discovered last summer in his liver and brain, but he will continue treatment on February 9th.

A previous brain scan found that four cancerous lesions were gone with no new evidence of new cancer cells, Carter said in December.

Carter spoke on the phone to South Sudan from London where he is speaking about his campaign against Guinea worm disease, a painful affliction which his foundation the Carter Center has worked since 1986 to eradicate.
