Former US President Jimmy Carter has announced that his brain cancer is gone.
His grandson Jason Carter told AP news agency that his grandfather said doctors "couldn't find any cancer in his most recent scan''.
The Atlanta Journal-Constitution (AJC) newspaper said the 91-year-old also said he was free of cancer during a Sunday school class in Plains, Georgia.
Mr Carter, who was president from 1977 to 1981 and won a Nobel Peace Prize in 2002, revealed his illness in August.
Doctors have been treating four small melanoma lesions on his brain.
Last month, Mr Carter said he was responding well to treatment and there were no signs of further cancer growth.
Jill Stuckey, a member of the congregation at Maranatha Baptist Church in Plains, told AJC that Mr Carter had been teaching the class of about 350 people when he made the announcement.
"He said he got a scan this week and the cancer was gone," she said.
"The church, everybody here, just erupted in applause."
US broadcaster NBC quoted Mr Carter as saying: "Went for an MRI this past week and they (doctors) didn't find any cancer at all in the brain."
Mr Carter revealed in August that cancer initially found in his liver had spread to four spots on his brain. The lesion on his liver was removed on 12 August.
After leaving the White House, Mr Carter founded the Carter Center, which focuses on human-rights efforts and political mediation.
He has remained active with the centre ever since.
Mr Carter - a Georgia Democrat - won the Nobel Peace prize for his commitment to finding peaceful solutions to international conflicts and his work with human rights and democracy initiatives.
