Former U.S. first lady Rosalynn Carter is recovering at Emory University Hospital from successful surgery Sunday to remove scar tissue from her lower intestine, The Carter Center said in a statement.
The scar tissue had formed in the area from where a cyst was removed several years ago, the statement said.
The former first lady, 90, who married President Jimmy Carter on July 7, 1946, in Plains, Ga., emerged as a driving force for mental health during his administration.
She is expected to be hospitalized for several days.
In August 2015, President Carter announced he had metastatic melanoma that had spread to his liver and brain. After undergoing surgery, radiation and a breakthrough treatment called immunotherapy, he was declared cancer-free in March 2016.
