Mary Tyler Moore underwent a four-hour operation to remove a benign tumor on the lining tissue of the skull, her rep tells PEOPLE.
“According to her surgeon, she tolerated the procedure without difficulty and is recovering nicely with her husband at her bedside,” the rep says.
In what was described as a fairly routine procedure, the tumor, called a meningioma, was entirely removed, and the actress, 73, is “will require no additional treatment,” the rep adds. – Julie Jordan
