Actress Mary Tyler Moore had a four-hour brain operation to remove a benign tumor and is "recovering nicely," her spokeswoman said on Friday.
The beloved actress, 74, had elective surgery to remove what is known as a meningioma, or benign tumor of the lining tissue of her brain. She had previously lived with the condition for years.
"Mary Tyler Moore underwent a four hour procedure...The tumor was resected in its entirety and she will require no additional treatment," Moore's spokeswoman said in a statement.
"According to her surgeon, she tolerated the procedure without difficulty and is recovering nicely with her husband at her bedside," the statement said. It did not say when or where the surgery took place.
Moore is best known for her role as the perky 1960s housewife of comedian Dick Van Dyke in "The Dick Van Dyke Show" and as the liberated single working woman in "The Mary Tyler Moore Show" in the 1970s.
She was also Oscar-nominated for her performance as an icy mother struggling to connect with her son in the 1980 movie "Ordinary People".
Moore was seen on the daytime TV talk show "Rachel Ray" on Thursday in a pre-taped appearance, chatting and laughing with Van Dyke who is promoting his recent autobiography.
Meningioma is a tumor that arises in the membranes surrounding the brain and are usually non-cancerous, according to the Mayo Clinic. They occur mostly in older women and can exist for years without showing significant symptoms.
