A spokesperson for Mary Tyler Moore says the sitcom star is "recovering nicely" after undergoing a four-hour surgery to remove a benign tumor on the lining of her brain, according People magazine.
The procedure was to remove a meningioma, a slow-growing tumor in the membranes that cover the brain.
"According to her surgeon, she tolerated the procedure without difficulty and is recovering nicely with her husband at her bedside," the spokesperson told the magazine.
It was announced on Thursday that the 73-year-old actress was set to go under the knife.
"Mary Tyler Moore went in for an elective surgery to remove a meningioma, which is a benign tumor of the lining tissue of the brain (not a brain tumor). At the recommendation of her neurologist, who has been monitoring this for years, and a neurosurgeon, Mary decided to proceed with this fairly routine procedure," the publicist said in a statement to OnTheRedCarpet.com.
Moore is known for her roles in "The Dick Van Dyke Show" in the 1960s and "The Mary Tyler Moore Show" in the 1970s. In the latter, she played Mary Richards, a local news producer in Minneapolis.
After "Mary Tyler Moore" ended in 1977, Moore went on to star in shows such as "The Naked Truth," "That '70s Show" and "Lipstick Jungle."
Earlier this year, Moore reunited with her former "Mary Tyler Moore" co-star Betty White on the second season premiere of the comedy series "Hot in Cleveland" after more than 33 years.
