Ruth Bader Ginsburg, the eldest justice on the US Supreme Court, underwent surgery on Friday to remove two malignant nodules on her left lung, the court announced, according to AFP.
Ginsburg, 85, underwent the pulmonary lobectomy at Memorial Sloan Kettering Cancer Center in New York.
"Both nodules removed during surgery were found to be malignant on initial pathology evaluation," the court said.
"Post-surgery, there was no evidence of any remaining disease," it added.
"Scans performed before surgery indicated no evidence of disease elsewhere in the body. Currently, no further treatment is planned."
The court said Ginsburg was "resting comfortably" and would remain in the hospital for "a few days."
The nodules were discovered last month in x-rays that Ginsburg underwent after she fell and fractured three ribs.
The Jewish judge was discharged from the hospital the next day and was back at her notoriously vigorous workouts within a week.
The justice, who was appointed by President Bill Clinton in 1993, is one of four liberals on the nine-member court.
Since taking office, President Donald Trump has had the opportunity to replace two retiring justices, tipping the balance in the conservatives' favor.
Ginsburg had a fall out with Trump before he was elected, when she said in interviews "can't imagine what the country would be" with Trump as president.
She later acknowledged her comments were “ill-advised” and added, “Judges should avoid commenting on a candidate for public office. In the future I will be more circumspect.”
The court's oldest justice, Ginsburg is a liberal stalwart who has said she will not retire as long as she feels she can do the work.
