Supreme Court Justice Ruth Bader Ginsburg, 85, underwent surgery Friday to remove two malignant nodules from her left lung, the Supreme Court said.

It said she was "resting comfortably" after the surgery at Memorial Sloan Kettering Cancer Center in New York, and there was no evidence of any remaining disease.

"Currently, no further treatment is planned," the court said in a statement.

Ginsburg, the eldest member of the court and the senior justice of its liberal wing, underwent a pulmonary lobectomy. Two nodules in the lower lobe of her left lung were discovered incidentally during tests she received while being treated for rib fractures sustained in a fall last month. Both nodules were found to be malignant during an initial evaluation.

Sloan Kettering on its website describes a lobectomy as the most common operation for non-small cell lung cancer. It is the best treatment for "isolated lung cancer in an otherwise healthy patient," according to the hospital.

Ginsburg was recovering from three rib fractures she sustained after falling in her office on Nov. 7. On Saturday, she told an audience in New York that she was "almost repaired" and had returned to doing her full workouts with her physical trainer after initially limiting her workouts to her lower body. Ginsburg did not miss any oral arguments because of her injury.
