Justice Ruth Bader Ginsburg underwent a pulmonary lobectomy today at Memorial Sloan Kettering Cancer Center in New York City. Two nodules in the lower lobe of her left lung were discovered incidentally during tests performed at George Washington University Hospital to diagnose and treat rib fractures sustained in a fall on November 7. According to the thoracic surgeon, Valerie W. Rusch, MD, FACS, both nodules removed during surgery were found to be malignant on initial pathology evaluation. Post-surgery, there was no evidence of any remaining disease. Scans performed before surgery indicated no evidence of disease elsewhere in the body. Currently, no further treatment is planned. Justice Ginsburg is resting comfortably and is expected to remain in the hospital for a few days. Updates will be provided as they become available.
