Just days after undergoing a pulmonary lobectomy, Supreme Court Justice Ruth Bader Ginsburg is up and working.

Ginsburg, 85, continued working on Sunday while still at Memorial Sloan Kettering Cancer Center in New York City, according to Kathy Arberg, a spokeswoman for the court.

On Friday, Ginsburg underwent surgery to remove two malignant growths from her lungs. The cancerous nodes were incidentally discovered during tests related to her treatment for a Nov. 7 fall in which she broke three of her ribs.

Both "nodules removed during surgery were found to be malignant on initial pathology evaluation," the court said last week in a statement, but added 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,” the statement concluded.

It is unclear when Ginsburg will return back to Washington. The legendary women’s rights champion has never missed arguments, and the court next meets on Jan. 7.

This is Ginsburg's third bout of cancer, after surviving both colon and pancreatic cancer. She also had a heart stent procedure in 2014.

Ginsburg is known for her love of working out, training at least twice a week for at least an hour.

Ginsburg’s trainer Bryant Johnson told People magazine that she is eager to return to the gym: “Even this, she is going through this, she asked me, ‘When can we go back to training?’” “Her attitude is, ‘When is the next time I can work out?’ No matter what, it is, ‘When can we work out?’” Johnson said.

Prior to undergoing the procedure, Ginsburg voted against the Trump administration to reject its bid to allow enforcement of the asylum policy, which effectively prohibits asylum for migrants who illegally cross the southern border.
