Supreme Court Justice Ruth Bader Ginsburg has canceled appearances at events in Los Angeles and New York in the upcoming weeks following surgery in December to remove cancerous nodules from her lung, CNN reports.

"Supreme Court Justice Ruth Bader Ginsburg regrets that she is unable to attend the talk with David Rubenstein at 92Y on Feb. 6," the 92nd Street Y in Manhattan wrote in an email to CNN. "She is curtailing travel and focusing on her work while recuperating from recent surgery."

Ginsburg was also scheduled to appear at Los Angeles' Skirball Cultural Center on Jan. 29.

The 85-year-old jurist missed two weeks of oral arguments following surgery, her first time in over 25 years, but has still participated in court cases by reading briefs at home.

"Justice Ginsburg will continue to work from home next week and will participate in the consideration and decision of the cases on the basis of the briefs and the transcripts of oral arguments. Her recovery from surgery is on track," Supreme Court Spokeswoman Kathy Arberg said Friday.

"Post-surgery evaluation indicates no evidence of remaining disease, and no further treatment is required."

Ginsburg, the oldest justice on the bench, has survived cancer twice before.
