Supreme Court Justice Ruth Bader Ginsburg will miss a second week of oral arguments as she continues to recover from cancer surgery she underwent last month, court spokeswoman Kathy Arberg said Friday.

But Ginsburg's recovery is on track, there is no evidence of remaining cancer in her body and no further treatment is planned. Ginsburg will continue to participate in the cases on the basis of the briefs and transcripts of oral arguments.

"Her recovery from surgery is on track," Arberg said. "Post-surgery evaluation indicates no evidence of remaining disease, and no further treatment is required."

Ginsburg underwent an operation on Dec. 21 to remove two cancerous growths from her left lung. Friday marks three weeks since the surgery. Ginsburg, the court's eldest justice, will turn 86 in March.
