Supreme Court Justice Ruth Bader Ginsburg, the only woman currently serving on the nation's highest court, underwent surgery Thursday for removal of a cancerous tumor from her pancreas.
Ginsburg, 75, is being treated at Memorial Sloan-Kettering Cancer Center in New York.
Ginsburg has served on the court since 1993.
She was treated for colon cancer 10 years ago.
Ginsburg's pancreatic cancer was discovered early, in the course of a routine annual screening, but medical literature says even in this circumstance, a patient's five-year survival chances range from 10 to 30 percent.
