Supreme Court Justice Ruth Bader Ginsburg said in a statement Friday she is undergoing chemotherapy treatments to treat a "recurrence of cancer." Ginsburg, 87, said in the statement she began treatment May 19 after a biopsy showed she had lesions on her liver. She said a July 7 scan showed there was a "significant reduction" in her liver lesions "and no new disease." Ginsburg also indicated that she is "fully able" to continue her capacity as a member of the Supreme Court.
