WASHINGTON — Justice Ruth Bader Ginsburg said Friday she's being treated for a recurrence of liver cancer and plans to remain on the Supreme Court.
The 87-year-old justice, a cultural icon and leader of the progressive wing, said she began a course of chemotherapy on May 19 after a scan in February and a biopsy found lesions on her liver.
"Immunotherapy first essayed proved unsuccessful. The chemotherapy course, however, is yielding positive results," Ginsburg said in a statement provided by the Supreme Court.
"My most recent scan on July 7 indicated significant reduction of the liver lesions and no new disease. I am tolerating chemotherapy well and am encouraged by the success of my current treatment. I will continue bi-weekly chemotherapy to keep my cancer at bay, and am able to maintain an active daily routine," she continued.
Ginsburg has been treated for cancer four times before. She had surgery for pancreatic cancer 11 years ago and has also been treated for colon cancer. In late 2018, part of a lung was removed after doctors found three cancerous spots.
Ginsburg continued to write Supreme Court opinions through the term that ended earlier this month, authoring more than any of the other justices except Chief Justice John Roberts and Justice Brett Kavanaugh.
She said she intends to keep working.
"Throughout, I have kept up with opinion writing and all other Court work," she said. "I have often said I would remain a member of the Court as long as I can do the job full steam. I remain fully able to do that."
She was nominated by President Bill Clinton in 1993. Her future has been the subject of much speculation on a court that has been closely divided on numerous major issues.
