Washington (CNN) Supreme Court Justice Ruth Bader Ginsburg said she's on her way "to being very well" after receiving treatment for pancreatic cancer.

Speaking at the 2019 Library of Congress National Book Festival, Ginsburg told a crowd gathered in Washington, DC, on Saturday, "As this audience can see I am alive. And I'm on my way to being very well." She was met with thunderous applause.

The US Supreme Court announced on August 23 that physicians had discovered a malignancy on Ginsburg's pancreas and that she subsequently had three weeks of radiation treatment. "The tumor was treated definitively and there is no evidence of disease elsewhere in the body," the court said. Despite the treatment, the 86-year-old has made a series of recent public appearances and continues to travel.

Ginsburg told the crowd Saturday that she'll be ready for the start of the next Supreme Court session, saying, "We have more than a month yet to go. I will be prepared when the time comes.'
