Justice Ginsburg just successfully beat cancer again today. This woman is as strong as an ox.

Supreme Court Justice Ruth Bader Ginsburg is hanging in there for the sake of everyone and the further balance of the court.

Announced on Friday, she just completed three weeks of radiation treatment at Memorial Sloan Kettering Cancer Center in New York.

"The focused radiation treatment began on August 5 and was administered on an outpatient basis to treat a tumor on her pancreas. The abnormality was first detected after a routine blood test in early July, and a biopsy performed on July 31 at Sloan Kettering confirmed a localized malignant tumor."

"As part of her treatment, a bile duct stent was placed. The Justice tolerated treatment well. She cancelled her annual summer visit to Santa Fe, but has otherwise maintained an active schedule. The tumor was treated definitively and there is no evidence of disease elsewhere in the body. Justice Ginsburg will continue to have periodic blood tests and scans. No further treatment is needed at this time."

Ginsburg, age 86, is already one of the oldest living Supreme Court Justices in history. Only three people have had the good graces of living longer.

To put this in perspective, Billionaire conservative activist David Koch died at the age of 79 today.

“It is with a heavy heart that I announce the passing of my brother David," Charles Koch said in a statement Friday. "Anyone who worked with David surely experienced his giant personality and passion for life."

Ginsburg doesn't plan on that happening to her anytime soon. There has been rampant speculation of her retirement due to her ailing health conditions, but she dispelled any notion of that in an interview this summer.

She claims being on the Supreme Court keeps her going, actually, not the opposite.

"The work is really what saved me, because I had to concentrate on reading the briefs, doing a draft of an opinion, and I knew it had to get done. So I had to get past whatever my aches and pains were just to do the job."

She added, "There was a senator, I think it was after my pancreatic cancer, who announced with great glee that I was going to be dead within six months," she told Totenberg. "That senator, whose name I have forgotten, is now himself dead, and I am very much alive."

Previously Ginsburg said she wasn't going anywhere for "at least 5 years." She made that statement last summer.
