After being treated with IV antibiotics and fluids, Ginsburg's symptoms subsided, and doctors say she's likely to be released from the hospital on Sunday.
In 1999, she successfully underwent surgery to treat colon cancer, before being diagnosed with the early stages of pancreatic cancer a decade later.
Ginsburg's treatment for the tumor on her pancreas began on August 5, days after it was discovered, according to the court's announcement. During her hospitalization she had a bile duct stent placed.
Her most recent diagnosis did little to derail her active public speaking schedule though, as she chose to embark on a multi-state tour. The tumor was treated definitively and there is no evidence of disease elsewhere in the body. Since Ginsburg first got on the Court, two other females-Sonia Sotomayor and Elena Kagan-have been appointed, and still serve today.

'This latest has been my fourth cancer battle and I found each time that when I'm active, I'm much better than if I'm just lying about and feeling sorry for myself, ' she said in September, in NY, at an event hosted by Moment Magazine. "It is the best and hardest job that I ever had".
Ginsburg has had four occurrences of cancer, including two in the past year.
Ginsburg added, "I have to somehow surmount whatever is going on in my body and concentrate on the court's work".
