Supreme Court Justice Ruth Bader Ginsburg was seen leaning on a U.S. Marshal after leaving a New York City hospital, DailyMail.com exclusive photos show, a day before it was announced she had completed radiation treatment for a cancerous tumor on her pancreas.

The 86-year-old underwent three weeks of radiation treatment at Memorial Sloan Kettering hospital after a routine blood test led to the discovery of a localized malignant tumor last month, the U.S. Supreme Court announced on Friday.

The tumor was 'treated definitively and there is no evidence of disease elsewhere', and no further treatment is needed at this time, the statement said.

On Thursday, Ginsburg was seen holding the hand of a U.S. Marshal as she walked up the stairs into a private residence on the Upper East Side after her appointment at the Howard Laboratory at the Memorial Sloan Kettering hospital.

Ginsburg has been diagnosed with cancer three times already, colon cancer in 1999, pancreatic cancer in 2009 and lung cancer in 2018.

Ginsburg is the oldest sitting U.S. Supreme Court Justice and said it is her 'dream' to be on the Supreme Court for as long as former Justice John Paul Stevens, who served for 35 years. Ginsburg has served for 26 years so far.

On Thursday, Ginsburg was seen exiting an SUV wearing a black shawl over a polka-dotted shirt and white trousers that were paired with matching white mules.

She completed the look with black teardrop earrings.

One U.S. Marshal helped her up the steps while another carried her purple backpack.

After her appointment, she was dropped off at a private residence on the Upper East Side.

In an official statement, the U.S. Supreme Court said: 'Justice Ruth Bader Ginsburg today completed a three-week course of stereotactic ablative radiation therapy at Memorial Sloan Kettering Cancer Center in New York City.

'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.'

Last month Ginsburg dismissed concerns regarding her health in an interview with NPR, sneering at a late senator who claimed she would be dead soon after her pancreatic cancer diagnosis in 2009.

'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 recalled.

'That senator, whose name I have forgotten, is now himself dead,' Ginsburg and the interviewer laughed, 'and I am very much alive.'

Pancreatic cancer is one of the most deadly cancers, and only has a 20 percent survival rate in the first year after diagnosis and 7 percent five-year survival rate.

Although Ginsburg could not remember the name of the senator that wished her dead, it appears she is talking about the former Senator to Kentucky Jim Bunning.

In February of 2009, the same year Ginsburg was diagnosed with pancreatic cancer, Bunning suggested during the Republican Party Lincoln Day Dinner in Kentucky that Ginsburg would be replaced soon.

He said Ginsburg had 'bad cancer. The kind you don't get better from.'

'Even though she was operated on, usually, nine months is the longest that anybody would live,' Bunning said at the time.

The Lincoln Day Dinner was on a Saturday, and Ginsburg was back at work that Monday.

In 2017, seven years after retiring from the Senate, Bunning suffered a stroke and died at the age of 85 – one year younger than Ginsburg is now.

Ginsburg told NPR that every time she's had cancer, it was her work on the Supreme Court that 'saved' her

When diagnosed with lung cancer last year, and undergoing surgery to remove the cancerous tumors, there were rumors that President Donald Trump could receive his third opportunity to influence the makeup of the Supreme Court

When diagnosed with lung cancer last year, and undergoing surgery to remove the cancerous tumors, there were rumors that President Donald Trump could receive his third opportunity to influence the makeup of the Supreme Court.

Right when taking office he nominated Neil Gorsuch to take the late Justice Antonin Scalia's seat, and in 2018 nominated Bret Kavanaugh after then-Justice Anthony Kennedy announced he was retiring from the high court.

Ginsburg told NPR that every time she's had cancer, it was her work on the Supreme Court that 'saved' her.

'I had to concentrate on reading the briefs, doing a draft of an opinion, and I knew it had to get done,' she said. 'So I had to get past whatever my aches and pains were just to do the job.'
