Gov. Phil Murphy is scheduled to have surgery Wednesday to remove a tumor from his kidney – a tumor the governor says that has a 90% chance of being cancerous.

The governor announced his health issue last month. Doctors at an undisclosed New York hospital are preparing to perform the surgery, which will remove the 1.1-inch tumor, along with parts of the 62-year-old Murphy’s left kidney.

Murphy says that his prognosis is good, but that Lt. Gov. Shelia Oliver will take over as acting governor for a few days while he recovers.

“I feel great. We’re going to take care of this, God-willing, tomorrow. I’ll be out of commission, I hope, for only a few days,” Murphy said at his last public event Tuesday morning.

Oliver will be in charge during the surgery and initial recovery. Murphy is expected to remain at the hospital in New York for at least two days. Then, he'll be released and head home on Friday or Saturday.

"You don't take something like this for granted or lightly, but based on all the advice we've gotten, medical advice as well as those who have gone through this before, we enter this with a spirit of optimism and that includes yours truly,” Murphy said.

The governor says that Oliver has been fully informed every step of the way on coronavirus preparedness. Murphy is expected to retake the office as governor when he returns to New Jersey and plans to recover at home for about a week.

Elected officials from across the state have wished the governor well.

"All we can do is give him a few prayers and hope that he gets through this pretty quickly,” says Senate President Steve Sweeney, who has sparred with Murphy in the past over state issues. “What the prognosis says is it's good, but I got to feel for him and his family because it's scary as hell to deal with that."

Murphy says that he does not expect to undergo radiation or chemotherapy treatment. He has said that he is "profoundly grateful" to his doctors for detecting the tumor early.
