Beloved NY1 news anchor Ruschell Boone announced on Thursday that her battle with cancer has taken a turn for the worse after her brave return to the air following treatment for pancreatic cancer.

“I’m very touched by all who reached out to see how I’m doing. Unfortunately, my cancer has metastasized in my liver and I’m back in treatment. It’s rough, but the chemo is working,” Boone, 47, tweeted.

“Prayers have carried me through the difficult moments. Thank u for rooting for me.”

The Post reached out to Boone for comment.

The cable channel said there is no timetable for her return.

 “Ruschell is a beloved member of our team. Her first priority is her health, as it should be, so she is taking time off as needed,” a NY1 spokesperson told The Post.

Boone had returned to the anchor chair for the Charter Communications-owned network in March following a nine-month battle with pancreatic cancer.

Upon her return, Boone shared that chemotherapy was “so brutal,” but told viewers of her noon newscast that she was “feeling great.”

Her first interview back on NY1 was with New York City Mayor Eric Adams, when he tweeted saying that “our city is so lucky to have @RuschellBoone back where she belongs — behind the anchor desk and holding all of us in positions of power to account.”

Last year, Boone recalled to The Post how a nagging, vague stomach discomfort she was experiencing in early 2021 evolved into horrible pains that kept her up at night.

In June of 2022, she asked her husband, Todd — a production technician at NY1 — to take her to the emergency room, where a CT scan revealed the devastating news that Boone had pancreatic cancer.

“I just started wailing, crying and looking at my husband, thinking I heard it incorrectly,” she recalled. “I thought, ‘Oh my god, I’m dead’ … My kids [Jackson, 11 and Carter, 9] are going to grow up without a mother.”

Pancreatic cancer is an especially difficult and has led to the deaths of Apple founder Steve Jobs, “Jeopardy!” host Alex Trebek and actor Patrick Swayze.

Five-year survival rates are lower than 10%, according to the National Cancer Institute.

The cancer typically only becomes symptomatic after it’s spread to other organs, at which point it can be treated with very limited success.

Miraculously, Boone’s was caught early, which gave her a fighting chance.

Since her diagnosis, the newswoman has become an advocate in the battle against pancreatic cancer.

She recently posted on Instagram sharing that she was emceeing and participating in the Pancreatic Cancer Action Network’s Purple Stride walk to end pancreatic cancer, which happened in April.

An earlier post shows that she also attended Memorial Sloan Kettering’s Comedy vs Cancer fundraiser event.
