And now, one week after saying “I Do”, Katie has revealed that she recently learned her breast cancer has spread to her liver.

Speaking out in a new video shared on Instagram, Katie said: “After days of waiting, unfortunately, I did find out today that my breast cancer has spread to the liver.

“It is fairly small, however it does put me at stage four,” she revealed.

She explained how she will now be starting a “new treatment plan” that will involve chemotherapy.

Katie is due to start her new treatment plan next week.

Speaking candidly in the new video, she said: “I know stage four can sound very scary, and it can be.

“However, given that I am triple positive and the spots on my liver are fairly small and detected early, I feel very optimistic on my outcome.”

In the caption, she penned: “43 days since diagnosis and still no treatment? There is a lot of testing and prep that goes into cancer treatment.

“One important test is checking to see if the cancer has metastasized (spread). Unfortunately for me, mine has and I am now #stage4breastcancer. I’ll finally start my treatment next week.”

SUPPORTED BY HUSBAND JEFF

Her husband, comedian Jeff Arcuri, commented on the video and touchingly penned: “You’re the strongest woman I know. We got this.”

Meanwhile, droves of fans were quick to comment and share their love and support also.

“Stage 4 is not a death sentence. I’m thriving and living as normal as before. You got this,” penned one.

Another added: “Thanks for keeping us updated Katie!! Your strength through all of this is so inspiring. You are in my prayers daily.”

A third person then said: “I’ve been a cancer prevention advocate for years and know plenty of people who beat Stage 4. You got this, Katie.”

Who is Katie Thurston?

Katie is American television personality, best known for her appearances on dating-reality shows in the Bachelor and Bachelorette franchise, as well as the career in comedy she has been carving out.

The 34-year-old star shot to fame on The Bachelor in 2021, but failed to find love.

She then was the leading lady of The Bachelorette that same year.

She was engaged to Blake Moynes during her season of The Bachelorette, but the couple sadly split.

Katie and Blake ended their engagement in October 2021 due to “distance”.

At the time of their split, a source told The U.S. Sun: “Katie flew up to Canada early Saturday just a few hours after the comedy show and saw Blake for the first time in a while.

“I don’t think she flew there necessarily knowing it would be a breakup trip, but she knew they’d be forced to address a lot of things that they had been putting off for a while.”

After adding that “distance was a big factor,” the insider alleged: “Blake wasn’t ready to leave Canada and Katie wasn’t ready to move there.

“She just set down new roots in San Diego and loves it there.”

They continued: “Another big thing they had issues with were their communication styles.

“Katie is much quicker to call little things out whereas Blake just lets things slide.

“Her outbursts eventually became too much for him to handle.”

While a fourth added: “You’re so strong & brave! You’ve got this girl! Thank you for sharing your journey with us and continuing to pray for you.”

And a fifth penned: “Looking forward to you coming out on the other side of this.”

‘SHOW UP OR DIE’

Katie recently spoke on Good Morning America to Eva Pilgrim about her diagnosis.

She said hearing she had breast cancer was “the worst feeling I’ve ever felt.”

“You’re just devastated. It’s so shocking,” she said.

“As a 34-year-old woman, you’re just not prepared.”

“When I felt my lump, it was sore. As women, we’re used to being told, oh, it’s probably your time of the month, or it’s your time of the month. So I just brushed it off for a while.”

She then spoke about treatment, revealing, “Because of the size of the tumor, I have to do chemo first to shrink it down. Then I can have it removed.”

Katie later declared: “You don’t have a choice. You show up or you die.

“I hate to say it that way. Every day you have an appointment, every day you have to show up.”

KATIE’S LOVE STORY

Katie starred as the lead in season 17 of The Bachelorette in 2021.

She previously appeared on season 25 of The Bachelor but didn’t find love.

In June 2024, Katie – who has dabbled in comedy herself – revealed on social media that she was dating comedian Jeff Arcuri.

And last September, they revealed that Jeff had popped the all-important question, with the couple announcing their engagement.

The stunning star is now loved up with her husband Jeff, whom she married on March 22, 2025.

Announcing they had tied the knot on Instagram, Katie shared some sweet snaps from their big day and wrote: “We said ‘I do’ on March twenty two.”
