NEW YORK — Former “Bachelorette” Katie Thurston says she has stage IV breast cancer, but is optimistic as she begins treatment. 

She posted a social media video Friday, running through the last month and a half of her life since first being diagnosed with breast cancer. 

“I had to go through several more tests, including a CT scan, cone density scan, blood work, MRI,” she said, going on to mention having a PET scan which can “sometimes it can detect things that some of the other tests did not.”

Wearing a sweater and having bandages over her collarbone and chest, Thurston continued to explain she is officially starting treatment next week. 

“Unfortunately it did detect some spots on my liver, that were a little suspicious,” she said. 

After more tests and biopsies, Thurston says they confirmed her breast cancer spread to her liver. 

“It is fairly small. However, that does put me at stage IV,” she said. “I know stage IV 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.”

She said the diagnosis came as she was moving from California to New York with her new husband comedian Jeff Arcuri, so she had to transfer medical records over and chose to focus on fertility before beginning cancer treatment. 

The two got married March 22, a month after Thruston announced her cancer diagnosis. 

Thurston, a 34-year-old bank marketing manager, first appeared on Matt James’ season of “The Bachelor” before starring in her own season of “The Bachelorette.” 

In the 17th season of the show, which aired from June until August 2021, Thurston fell for Moynes, a surprise candidate who crashed the show after experiencing rejection from Tayshia Adams in the previous installment of “The Bachelorette.” 

Thurston and Blake Moynes described their relationship as incompatible and called it off a few months after the show aired. 

“We are so grateful for the moments we shared together and the entire journey that has unfolded this year, but we ultimately have concluded that we are not compatible as life partners, and it is the most caring choice for both of us to move forward independently,” they said.
