Bachelorette star Katie Thurston has shared a heartbreaking update about her Stage 4 breast cancer diagnosis.

She posted an Instagram Reel detailing her daily struggles living with the gruesome disease.

The 34-year-old had no family history of cancer when she was diagnosed on February 13 after discovering a painful lump in her breast.

In her latest video, she got emotional as she spoke about the devastating symptoms she has endured, which included memory and hair loss.

‘I wanted to do weekly check-ins that are just like uncut, raw emotions of like whatever comes to my mind,’ she detailed in the Reel on June 1 – National Cancer Survivors Day.

In March, just one week after her wedding to comedian Jeff Arcuri, 36, Katie revealed that the cancer had spread to her liver, taking her from Stage 3 to Stage 4.

During her new Reel, the former Bachelorette revealed she had just finished her second month of treatment.

‘If you’re asking how long treatment is, technically forever. I am optimistic about medical advancements in the future. Fingers crossed as a Stage 4 girly,’ she shared.

Katie, who wore a pink New York Yankees hat during the video, added: ‘My hair is coming out in an unnatural amount of clumps. Working on that.’

She also said her treatments have been causing her to ‘lose her memory.’

Katie detailed that she was going through customs after a recent vacation with her husband and struggled to remember where they had visited.

‘[They asked], “Where are you coming from?” And I looked at them and I was like, “I don’t remember. I don’t remember,”‘ she recalled with tears in her eyes.

‘Jeff and I got in a, not an argument, but you know, a little disagreement. I was like, “This has happened before,” and he’s like, ‘”When?” I was like, “I don’t know, but I know it has.”‘

She added: ‘We’re able to laugh about it now. But yeah cancer is s**t.’

‘Sometimes I’m like, “Stop feeling bad for yourself,” but then other times I’m like, “No, you’re allowed to feel bad for yourself. Cancer f**king sucks,”’ she said.

‘Right now I’m at the process of my treatment where I have to make big decisions on how to treat my liver.’

Katie revealed that she had decided on histotripsy to treat her liver, which uses ultrasound waves to treat tumors.

She added: ‘Every day I’m alive, I’m a survivor. So go me, I guess.’

The Bachelorette also shared that the treatment that was supposed to put her into medically-induced menopause didn’t work.

‘Got my period, that’s not supposed to happen,’ she explained.

She explained that she is switching medication, but if that doesn’t work, ‘I might have to get my ovaries taken out. Not ideal.’

Katie concluded: ‘The vacation was nice. Now I’m back at it, again, in New York City, trying to live my best life as a f**king cancer patient.’

‘Sorry – I’m not gonna edit that out,’ she said about swearing, which she bleeped out, ‘I want this just to be my truth.’

Katie was a bank marketing manager when she first competed for the heart of Bachelor #25 Matt James in 2021.

She scored her Bachelorette spin-off where she romanced fiancé Blake Moynes for six months and John Hersey for seven months.
