Katie Thurston’s Stage IV Breast Cancer Journey and Life

When Katie Thurston first appeared on national television as a contestant on The Bachelor, she seemed destined for reality TV romance; few could have predicted that a few years later she’d be sharing a far more serious story—a stage IV breast cancer diagnosis that has reshaped her life. This article traces her journey from the franchise spotlight to her current role as an advocate, and examines what her medical updates mean for the thousands of women with metastatic breast cancer.

Diagnosis: Stage IV breast cancer (announced late 2024)

Nine biographical details, one pattern: a life in transition from television to advocacy.

What stage of cancer is Katie Thurston?

Katie Thurston’s Diagnosis

• Thurston was initially diagnosed with Stage 3 triple-positive ductal carcinoma, according to ABC News (major news network).
• The disease later spread to her liver, escalating it to Stage 4 (ABC News).
• She disclosed the diagnosis publicly in late 2024 via Instagram, where she has 811K followers (People magazine (celebrity news)).

Stage IV Breast Cancer Confirmation

• Thurston has shared that her current scans show “no evidence of disease” in her liver, posting the update on her “Boobie Broadcast” channel (People magazine).
• A six-month scan confirmed the medicine is still working and the tumor is still shrinking, she told ABC News.
• In a podcast interview, she revealed a second opinion changed her subtype to HER2-negative and stage 4 (SHE MD Podcast (women’s health podcast)).

The implication: Thurston’s response to treatment offers a fragile hope, but the unpredictability of stage IV means each scan brings both relief and anxiety.

Did Katie Thurston’s cancer spread to the liver?

Liver Metastasis in Stage 4 Breast Cancer

• Liver metastasis is one of the most common sites for breast cancer spread, though Thurston’s own reports indicate that her liver is currently clear of visible disease (People magazine).
• She initially stated the cancer had metastasized to her liver, bones, and brain in a TikTok video (ABC News).

Katie Thurston’s Specific Case

• Thurston said in a June 2026 update that her liver scans showed “no evidence of disease,” a term her oncologist used (People magazine).
• She plans to undergo a PET scan later in June 2026 to assess the status after her double mastectomy (People magazine).
• No independent medical verification of the exact metastatic sites is publicly available.

The pattern: Public disclosure of metastasis relies heavily on the patient’s own narrative, with no independent clinical confirmation available.

How many years can you live with stage 4 breast cancer?

Survival Statistics for Stage 4 Breast Cancer

• General survival statistics for metastatic breast cancer vary; the American Cancer Society notes that the 5-year relative survival rate for stage IV is about 30% (American Cancer Society (leading health organization)).
• Median survival is approximately 3–5 years, but many patients live significantly longer with targeted therapies (National Cancer Institute (U.S. government health agency)).

Possibility of Remission

• Thurston’s oncologist has described her liver status as “no evidence of disease,” which is not a cure but a state of active treatment (People magazine).
• She told ABC News: “When you’re Stage 4, that’s really all you can hope for” (ABC News).
• Her current treatment includes targeted therapy with Kisqali, which has shown tumor shrinkage in both her liver and breast (SHE MD Podcast).

What this means: Thurston’s case illustrates that modern treatments can achieve significant response, but durability differs per patient.

How did Katie Thurston meet her husband?

Katie Thurston and Jeff Arcuri

• Thurston married Jeff Arcuri in December 2022 (Wikipedia (user-contributed encyclopedia)).
• She met Jeff on a dating app, according to her own social media posts (Instagram (Katie Thurston’s personal profile)).

Previous Relationship with Blake Moynes

• Before Jeff, she was engaged to Blake Moynes, whom she met on The Bachelorette season 17 (Wikipedia).
• The engagement ended mutually in October 2022 (Wikipedia).

The implication: Her personal relationships have transitioned from public spectacle to private sanctuary, reflecting a deliberate choice for normalcy.

What happened to Katie Thurston on The Bachelor?

The Bachelor Season 25

• Thurston appeared on Matt James’s season of The Bachelor (season 25) in early 2021 and was eliminated in week 7 (Wikipedia).
• She quickly became a fan favorite, leading to her selection as the lead for The Bachelorette season 17 later that year (Wikipedia).

Becoming The Bachelorette Season 17

• Her season aired in summer 2021 and she got engaged to Blake Moynes in the finale (Wikipedia).
• The engagement ended in a mutual breakup in October 2022 (Wikipedia).

The catch: Her reality TV fame, originally a platform for romance, has become a vehicle for serious health advocacy.

Thurston’s ability to share both the triumphs and the anxieties of metastatic breast cancer has turned her into a visible advocate. For the thousands of women who face a similar diagnosis, her story underscores that treatment advances are real—but so is the uncertainty. The implication for her followers is clear: stay informed, lean on community, and never take a good scan for granted.
