In a heartbreaking update that shook Bachelor Nation, Katie Thurston has confirmed her breast cancer has advanced to stage 4. The former Bachelorette star took to Instagram to reveal that the cancer, originally found in her breast, has now spread to her liver.
“Unfortunately, after three days of waiting, I did find out today that my breast cancer has spread to the liver,” Katie shared with her followers. “It is fairly small, however, that does put me at stage four.”
Katie first announced her diagnosis on February 15. At the time, she was still undergoing testing and preparing to begin treatment. But a suspicious spot found on her liver during a PET scan changed everything. After a biopsy, the news was confirmed. In a somber but composed message to her subscribers, she wrote just two words: “Stage 4.”
Treatment Delayed, But Not Her Spirit: Katie Remains “Optimistic” About the Outcome
Despite the severity of the diagnosis, Katie is holding strong. She explained that while the cancer has spread, the spot on her liver is small and was caught early-two things working in her favor.
“I know stage four can sound very scary, and it can be,” she admitted. “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.”
Katie will begin chemotherapy next Friday. She started her treatment in California. Now, she has moved to New York and transferred her care to Columbia University Medical Center. That’s where doctors performed the PET scan that ultimately revealed the liver spot. She added, “I’m very confident in the team at Columbia, and I just wanted to share that update.”
The move delayed her treatment, but also saved her life. In her own words, she explained, “They never did a PET scan in California. It wasn’t part of the initial testing.” That test was the one that revealed the advanced stage.
