‘Nervous’ Katie Thurston breaks down in tears as she starts feeling sick amid stage 4 breast cancer battle

Katie Thurston, former “Bachelorette” lead, emotionally shared on Instagram her fear of having COVID-19 amid stage 4 breast cancer treatment, but tests confirmed it was negative, underscoring the anxiety of her condition. On August 30, 2025, Thurston posted Instagram Stories expressing exhaustion and concern during her medication break week, leading her to order a COVID test due to heightened health anxieties. She became tearful, explaining how cancer causes constant worry about infections like COVID, especially with low white blood cell counts, and described feeling like she was “crashing out.” Later, she updated that the test was negative, and she had comforted herself with ice cream, lightening the mood by calling herself a “tired hypochondriac.” Thurston’s cancer journey began with a diagnosis in February 2025, which progressed to stage 4 after spreading to her liver, prompting a treatment plan involving hormone therapy without chemotherapy. She has been open about side effects such as hair loss, memory loss, and medically induced menopause, sharing these updates to raise awareness and support others. In March, she married comedian Jeff Arcuri shortly before starting treatment, adding a personal milestone to her challenging year. Her transparency includes reposting quotes about the emotional toll, like comparing cancer to a “haunted house,” highlighting the ongoing struggle with uncertainty. Despite the hardships, Thurston remains resilient, using her platform to advocate for cancer awareness and provide a candid look at metastatic disease.
