Former Bachelorette star Katie Thurston has shared an emotional and deeply personal update about her ongoing battle with stage 4 breast cancer — and her words have fans around the world rallying behind her.
The 33-year-old reality TV personality, who rose to fame on Season 17 of The Bachelorette, revealed that she’s been experiencing unexpected and challenging side effects from her treatment, including memory loss and severe hair loss. Thurston, known for her outspoken and confident demeanor, says these changes have been both physically draining and emotionally humbling.

“I’m Losing My Memory”
In a candid Instagram post earlier this week, Katie admitted that she’s noticed troubling lapses in her memory — something she never expected to deal with at this stage of her life. “I’ll be talking and suddenly… I just forget mid-sentence what I was saying,” she explained.
She also appeared on Good Morning America, where she described her symptoms in more detail. “It’s scary,” she said, “but I’m trying to live my best life as a f—king cancer patient.”
A Crucial Medical Milestone Ahead
Katie is now preparing for an important medical update — a July 7 scan to check on the status of her tumors. This moment has been months in the making, and it’s one that both she and her supporters are anxiously awaiting.
In a previous update, she shared that her tumors have been shrinking, a sign that her current treatment plan is making a difference. “I am so relieved,” she posted at the time, adding that the fight isn’t over but progress is being made.

The Toll of Treatment
Like many cancer patients, Thurston has faced a barrage of side effects. She revealed that her treatment has put her into medically induced menopause, triggering hot flashes, dehydration, and exhaustion.
Despite these challenges, Katie maintains a sense of humor and perspective. “I never thought I’d be dealing with menopause before I turned 35,” she joked in a recent post, before turning serious: “But if it helps me live longer, I’ll take it.”
Leaning on Love and Support
Throughout her journey, Katie has leaned heavily on her husband, comedian Jeff Arcuri, who she says has been her “rock” during the most difficult days. The couple married in a private ceremony before her diagnosis, and Arcuri has been by her side at every treatment, doctor’s appointment, and sleepless night.
“Katie is one of the strongest people I know,” Arcuri shared in a recent podcast interview. “She’s teaching me — and everyone around her — what resilience really looks like.”
Finding Strength in Vulnerability
Thurston’s openness has struck a chord with fans. Social media is flooded with messages of encouragement, personal cancer survival stories, and heartfelt thanks from those inspired by her transparency.
“I want people to know it’s okay to talk about the hard stuff,” she said in a live stream. “Even if it’s scary. Even if you feel like you’re falling apart. You’re not alone.”
Looking Ahead
As she awaits her upcoming scan, Katie remains cautiously optimistic. She’s continuing her treatments, focusing on self-care, and keeping her followers updated every step of the way.
“I don’t know what the results will be,” she said, “but I know I’m giving this fight everything I have.”
For now, fans are rallying behind her, sending prayers, good vibes, and love as she faces this next chapter in her cancer battle.
