A mother of two credits ChatGPT for saving her life, claiming the artificial intelligence chatbot flagged the condition leading to her cancer when doctors missed it.
Lauren Bannon, who divides her time between North Carolina and the U.S. Virgin Islands, first noticed in February 2024 that she was having trouble bending her fingers in the morning and evening, as reported by Kennedy News and Media.
After four months, the 40-year-old was told by doctors that she had rheumatoid arthritis, despite testing negative for the condition.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Desperate to pinpoint the cause of her symptoms, Bannon turned to ChatGPT, the large-language model made by OpenAI.
The chatbot told Bannon that she may have Hashimoto’s disease, an autoimmune condition where the body’s immune system mistakenly attacks the thyroid gland, causing it to become inflamed and eventually underactive, according to Kennedy News and Media.

Despite reservations from her doctor, Bannon insisted on being tested for the condition in September 2024 — and was shocked to discover that ChatGPT was correct, despite the absence of any family history.
This prompted doctors to perform an ultrasound of Lauren’s thyroid, when they discovered two small lumps in her neck that were confirmed as cancer in October 2024.
“I needed to find out what was happening to me, I just felt so desperate. I just wasn’t getting the answers I needed.”
Bannon claims she would never have found the hidden cancer without the help of ChatGPT, which she credits for helping to save her life.
“I felt let down by doctors,” said Bannon, as reported by Kennedy News and Media. “It was almost like they were just trying to give out medication for anything to get you in and out the door.”

“I needed to find out what was happening to me, I just felt so desperate. I just wasn’t getting the answers I needed.”
Bannon said she had been using ChatGPT for work. When she asked the chatbot about which medical conditions mimic rheumatoid arthritis, it answered, ‘You may have Hashimoto’s disease, ask your doctor to check your thyroid peroxidase antibody (TPO) levels.’”

After her cancer diagnosis in January 2025, Bannon underwent an operation to remove her thyroid and two lymph nodes from her neck. She will now remain under lifelong monitoring to ensure that the cancer doesn’t return, according to the report.
Due to not presenting with typical symptoms of Hashimoto’s disease, Bannon believes her condition, and subsequent cancer diagnosis, would have remained undetected without the help of ChatGPT.

“I didn’t have the typical symptoms of Hashimoto’s disease — I wasn’t tired or feeling exhausted,” she said, per Kennedy News and Media.
“If I hadn’t looked on ChatGPT, I would’ve just taken the rheumatoid arthritis medication and the cancer would’ve spread from my neck to everywhere else.”

“It saved my life. I would’ve never discovered this without ChatGPT. All my tests were perfect.”
Bannon encourages others to use the chatbot to investigate their own health concerns, but to “act with caution.”
“If it gives you something to look into, ask your doctors to test you,” she suggested. “It can’t do any harm. I feel lucky to be alive.”

Dr. Harvey Castro, a board-certified emergency medicine physician and national speaker on artificial intelligence based in Dallas, Texas, said he welcomes the role of AI tools like ChatGPT in raising awareness and prompting faster action, but also urges caution.
“AI is not a replacement for human medical expertise,” he told Fox News Digital. “These tools can assist, alert and even comfort — but they can’t diagnose, examine or treat.”

“When used responsibly, AI can enhance healthcare outcomes — but when used in isolation, it can be dangerous,” Castro went on. “We must prioritize patient safety and keep licensed medical professionals at the center of care.”
