ChatGPT Helps Solve Medical Mystery After Doctors Misdiagnose Woman's Cancer Symptoms
In February 2024, Lauren Bannon noticed she couldn't bend her little fingers properly. After months of testing, doctors diagnosed her with arthritis.
Lauren Bannon, from Newry, Northern Ireland, was shocked when ChatGPT helped expose a life threatening health issue. In February 2024, Lauren noticed she couldn't bend her little fingers properly, which left her worried. After months of testing, doctors initially diagnosed her with rheumatoid arthritis, even though the test results were negative. Desperate for answers, she shared her symptoms on ChatGPT and the AI service suggested she might have Hashimoto's disease. Although her doctors weren't sure, Lauren was determined to get tested and in September 2024, AI's suggestion was correct. Further scans showed two lumps in her thyroid, which were confirmed as cancer in October.
Speaking with Mirror, she said, 'I felt let down by doctors. 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. So that's when I pulled up ChatGPT. I already used it for work. I started typing what mimics rheumatoid arthritis and it popped up saying 'You may have Hashimoto's disease, ask your doctor to check your thyroid peroxidase antibody (TPO) levels.' So I went to my doctors and she told me 'I couldn't have that, there was no family history of it' but I said 'just amuse me'."
In January 2025, Lauren Bannon had surgery to remove her thyroid and two lymph nodes from her neck. She now has to be checked regularly for the rest of her life to make sure the cancer doesn't come back. She believes that because her symptoms were not the usual signs of Hashimoto's disease, doctors might not have found the real problem in time. She didn't feel tired or weak like others go through. If ChatGPT wasn't there for her help, she would have kept taking medicine for an illness she didn't actually have.
'The doctor said I was very lucky to have caught it so early. I know for sure that cancer would've spread without using ChatGPT. It saved my life. I just knew that something was wrong with me. I would've never discovered this without ChapGPT. All my tests were perfect. I would encourage others to use Chat GPT with their health concerns, act with caution but if it gives you something to look into, ask your doctors to test you. It can't do any harm. I feel lucky to be alive," Lauren added.
Speaking with Fox News, Dr Harvey Castro, an emergency doctor and AI expert from Dallas, said that tools like ChatGPT can be helpful because they make people more aware of their health. He believes AI can support doctors by giving helpful suggestions and information, but it should never replace real medical professionals, as it cannot check a patient, make a final diagnosis or give proper treatment. He feels that if AI is used the right way, it can improve healthcare, but completely relying on it can be risky.

Doctors declared her dead. His family urged him to leave her, but he proved 'true love does not walk away.' Here's how
The doctors had officially declared her dead. But it was her loving husband who insisted that she had not yet left the living and stayed by her for 30 days, bathing and feeding her diligently. In this crisis, Varinder proved he was here to support her in sickness and health, as he had once vowed to when they tied the knot. Life had been gentle and fulfilling for a woman who shared her heartfelt story through Humans of Bombay. Married to Varinder through an arranged setup, she remembered falling in love the moment she saw his photograph. Without any hesitation, she told her father about her feelings, and the two families soon united the couple in marriage. Their routine was simple but fulfilling—daily visits to the temple, leisurely walks holding hands, and raising their two children with love and care. For a long time, life felt perfect—complete in every sense.

That day, as she was descending a flight of stairs, a sudden stumble left one of her legs feeling oddly numb. Believing it to be a sign of tiredness, she initially ignored the sensation. However, Varinder was concerned and took her to consult a doctor. Even the medical expert dismissed it as something minor. But what followed the next morning changed their lives forever. An Unexpected Diagnosis As she attempted to get out of bed the following day, her body gave way—she collapsed and realized she could no longer feel her leg. Alarmed, she screamed for Varinder, who immediately rushed her to the hospital. After a series of tests, doctors diagnosed her with Guillain-Barré Syndrome ( GBS ), a rare but life-threatening neurological disorder. The situation quickly spiraled into a nightmare. Her body became a battleground of pain and paralysis. Needles pierced her skin constantly, and eventually, even the simple act of breathing turned into a struggle. Varinder, helpless but determined, repeatedly pleaded with medical staff to help his ailing wife. But no treatment seemed to work. Then came the worst moment—her consciousness faded, and everything went dark. A Husband's Refusal to Let Go When she regained awareness, she found herself in a different hospital. Varinder explained what had transpired during her blackout. The previous hospital had administered an incorrect dosage of medication, nearly ending her life. The attending doctors had declared her dead, certain there was nothing more they could do. But Varinder, unwilling to accept their finality, took matters into his own hands. For 35 relentless minutes, he performed CPR on her, refusing to surrender to fate. Miraculously, his efforts succeeded — she came back to life. This was not just an act of love; it was a battle for survival that he chose to fight alone when the world had already given up. Standing Strong Amid Pressure and Pain Throughout her hospital stay, Varinder remained a constant presence. Despite immense pressure from relatives and even some medical staff suggesting that he abandon her—saying she would not recover and it was better to send her back to her maternal home—Varinder refused to budge. Every single day, he remained by her side. He bathed her gently each morning, ensured she received every meal on time, and held her hands whenever she underwent painful treatments. His dedication went far beyond duty—it was a living embodiment of the marital vows they had taken years ago. A Caregiver's Journey at Home After an entire month of intensive care, she was finally discharged. But the journey to recovery was far from over. At home, Varinder took on multiple roles—caregiver, father, homemaker, and breadwinner. He looked after the children, managed household chores, and continued his job, all while tending to her every need with compassion and care. To her, it felt like being reborn. Varinder gave her a second life, one that was fragile yet filled with love and meaning. A Testament to Enduring Love Thirteen years have passed since that harrowing ordeal. Though she now walks with a limp and is a bit slower than she used to be, the love between them remains unchanged. In fact, it has only grown deeper. Hand in hand, they still go on walks—just like they used to—a powerful symbol of a love that defied death and despair. In every sense, Varinder lived up to the promise made during their wedding: to be there in sickness and in health. "He gave me a new life. That's the treatment I received—not medicines, but love. He proved that true love doesn't walk away, even when life gets hard.." she wrote. Understanding Guillain-Barré Syndrome (GBS) According to the Mayo Clinic , Guillain-Barré Syndrome is a rare condition where the body's own immune system mistakenly attacks its nerves. The condition often begins with a sensation of tingling or numbness in the hands and feet. This feeling can rapidly worsen, leading to muscle weakness and, in severe cases, full-body paralysis. GBS is considered a medical emergency, and most patients require hospitalization. Though its exact cause remains unknown, in about two-thirds of cases, the onset of GBS is preceded by an infection — such as a respiratory or gastrointestinal illness, and sometimes even COVID-19 or the Zika virus. The progression of symptoms can be swift. Initial indicators may involve: Tingling or a "pins and needles" sensation in fingers, toes, ankles, or wrists. Muscle weakness, beginning in the legs and potentially spreading to the upper body. Difficulty with walking, balance, or climbing stairs. Problems with facial expressions, chewing, or speaking. Double vision or eye movement challenges. Severe nerve pain that may worsen at night. Complications with bladder or bowel control. Irregular heartbeat or unstable blood pressure. Respiratory issues that can become life-threatening. Due to the serious and unpredictable nature of GBS, early detection and immediate medical attention are crucial. Recovery can take weeks to months, and some patients may face long-term effects, including limited mobility. Final Thoughts: Love's Resilience This powerful story is not just about survival; it's about an unbreakable bond. In an age where relationships often falter at the first sign of hardship, Varinder's steadfast commitment stands as a moving testament to what love truly means. He didn't just stand by her in her darkest hour—he pulled her back into life through sheer will and devotion. Their journey offers hope, courage, and a reminder that when love is real, it doesn't run away from storms—it becomes the shelter.

Are AI tools making you forgetful and dull? Here's how to prevent a brain burnout
Dr Prabash Prabhakaran The other day, a 26-year-old software engineer from Bengaluru came to see me because she was worried about something I'm hearing more and more, 'I feel mentally lazy,' she said. She didn't have a memory problem. No headaches either. There were no neurological warning signs. However, something had changed. Once shrewd and confident, she now relied on AI apps and tools for everything, from brainstorming meeting ideas to client emails and code snippets. She became aware over the months that she was losing her ability to remember things. She would repeatedly ask AI the same questions, lose track of technical concepts and forget project details. What was causing her the most distress? She declared, 'I've lost my curiosity. Besides, why think when I can get it done by someone else?' Her situation exemplified cognitive disuse, which is the process by which the brain dulls like a muscle left unworked. The mental cost of continuously outsourcing our ability to think, remember and make decisions is known as cognitive debt. It's like skipping out on exercise; if you don't go to the gym long enough, your muscles will weaken. Similarly, when we stop pushing our brains, they become less resilient. This change takes time to manifest. It's not about getting lost on the way home or forgetting your birthday. It begins subtly: You become distracted without reminders or prompts, lose your train of thought in the middle of a sentence or find it difficult to remember something you used to know by heart. I still recall a specific patient saying, 'I no longer trust my brain.' What causes this dullness? Our brains are made to think deeply, remember things and solve problems. The neural pathways supporting these abilities are strengthened each time they are stretched. The great thing about neuroplasticity is that it gets stronger the more you use it. However, those circuits aren't triggered when AI takes over the mental labour. This can eventually impair mental acuity, concentration and independent thought, particularly in young adults whose brains are still developing. Therefore, the true question is not whether AI causes forgetfulness but rather whether we are utilising it in ways that contradict or replace our own thought processes. The silent burnout Physical exhaustion is not the same as cognitive fatigue. It's a silent feeling of dreariness, like fog. A few indicators are requiring reminders to complete basic tasks, ignoring what you just read, mentally 'flat' even after taking a break or losing interest in critical thinking or problem-solving. Classrooms, workplaces and homes are all experiencing what Riya did. Our active thinking starts to wane as we consume passively. How then does one strengthen one's mind? AI shouldn't replace thought, just as calculators didn't replace math. Instead of being a crutch, it ought to be a tool. The following are a few easy yet effective methods to improve your cognitive fitness: 1. Intentional recall: Before searching, take a moment to try and recall. 2. Active participation: Don't replace your ideas with AI; use it to test them. 3. Mental exercises: Include deep reading, crossword puzzles and logic games. 4. Tech sabbaticals: Unplug frequently to allow your thoughts to roam. Not only do we lose speed when we allow a machine to think for us, we also lose sharpness. Let's remember to think independently in a world full of intelligent tools and instant prompts. The human brain, which was designed to be used, continues to be our most potent processor.
