ChatGPT Flags Woman's Symptoms As Blood Cancer A Year Before Formal Diagnosis
Last Updated:
Marley Garnreiter, 27, from Paris, found early signs of Hodgkin lymphoma via ChatGPT months before diagnosis. This instance showcase AI's potential in healthcare
While AI tools like ChatGPT are not designed to diagnose illnesses, there have been increasing instances where they have helped users identify early signs of serious health conditions.
A 27-year-old woman from Paris has shared her extraordinary experience of how ChatGPT identified symptoms of blood cancer almost a year before she received a formal diagnosis from medical professionals. The case has sparked renewed discussion around the growing potential of artificial intelligence in healthcare.
Marley Garnreiter began experiencing night sweats and skin irritation, symptoms she attributed to stress following the loss of her father to colon cancer. Despite multiple visits to doctors, all her test results returned as normal, and no serious health concerns were flagged at the time.
Turning To AI For Clarity
Still concerned, Garnreiter decided to input her symptoms into ChatGPT in search of alternative insights. The AI tool flagged the possibility of blood cancer, a warning she initially dismissed. Speaking to People.com, she admitted she didn't take the suggestion seriously, with friends also advising her not to rely on a machine for health guidance.
Symptoms Persist, Diagnosis Confirmed
Months later, Garnreiter began experiencing chronic fatigue and chest pain, prompting further medical investigation. A scan eventually revealed a large lump in her left lung, leading to a diagnosis of Hodgkin lymphoma, a rare type of blood cancer affecting white blood cells. She is now preparing to begin chemotherapy.
Reflecting on the experience, Garnreiter expressed her shock. 'It's incredible that an AI tool picked up on something so important, well before the healthcare system did.", she said.
While Hodgkin lymphoma is rare, early detection greatly improves treatment outcomes. Medical experts note that the five-year survival rate exceeds 80 percent when identified early. Common symptoms include itching, fatigue, night sweats, fever, and stomach discomfort—many of which Garnreiter had reported.
Although ChatGPT is not a substitute for professional medical advice, her case adds to the growing conversation around AI's potential in symptom analysis, particularly when traditional methods fall short or diagnosis is delayed. However, experts caution that such tools should be used as a supplement rather than a substitute for professional healthcare.

Man shares how he lost 40 kg and built defined abs in 8 months: ‘Walking is literally a fat-loss cheat code'
Transforming your body takes more than just willpower, it requires a clear plan, dedication, and consistency. A man named Rohan Sethi transformed his body in just 8 months, dropping from 114 kg to 74 kg and building defined abs. In his June 25 Instagram post, he shared exactly what he did to achieve this incredible weight loss transformation. (Also read: Woman drops 5 kg in a month with ChatGPT's diet plan: Here's the exact prompt she used for her weight loss journey ) Check out how Rohan Sethi transformed his body from 114 kg to 74 kg in 8 months. (Instagram/@rohreborn) Let's take a look at his diet and workout plan: 1. Eating clean isn't enough Rohan explains that for a long time, he believed eating "healthy" was enough. But despite sticking to foods like oats and grilled chicken, his weight wouldn't budge. "You can eat all the grilled chicken and oats you want, but if you're not in a calorie deficit, you're not losing fat," says Rohan. "I was eating 'healthy'… but eating too much. Once I started tracking my intake, the fat finally came off." 2. Lift weights and stay consistent According to Rohan, lifting weights five times a week made all the difference. Cardio helped with fat loss, but resistance training helped him build muscle and avoid the "deflated" look. "Muscle is what gives your body shape. Without it, I would've looked soft and deflated," he shares. "I trained 5x a week. Nothing extreme. Just consistent effort." 3. Walk a lot Rohan didn't have time for multiple intense workouts a day. Instead, he committed to walking more than 10,000 steps daily and it worked. "Didn't have time for two workouts a day. But I did make time for steps, 10k+ every day," he writes. "It burned calories without killing recovery and kept my hunger in check. Walking is literally a fat loss cheat code." 4. Don't wait for motivation, build structure Rohan points out that he didn't rely on motivation to keep going. Instead, he built systems that made sticking to his goals easier, even on tough days. "Motivation fades. Systems stay," he says. "I planned my food. Trained even when I didn't feel like it. I didn't wait to 'feel ready', I moved anyway." 5. Don't fear the scale Rather than panicking during weight plateaus, Rohan made small, smart changes, like improving his sleep and adjusting his calories. "Weight stalled? I didn't panic," he notes. "I moved more. Slept better. Adjusted calories. Fat loss isn't linear. You plateau. But you push through. That's where most people quit. I didn't." 6. Track progress, even when it's uncomfortable Instead of obsessing over the mirror, Rohan relied on progress videos to keep himself motivated and see how far he'd come. "Progress videos > mirror selfies," he says. "Because when you're about to quit, watching week 1 clips reminds you: You are changing. And it's all worth it." Today, Rohan says he feels stronger, leaner, and more confident than ever. "Face fat gone. Confidence up. Shirt off, no more hiding," he says. "Not magic. Not luck. Just systems, patience, and not giving up when it got tough." Note to readers: This article is for informational purposes only and not a substitute for professional medical advice.

Apollo Cancer Centres launches ‘CanWin' to support patients, survivors, and caregivers
Apollo Cancer Centres (ACC) has launched CanWin, a cancer support group designed to provide structured emotional and psychological support to patients, survivors, caregivers and healthcare professionals. Unveiled during National Cancer Survivors Month, the initiative aims to complement clinical treatment with survivor-led guidance, therapy-based storytelling and open dialogue. The launch event began with survivors sharing their personal narratives of treatment, recovery and coping. A 10-year-old Medulloblastoma survivor from Chennai shared his experience, starting with how a routine check-up led to answers for many of his symptoms. A Hodgkin lymphoma survivor spoke about her delayed diagnosis and complex treatment journey. 'Just months after giving birth, I discovered a lump — first mistaken for tuberculosis. What followed were relapses, five lines of chemotherapy, a bone marrow transplant and 35 rounds of radiation. I missed my child's early years, but I came through with the support of my family and medical team,' she said. Priyanka Bagdi, a leukemia survivor, doctor and author of a book about her experience, spoke about her prolonged hospital stays and the emotional toll of treatment. Experts at the event stressed that while clinical outcomes are improving with advanced diagnostics and early detection, stigma around cancer screening and diagnosis remains a significant barrier. In a panel discussion that followed they called for urgent efforts to normalise conversations around diagnostic tools and to strengthen psychosocial support within cancer care. The programme will continue through monthly support group meetings, survivor-led workshops, expert sessions and volunteering opportunities.

Woman dies of cancer at 23 despite 80% survival chance; her brothers are now blaming mom's anti-medicine theories for it
Kate Shemirani's daughter, Paloma, was diagnosed with non-Hodgkin lymphoma, a type of cancer. Despite doctors informing her that she had an 80 percent chance of survival with chemotherapy, Paloma refused treatment and instead opted for alternative therapies, reportedly under her mother's influence. She died in July 2024 at the age of 23. Also read | World Cancer Day 2025: Cancer spreads from person to person? Here are 4 most common myths and facts about the disease Kate Shemirani's daughter Paloma was diagnosed with cancer. Paloma's brothers blame their mother's anti-medicine conspiracy theories for her death. (Pic courtesy: In a June 23 interview with BBC Panorama, Paloma's brothers, Gabriel and Sebastian Shemirani, blamed their mother Kate's anti-medicine conspiracy theories for her death. They said that Kate's influence led Paloma to reject chemotherapy and medical treatment. Kate Shemirani is a former nurse whose registration was cancelled reportedly due to promoting misinformation about Covid-19. Kate styles herself as 'the Natural Nurse' on social media and has 'been known to spread conspiracy theories and once-fringe anti-medicine views to millions' – which her sons believe contributed to Paloma's decision to refuse cancer treatment. Paloma's elder brother Sebastian said: 'My sister has passed away as a direct consequence of my mum's actions and beliefs and I don't want anyone else to go through the same pain or loss that I have.' 'I wasn't able to stop my sister from dying' The brothers alleged that their mother texted Paloma's boyfriend, Ander, saying, "TELL PALOMA NOT TO SIGN [OR] VERBALLY CONSENT TO CHEMO OR ANY TREATMENT". The brothers further said they hope they can help prevent other deaths like Paloma's, and they believe social media companies should take stronger action against medical misinformation. 'I wasn't able to stop my sister from dying. But it would mean the world to me if I could make it that she wasn't just another in a long line of people that die in this way,' Gabriel said. According to her sons, Kate's anti-medicine views were accelerated in 2012, when she was diagnosed with breast cancer. Even though she had the tumour removed through surgery, she credited alternative therapies for her recovery and reportedly shared online how she used a programme including juices and coffee enemas to become 'cancer-free'. Kate Shemirani's response to son's claims Kate has not directly responded to the allegations made against her by her sons in connection with Paloma's death, but has publicly blamed the NHS (National Health Service) for her daughter's death. She and her ex-husband, Faramarz Shemirani, reportedly said they have evidence that Paloma died due to medical interventions without a confirmed diagnosis or lawful consent. However, the BBC reported it had seen no evidence to support these claims. Paloma's death highlights that it's essential to rely on credible sources and consult with healthcare professionals for accurate information about cancer.
