Marly Garnreiter, 27, from Paris, had been suffering from grief and stress following the death of her father which she believed was the cause of her night sweats and itchy skin
A woman who thought she was suffering from anxiety has told how it was ChatGPT that diagnosed her with blood cancer.
Marly Garnreiter, 27, was suffering from night sweats and itchy skin which she put down to the upset of losing her dad Victor, 58, to colon cancer. She was also losing weight and put her symptoms into ChatGPT which said she likely had blood cancer, but being “sceptical” she ignored it.
Eventually she went to see her GP as she was also feeling tired all the time and getting a pressure in her chest, and a scan revealed she had a mass on her left lung.
She was referred to a pulmonologist who did a biopsy which diagnosed Marly with Hodgkin’s lymphoma – a type of blood cancer. Now Marly has started chemotherapy – which she will receive four to six rounds of – and is taking it all “step by step”.

Marly, a strategist, from Paris, France, said: “I started to lose a lot of weight when he’d just passed away. I kept eating normal amounts of food but I thought it must be the anxiety making me lost a lot of weight. I’d accepted you lose weight with grief.
“I was having night sweats and itchy skin. Again I thought it was anxiety.” Marly lost her dad in January 2024 – after he was diagnosed with colon cancer in 2022.
Her symptoms began shortly after and she saw a doctor for some blood tests but they all came back fine. Her doctor agreed that it was the grief giving her these symptoms.
But as time passed Marly began to question if there was something more to it. She said: “I felt I was processing the grief well. I thought it must be something. In May I sent a took a video to my friends – I had asked ChatGPT and it said I had blood cancer.
“I ignored it. We were all sceptical and told to only consult real doctors.” But in January, 2025, Marly went back to see her doctor. She said: “Around Christmas time I started to feel something was wrong. I had a constant pain in my chest. I was tired all the time.”
Her GP discovered a “big mass” on her left lung and referred her to a pulmonologist. They took a biopsy and Marly was diagnosed with cancer on February 10, 2025. She said: “I felt a lot of anger. I felt like everything was unfair. I didn’t want my family to go through this one more time.”
Marly had a chance to do an egg retrieval so she could freeze her eggs before starting chemotherapy on March 1. She will have four to six cycles. Marly said: “I’m feeling confident for the future.
“It’s really important to listen to our bodies. Sometimes we tend to lose our connection with our inner self. It’s important to be in tune.”
