India startup trains dogs to spot cancer | AI analyses dogs’ reactions to human breath sample
On a farm outside Bengaluru, rescue dogs like Chloe are doing unusual work — sniffing human breath samples for cancer while wearing 3D-printed "doggy Iron Man" helmets packed with sensors. Startup Dognosis pairs the dogs' 300-million-receptor noses with AI that reads their brain activity, respiration, and body language to flag likely cancer cases. In trials across six Karnataka hospitals with 1,500+ participants, the method reportedly topped 90% accuracy across seven cancer types.
