Trained dogs and an AI reader prescreen breath for 20 cancers
Bengaluru startup Dognosis trains dogs to detect the volatile organic compounds that cancers push into a person's breath, and uses sensors plus an AI model to translate the dogs' movement, respiration and body language into standardized results instead of a handler's read. In its published Phase 2 study, seven trained dogs identified more than 90% of cancers and more than 91% of non-cancer samples across seven cancer groups covering 20+ cancer types, with similar performance on early-stage disease. A Phase 3 trial started in April across 10 Indian hospitals, aiming to enroll roughly 10,000 people; the long-term plan is about 30 dogs supporting up to a million tests a year. It is a prescreening tool, not a diagnosis.
