Breath-Sniffing Dog Sparks AI Nose for Early Cancer Detection
A German shepherd named Inca obsessively sniffed her owner Colleen Ferguson’s breath, leading to a CT scan that found a golf-ball-sized lung tumor at stage 1 and a successful surgical removal with no further treatment. The story adds to evidence that dogs can detect cancer by scent, and researchers are developing an MIT‑based AI-powered “e-nose” to mimic canine olfaction for noninvasive cancer detection, currently being tested on urine samples with the goal of clinical use within two years and potential smartphone integration.
