Can Dogs Really Sniff Out Cancer? A New Study Says Yes

Over the weekend, a team of Italian scientists made an incredible-sounding claim that could be very exciting if it turns out to be legit: Trained dogs may be able to accurately detect prostate cancer by sniffing urine samples.

A team at Humanitas Research Hospital in Milan used two trained dogs to test 677 urine samples: 320 from men with prostate cancer, and 357 without. On Sunday, the team reported to the annual meeting of the American Urological Association that between the two dogs, there was a 98% accuracy rate. The misses were entirely false positives.
