The Newest Way to Detect Cancer? Let Fido Sniff it Out - - TIME Healthland: German researchers report in the European Respiratory Journal that dogs can be trained to detect lung cancer by sniffing human breath. The scientists worked with an admittedly small number of canines — just four, including two German shepherds, a Lab and an Australian shepherd — but the dogs had good success. They were able to suss out cancer in 71 out of 100 breath samples from lung cancer patients, and were able to correctly identify 93% of cancer-free samples, giving them an impressively low rate of false positives.
