Dogs can sniff out cancer with nearly 97% accuracy, says study
For the study, the researchers used a behavioral technique called “clicker training” to teach four beagles to differentiate between healthy blood samples and ones taken from people with malignant lung cancer.
One of the dogs, Snuggles, was “unmotivated to perform,” according to a press release. But the other three averaged a 96.7 percent accuracy at identifying the lung cancer samples and 97.5 percent accuracy at spotting the healthy samples.
According to researcher Heather Junqueira, the team sees two ways scientists could harness this puppy power to detect cancer.
“One is using canine scent detection as a screening method for cancers,” she said in the press release, “and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds.” ■
