Are Dogs Able to Sniff Out Lung Cancer?

A new study finds that dogs specially trained to sniff for lung cancer may have more work to do.

The dogs sniffed the breath samples of 122 people and correctly identified the subjects with lung cancer 78.6 percent of the time. However, they were only able to detect 34 percent of patients who do not have lung cancer.

“Our dogs made mistakes with both positive and negative samples," said study co-author Klaus Hackner, from Krems University Hospital in Austria. Hackner thinks the dogs’ success rate could be improved in a training program designed to reward them more often. The study was published in the Journal of Breath Research. — Read it at Seeker
