Four family dogs – two German shepherds, one Australian shepherd and one Labrador retriever – smelled test tubes containing breath samples of 220 patients, both those with lung cancer and those without it.

According to the study, the dogs successfully identified lung cancer in 71 out of 100 patients with the disease. CNN
