Study Shows Dogs Can Sniff Out Lung Cancer

cylonlover writes "Last year, researchers developed a cancer-detecting electronic nose inspired by dogs' ability to sniff out different types of ovarian cancer. Now a new study has found that sniffer dogs' abilities extend to reliably detecting lung cancer. The researchers say the results of the study (abstract) confirm that there is a stable marker for lung cancer, which offers the possibility that a 'breath test' for the early detection of lung cancer could be developed."
