Dog can sniff out Lung Cancer
You might heard about a study that dog can sniffs out prostate cancer, now a new study in Germany suggest that dogs can also sniffs out human lung cancer.
According to the study, dogs were able to accurately sniff out tumors in 71% of patients in a German hospital , making scientists hopeful that dogs with their keen sense of smell could be used in early detection of lung cancer.
After smelling the breath of over 200 volunteers including healthy people, lung cancer patients, and patients with chronic obstructive pulmonary disease (COPD), the dogs were incredibly detect lung cancer even in the presence of other scents like tobacco smoke. Current lab tests for lung cancer can’t do this. This suggests that there is indeed a VOC associated directly with lung cancer, which can be detected — at least by a dog — even in the presence of other compounds.
Though the study shows that there is a marker for lung cancer in the breath , still they don't know what it is. There's still more work to be done.
