A California clinic is training Labrador Retrievers to sniff  and detect lung cancer in humans in the same manner that is used to train drug sniffing dogs.

  The canine were presented with breath samples of cancer patients and of robust people that was secreted in plastic containers if the dog smelled cancer it sat down and received a treat.

  The canines have a 99 percent accurancy and could  some day be used to warn its owner about cancers insidious incipientness.
