Dogs Sniff out Cancer

Can dogs detect cancer? There have been numerous popular science stories doing the rounds over the last two years and anecdotal evidence is mounting. But, in a world where lung and breast cancers are among the leading causes of cancer death, it seems that any early detection method is highly desirable, however canine it might be.

Now, a study published in the March 2006 issue of the journal Integrative Cancer Therapies presents astonishing evidence that man’s best friend, the dog, may indeed be able to sniff out cancer.

Apparently, the dog’s extraordinary sense of smell can distinguish between healthy people and those with both early and late stage lung and breast cancers from healthy controls.
