Pets Keep Us Healthy

Man's real best friend may be his best friend's nose. Dogs' sense of smell is incredibly powerful, but it wasn't until recently that scientists began siccing that sense on cancerous tumors. Researchers wondered if canines could be trained to smell the chemical difference between patients with cancer and those without. So far, according to the articles that I read, the results have been promising. Studies show test dogs can accurately pick out patients with lung, breast, ovarian and bladder cancers. In some cases, the pups have hit accuracy rates as high as 97 percent. It's like a K9 dog, it keeps us safe because they can detect bombs if there are bombs.
