If Dogs Can Smell Cancer, Why Don't They Screen People? (scientificamerican.com)

An anonymous reader shares an excerpt from a Scientific American report: Dogs can be trained to be cancer-sniffing wizards, using their sensitive noses to detect cancerous fumes wafting from diseased cells. This sniffing is noninvasive and could help diagnose countless people, which begs the question: If these pups are so olfactorily astute, why aren't they screening people for cancer right now? Here's the short answer: Dogs do well in engaging situations, such as helping law enforcement track scents or guiding search-and-rescue teams in disaster areas. But sniffing thousands of samples in which only a handful may be cancerous is challenging work with little positive reinforcement. Moreover, it takes time and energy to train these pups, who, despite extensive preparation, still might miss a diagnosis if they're having a bad day, experts told Live Science.

    It raises the question. It does not beg the question.

    If dogs are cancer-smelling machines, then every single dog in my local dog park must have cancer of the ass.
