(Newser) – Dogs are lung cancer detection experts, a study finds. They "have no problem identifying tumor patients," says a researcher in Austria, and that could lead to earlier diagnoses. Dogs who smelled 120 breath samples were able to sniff out cancer 70% of the time, a very "encouraging" result, says the scientist. It confirms anecdotal accounts of dogs behaving differently near people with cancer, AFP notes. But don't expect your next doctor to be named Rover: Scientists hope they can figure out what scents the dogs are picking up and make an "electronic nose" that mimics the canine one.
