We know that dogs have a very acute sense of smell. Our canine companions have long been helping us sniff out things like drugs and bombs. But now they're helping us detect cancer. So your dog could save your life.
Source: @NationalGeographicMedical Detection Dogs is a UK-based charity which trains specialist dogs to detect cancerous cells. There are currently eight dogs who have been trained to detect cancerous cells in people's urine samples.One of them is called Lucy, a cross between a Labrador retriever and an Irish water spaniel, she has been able to detect cancer correctly more than 95% of the time. That's better than some lab tests used to diagnose cancer.
Dogs' noses have 300 million sensors, which is inordinately more than a human's 5 million.They alsohave a second smelling device in the backs of their noses that we don't have. And it's thatdouble smelling system which allows trained dogs to detect cancer's unique odours, called volatile organic compounds.
