Dogs who can detect cancer


March 30 th, 2015

Several studies have shown that a well-trained dog is able to detect tumours with surprising accuracy. Through a sense smell at least ten times more powerful than that of humans, and excellent olfactory memory, dogs proved capable of detecting different kinds of tumours. "Cancer generates volatile odorous molecules that enter the bloodstream and is eliminated in the urine, sweat or exhaled air," according Olivier Cussenot, an urologist at Tenon Hospital in Paris. It is a phenomenon that researchers hope one day to take advantage of to develop a safe and non-invasive procedure for diagnosing cancer.
