It may sound unlikely, but a canine may one day save your life.
In a new study, a rescue dog who was trained to detect thyroid cancer by smell was able to do so with nearly the same degree of accuracy as surgically invasive means of testing. Frankie is the first dog to be used in this potentially lifesaving way, but based on his proven ability, he likely won't be the last.
When presented with urine samples from 34 patients, the German shepherd mix was able to correctly determine the benign or malignant thyroid status in 30 of them - an accuracy rate of 88.2 percent - simply by using his nose. The discovery could not only make diagnosing quicker and cheaper, researchers say, but it could also reduce the number of people going under the scalpel by error.
