Dog trained to detect thyroid cancer 'with 88% accuracy'

Frankie the dog delivers the diagnosis through smelling patients' urine samples, according to a study conducted by the Arkansas University for Medical Sciences.

A group of researchers in Arkansas have trained a dog to detect thyroid cancer by smelling patients' urine samples.

The german shepherd-mix named Frankie predicted with 88% accuracy which patients had thyroid cancer and which had a benign disease. The formerly stray pup was rescued from a busy street in Little Rock, Arkansas.
