Dog Sniffs Out Cancer In Human Urine
randomErr writes: University of Arkansas for Medical Sciences found out that a scent-trained dog can identify thyroid cancer in human urine samples 88.2 percent of the time. Frankie, a male German shepherd mix identified the presence of cancerous cells in 30 out of 34 samples. The shepherd was only slightly less accurate than a standard thyroid biopsy. This offers the possibility of a cheaper, less invasive approach to diagnosis of the illness said Donald Bodenner, M.D., PhD, the study's senior investigator.
That theory doesn't hold if all 10 dogs are missing the same 20% due to a common failure mode.
