Prostrate Cancer Sniffing Dogs

That's what Dr. Barkman calls a real LAB report.
Canines have around 220 million olfactory cells in the nose (humans have about 6 million) enabling some dogs to smell chemicals released by cancerous tumors.  In a study presented at the 2014 American Urological Association's annual meeting, researchers reported that two dogs trained to identify these chemicals smelled the urine of more the 650 patients, and demonstrated a 98% accuracy in detecting prostate cancer.  Currently, blood tests are used to diagnose the disease, and have an accuracy rate of about 80%.
