Study says: Dog can Sniffs out Prostate Cancer
A new research says that dogs can sniff out signs of prostate cancer in human urine. A group of scientists from Tenon Hospital in Paris reported at the American Urological Assn. that dogs can be trained to detect the characteristic odor of unique chemicals released into urine by prostate tumors.The detection of prostate cancer on humans is highly controversial, which means the study sets new way to identify men who are most at risk from the cancer. Some researchers think many patients are treated unnecessarily because existing tests of prostate aren't accurate enough. For this study, two researchers spent a year training a Belgian Malinois shepherd, a breed already used to detect drugs and bombs. The dog was trained to differentiate between urine samples from men with prostate cancer and men without. So far the dog correctly classified 63 out of 66 specimens.
Urine tests can turn up signs of prostate cancer. Some types of molecules give a distinct odor to urine. The problem that the scientists encounter, is that they do not know what this molecule is, and the dog cannot tell us." Still, the report could represent a significant development since cancer often goes undetected until it is too late to treat.
