Two highly trained German shepherd dogs have uplifted the hope why dogs are man’s best friend with their outstanding sniffing ability to detect compounds linked to prostate cancer.
The two 3-year-old German Shepherd Explosion Detection Dogs, both females, were strictly trained and with their enhanced olfactory system, they were able to identify prostate cancer specific volatile organic compounds in urine samples of 900 men, of which 360 of them have prostate cancer and 540 do not – with more than 90 percent accuracy.
The study was published in the Journal Of Urology and the cross-sectional design for diagnostic accuracy was done at the Italian Ministry of Defense Military Veterinary Center.
Hopefully, trained dogs like these could be an alternate means of detecting prostate cancer with accurate results against the currently prevailed detection method known as the PSA test (Prostate Specific Antigen Test) which is accomplished through blood test, physical examination and biopsy.

Went 43 radiations for it this time last year. Now we need some dogs to cure it.

Hope even the untrained dogs have this ability. 🙂

I think, human noses can also detect a lot with proper training. I suggest to introduce new diagnostic methods to the medical school curricula. This could save millions on expensive lab equipment and tests.

Yeah, there was also a research that claimed human nose can distinguish 1 trillion smells. http://sparkonit.com/2014/03/21/humans-are-better-smeller-than-thought-can-distinguish-1-trillion-smells/
