Prostate cancer detected by dogs with more than 90% accuracy

New research has supported the idea that dogs could one day be used to sniff out cancer, after a study found that trained German Shepherds were able to detect chemicals linked to prostate cancer from urine samples with incredibly high accuracy.
A study carried out by the Department of Urology at the Humanitas Clinical and Research Centre in Milan had two German Shepherds sniff the urine of 900 men, 360 of whom had prostate cancer and 540 who didn't. One dog was successful at identifying prostate cancer in 98.7 per cent of cases, while the other dog achieved 97.6 per cent accuracy.
It is the latest research in a series of studies stretching back decades, and boosts the hope that canines could help doctors identify various human cancers and diseases. 40,000 new cases of prostate cancer are reported every year, making it the most common type of the disease among British men.
