In the study the dogs are able to identify correctly 63 of 66 urine samples berkanker and healthy.
Nevertheless, the experts would not rush to conclude the ability of dogs to detect cancer, given the small scale study and further research is needed to prove it.
When later shown a dog can detect accurately, experts believe this method will be more effective and accurate than blood tests to determine the prostate-specific antigen (PSA) which has been the standard examination to screen for prostate cancer.
