Dogs sniff out prostate cancer
03:17 Man's best friend might also be able to give him a heads up about cancer.
The latest evidence of a dog's ability to detect cancer came from French researchers this week. A dog was trained to identify urine from patients with confirmed prostate cancer and then to discriminate those samples from urine from healthy men.
In early tests, the dog produced fewer false positives than the commonly used PSA test, setting the stage for another detection method.
This in on way means dogs will be running around the hospital
sniffing urine, according to WebMD. If researchers can identify which chemical the dog is reacting to, they hope to develop an electronic nose.
