The dog is the man's best friend, or the man's best friend.

In these studies it has been proven that dogs are the best detectors of prostate cancer, a very common type of cancer that only affects men and can end in death. How do they do it?

Through your nose. We all know the complexity that the olfactory system has in dogs, as they are able to store smells in your mind and remember them even if it takes several years.

In this case a group of dogs joined so that they could differentiate the smell they were looking for. They offered urine samples from different types of people, from both healthy and sick patients. The group of dogs made the diagnosis in 87% of the cases.

This can be a great scientific advance to prevent or be able to treat in time this illness that causes so much suffering.

The professionals involved promise to keep working to get results and some even more accurate statistics. Scientists want to train different groups of dogs for different diseases, cancer or others and thus can continue advancing and saving lives.

This is not the first experiment of this kind to be performed. There have been many more that have proven that dogs can detect cancer without the need for major tests, although it was the first to achieve such a high hit rate.
