Colon Cancer Can Be Sniffed Out By Labrador Retriever

In this article, a Labrador, Marine, was being trained to be a water rescue dog, but during training, Marine showed the ability to sniff out the chemical changes in the breath of patients that had cancer. With a 98% accuracy rate, and she was able to catch the disease which a stool same test may have missed it, is quite astounding.

With research on how Marine sniffs out the disease, researchers believe that chemicals released into the stool, get absorbed into the bloodstream and out through the lungs as blood circulates back through the body. This new finding has lead researchers to start developing a sensor to detect the chemical changes in our breath to detect the development of cancer in our bodies.

This article was interesting to me because, people say, dogs are a mans best friend and that dogs can sense our feelings. Now we know that they can sense more than just our feelings, but also chemical changes in our body. A question that is brought to mind after reading this is if dogs can sniff out more than just cancer.
