Dogs Detecting Cancer in Humans

The sense of smell is a dogs primary sense. Sniffing allows dogs to take in air quickly to specifically identify the odor several meters away. Their sense of smell is extremely sensitive with over 220 million smell-sensitive cells within their nose compared to only 5 million in humans.

For this reason, dogs readily assist us in the community to track everything from people to drugs to explosives.

It's no surprise that dogs may have a use in human medicine. It has been fairly well documented that dogs can detect low blood sugar in diabetics. A recent study by the Pine Street Foundation in California has demonstrated a dogs ability to detect lung and breast cancer in humans based on breath samples.
