Does cancer have an odor? Pet owners tell amazing stories of dogs sniffing out disease and saving their lives

Cancer can be a silent deadly killer.

But dozens of pet owners have revealed how their dogs were able to detect different forms of the disease before the doctors did to help save their lives, using their powerful sense of smell.

It’s estimated a dog’s sense of smell is 10,000 to 100,000 times more powerful than humans, meaning some breeds can detect a substance at a concentration of one-billionth of a teaspoon.

Their supreme sense of smell has been harnessed to detect a range of things, from detecting drugs and explosives to tracking down criminals.

Diabetic alert dogs can even sniff out changes in the blood that occur when blood sugars becomes too low or too high.

Kim Reed, a retired accountant at American Airlines from North Carolina, said her dog helped detect her breast cancer.
