But nosy ones have provided inspiration to a laser research team working on early cancer detection methods to devise a breathalyzer-type tool that could significantly improve survival rates for suffering millions.

Researchers at University of Oklahoma are reportedly working to create a sensor to detect bio-marker gases exhaled in the breath of a person with cancer, picking up on earlier studies showing that dogs can detect cancer by sniffing the exhaled breath of cancer patients.

In a study published two years ago, it was found that dogs identified breast and lung cancer patients with accuracies of 88% and 97%, respectively by smelling breath samples.

It has been proven elsewhere that gas-phase molecules are uniquely associated with cancer but the team will use nanotechnology to improve laser performance and shrink laser systems, which would allow battery-powered operation of a hand held sensor device.
