That's better than chance. But it's not clinically significant.

Canine scent detection of cancer was something that was anecdotally discussed for decades, but we felt it was appropriate to design a rigorous study that seriously investigated this topic to better evaluate its effectiveness.

It's all about early detection. If you find the cancer early enough, you can give patients options.

These were not super dogs. They were just ordinary household pets.

If dogs can detect cancer early, we wanted to investigate it. If you get time, you get hope.

Cancer cells emit different metabolic waste products than normal cells. The differences between these metabolic products are so great that they can be detected by a dog's keen sense of smell, even in the early stages of disease.

When we heard anecdotally that there was a device out there that might be able to detect cancer at its earliest stages, before it even shows up on an MRI [magnetic resonance imaging], it was something we wanted to pursue.
