The Nose Knows: Cancer-Sniffing Dogs to the Rescue!

Dogs get their noses into everything. They can sniff out where you've hidden the treats, they know you've been petting the dog next door (you cheater), and they greet your guests by shoving their noses into their privates.
"Why hello, Friend of Hooman's crotch. Pleased to make your acquaintance."

And now we're training dogs to find cancer.

It’s all one big game," said Dr. Otto.

The goal is to pinpoint the chemical marker the dogs have been smelling, which will then help scientists create a handy sensor used for detecting cancer present in the body. And since early detection of cancer is one of the most important parts of successful treatment, figuring this out will be a huge breakthrough in the field.
