St. Petersburg, Florida -- Cancer sniffing canines are helping to save lives.

Claire Guest, chief executive of Medical Detection Dogs, runs a charity that trains dogs to sniff out cancer, and when she took the dogs out, one of them started jumping and bumping her head at Claire's chest. Turned out, Claire had breast cancer and didn't even know it.

"Without any question, I would not be as well, and even perhaps alive, today had Daisy not drawn my attention to it," she says.

The animals are taught to identify urine samples from bladder cancer patients because cancer cells give off a specific smell that dogs can identify.

Scientists say a canine's sense of smell is so refined that dogs may one day be able to decipher between different types of cancer. Scientists are also trying to develop technology that sniffs out cancer just like trained canines can.
