Dogs and Cancer, Take Two

The answer you entered to the math problem is incorrect.

A joke relates how a patient goes to the doctor, and during the visit the doctor's Labrador retriever sniffs him. Later, the patient finds a charge on his bill that he didn't recall. His doctor explains, "Oh that's for the Lab test."

Humor meets science. A study shows dogs can detect lung and breast cancer by sniffing a patient's breath. Apparently, they are successful in 88 to 97% of cases. The experiment included over 80 cancer patients, and a similar number of controls.
