Researchers say it didn't matter if the patients who gave the breath sample had recently smoked. The findings have many hoping an earlier detection system, based on supersensitive canine noses, won't be far off.
"If we were able to take what they're doing and translate it into a test, there is a possibility, and let me emphasize a possibility, that we could take this and use it as a screening test," Dr. Len lichtenfeld said.
Researchers say dogs noses have 220 million odor detectors, which give them a superior sense of smell. That's why they're already used to sniff out drugs and bombs.
