One Breath Into This Breathalyzer Can Diagnose 17 Diseases

A single breath into a newfangled breathalyzer is all doctors need to diagnose 17 different diseases, including lung cancer, irritable bowel syndrome and multiple sclerosis, a new study found. The breathalyzer could identify each person's disease with 86 percent accuracy, the researchers said. The technology works because "each disease has its own unique breathprint," the researchers wrote in the study.
