Imagine being able to detect cancer through smell. It is certainly within the realm of possibility. The human skin releases chemicals known as volatile organic compounds (VOCs) in differing amounts, which in turn generates unique scents. And while our noses are unable to detect them, a canine's sensitive nose can. Dogs have been trained to "sniff out" tumors and to detect changes in the odor of urine, which could indicate bladder cancer. Researchers now hope to use this premise to develop a noninvasive test to diagnose skin cancer.
