Odor of body fluids can make it possible for the scientists to track lung cancer at its initial stage, suggests a new study.

The findings of the study conducted on mice could assist in revealing early stage lung cancer in humans.

The lead study author Gary K. Beauchamp, a biologist at Monell Chemical Senses Center said, “This work already proves, at least in principle, that tumors — in this case lung cancer tumors in mice — result in a change in odors that ought to be useful for diagnostic purposes.”
