They are quick to point out that neither of these body manifestations means that a woman will certainly develop cancer, but they found that variations ("snips") in the ABCC11 gene were linked to very bad underarm odor and wet ear wax, and they developed a test that identifies the gene variations in thirty minutes. Researchers say that this discovery could make it...
