The quantity and identity of specific protein markers in the human saliva can be used as an early, non-invasive diagnostic test for breast cancer that can even be conducted by dentists.

Such were the findings of a new study by researchers at The University of Texas Health Science Center at Houston.

The study describes how the onset of breast cancer produces a change in the normal type and amount of proteins in glandular secretions from the salivary glands. The protein profile in a healthy person is altered by the presence of cancer.

The study is being applied to a “lab-on-a-chip” technology platform developed by biochemists at The University of Texas at Austin. The ultimate goal is to bring this type of diagnostic test, which is capable of detecting the presence of cancer before a tumor forms, into the dental office or other health care facilities.

The technology aims to improve the ease and effectiveness with which dental professionals and other health care providers can provide quick, accurate diagnostic information and physician referrals to their patients.

So, one day, your visit to the dentist may not only be for dental care but may also be for breast cancer diagnostic tests.
