(PhysOrg.com) -- The gentle touch of a brush on the tongue or cheek can help detect oral cancer with success rates comparable to more invasive techniques like biopsies, according to preliminary studies by researchers at Rice University, the University of Texas Health Science Centers at Houston and San Antonio and the University of Texas M.D. Anderson Cancer Center. A new test that uses Rice's diagnostic nano-bio-chip was found to be 97 percent "sensitive" and 93 percent specific in detecting which patients had malignant or premalignant lesions, results that compared well with traditional tests.
