US researchers develop new tools for oral cancer detection

Release date: 2010-04-13



American researchers say they have developed a new, non-invasive and painless way to diagnose oral cancer.

Researchers report in the new US issue of Cancer Prevention Research that the new test tool is similar in shape and size to a toothbrush and has a built-in chip. Not only does it have non-invasive and painless benefits, but it takes only 15 minutes to test. Ordinary biopsy usually takes several days to get results.

Researchers from Rice University and the University of Texas say the new nanobiochip is very close to invasive technology in detecting the sensitivity of oral cancer, reaching 97% of invasive technology sensitivity. It has reached 93% accuracy in detecting patients with malignant lesions or precancerous lesions.

The study's leader, John McDevitt of Rice University, said in a statement: "One of the most important findings of this research is that this non-invasive small instrument can be used to detect oral cancer. Pathologists get nearly the same result."
