During my last visit to the dentist, I received a new test for oral cancer. A Vancouver-based company, LED Medical Diagnostics Inc. (LED-MD) has developed the VELscope System in partnership with the British Columbia Cancer Agency. The test involves shining a Velscope LED light into the mouth. Abnormal tissue is supposed to show up as a dark, irregular area. Fortunately, my test came up negative. The site link below explains the inadequacy of the standard white light checks made by your dentist and the danger of having undiscovered oral cancer. There are also details about the use of the Velscope device.

The VELscope isn't the only oral cancer discovery tool available to dentists. Zila Pharmaceuticals in Phoenix, Ariz., sells the ViziLite Plus system, which can also detect abnormalities in the oral cavity. The patient rinses his or her mouth with a dilute acetic acid solution so that damaged tissue appears white when viewed under ViziLite's diffuse low-energy wavelength light.
