Handheld probe shows great promise for oral cancer detection
Date:4/30/2012

iopsy. Based on a doctor's visual inspection, medical practitioners remove a sample of tissue from the patient and send it off to a pathologist who will examine the tissue under a microscope to check for abnormal or malignant cells.

Results will be sent back to the doctor for the next round of diagnoses or surgery; the whole process can take up to several weeks. Not only is this process time consuming, it can be costly, invasive and painful, often leaving scars.

"Due to the lack of real-time efficient oral cancer screening tools, it is estimated that approximately $3.2 billion is spent in the United States each year on treatment of such cancers", Dr Zhang continued.

The researchers, from the University of Texas at Austin and the commercialization partner NanoLite Systems, Inc. are now planning clinical trials with a view to gaining approval from the Food and Drug Administration (FDA). They envisage that, with a few adjustments, the device could be built for a quarter of the price it costs to build the microscopes that are currently used in diagnosis, which is around $300 000.
