David L. Shenkenberg

To localize a tumor in the bladder, doctors routinely perform a cystoscopy, a procedure that involves inserting a lensed, lighted tube into a patient to enable their search for potentially cancerous sites. Cancer can easily be missed because doctors rely only on a narrow optical tube and their eyesight for visual analysis. Fluorescent labeling and other markers have been suggested, but these methods only stain for expected changes. Raman spectroscopy can produce a complete biochemical profile of the tissue and can be integrated into a cystoscope through fiber optics. For the initial...Read full article
