Medgadget, Nov. 14, 2006 Here at Medgadget, we are big fans of anything that involves laser beams and nanotechnology. So when the National Institute of Health started funding the use of these technologies for the early detection of breast and prostate cancers, our ears perked right up. Over four years of research and pilot studies by scientists at Fairway and The University of Texas Medical Branch at Galveston (UTMB) indicates the system can detect breast cancer tumors potentially as small as 2 millimeters, five time smaller than most malignant breast tumors detected currently.
