Implantable, flexible LED detects cancer [video]

Please get a human editor to read these before posting. "Its" and "It's" are not interchangeable, dammit.

Due to applied funding and the work accomplished during my lifetime, new innovations that could save my life keep being announced. Problem is, not only will most of them never make it to the marketplace, but the FDA will block them at every chance. Since I am getting older, and wiser... I have decided to stop developing technologies that can save lives and instead switch to lethal weapons systems, so at the least I can spend my final years drinking beverages on some untarnished beach while the rest of the world continues to either whittle away their time to fruitless behaviors, or block that which they simply do not care to understand, or acknowledge as useful. Whatever. Nice cancer detection concept, by the way.

This article describes the LED technology but no information related to HOW this can detect cancer! Yes, it can be implanted- but then what? For instance, how is it monitored externally? Is it viewed by doctors periodically? It seems to give the impression that the patient's prostate will start to glow indicating growth of cancer...
Please try to give a complete description of the technology- and its application- and avoid misleading titles?
