Detecting cancerous tissues in human body by means of fiber fluorescent spectroscopy

This work´s purpose is to present a non-invasive optical method of diagnosing cancerous and otherwise pathological tissues. The optical method and devices proposed in this paper can compete with alternative methods presently employed, in that - among other things - they are non-invasive (therefore completely safe to the patient) and they are very sensitive. There is no need to take tissue samples for these methods and devices as they can be performed in vivo. The methods presented in this paper are referred to as those involving fluorescence spectroscopy.
