A tissue detection system and methods for use thereof are provided. The tissue detection system facilitates stimulating fluorescence via illumination in an area or areas of interest in the human body, detecting non-visible or not easily visible areas of interest subject to such stimulation, and identifying these areas of interest efficiently. The tissue detection system can employ a probe for facilitating illumination/stimulation of a tissue of interest, at least one emitter for generating radiation applied to the tissue of interest, and at least one detector for capturing radiation for the fluorescing tissues of interest.
