1. A medical examination device comprising:

  • an illumination source, wherein the illumination source includes a lamp and a plurality of selectably engageable filters for generating a beam of light of a selected wavelength;

    a light directing device for selectably directing the beam of light from the lamp in a first beam direction or in a second beam direction;

    a visualization unit that receives the beam of light whenever the beam of light is directed in the first beam direction and radiates a tissue with the received beam of light, the visualization unit visualizes and captures a macroscopic view of the tissue from a first emitted light beam emanating from the tissue illuminated with the received beam of light;

    a fiber optic probe having a shaft, a handle, and a fiber optic bundle having a plurality of excitation fiber optic strands and a collection fiber optic strand, wherein whenever the beam of light is directed in the second beam direction the excitation fiber optic strands receive and transmit the beam of light to a selected microscopic tissue area at a site of contact with a distal end of the fiber optic probe, and wherein the collection fiber optic strand collects a second emitted light beam emanating from the tissue area illuminated with the beam of light transmitted by the excitation fiber optic strands;

    a detector for detecting a plurality of emission wavelengths from the second emitted light beam; and

    a processor for calculating from the emission wavelengths a probability that the tissue is diseased.
