<p>A method of detecting abnormal epithelial tissue. The method includes the steps of providing a light source, providing a housing having an opening defined therein, inserting the light source into the housing, illuminating an area of epithelial tissue with incident light emitted from the light source that is directed through the opening in the housing, wherein at least a portion of the incident light is reflected from the area, thereby creating reflected light having has at least one wavelength, and viewing the reflected light. The housing is preferably opaque.</p> |
