Abstract

A probe, and an apparatus incorporating the probe, for detecting tissue abnormality, particularly precancerous cervical tissue, through fluorescence spectroscopy are disclosed. In vivo fluorescence excitation and detection can be accomplished easily and accurately using a probe whose tip conforms to the surface of the cervix. In addition, a higher number of fiber pairs provides more information and, therefore, more accurate diagnosis.
