Cancer Detection System

A cancer detection system, comprising:

• a light generator for emitting examination light;
• an irradiating fiber for propagating the examination light emitted from the light generator to irradiate tissue with the examination light;
• a collecting fiber for receiving and propagating the examination light scattered by the tissue;
• and a
• spectrum detector for detecting and recording the scattered examination light from the second light guide to measure the spectrum of the detected light;
• a fibre optic plate having a first end face which transmits light entering one of the end faces to the other, with the two dimensional position of the light being maintained;
• the irradiating fiber and the collecting fiber being arranged on the second end face of the light guide plate so that the light guide plate receives the examination light from the irradiating fiber and illuminates a region of the tissue corresponding to the location of the irradiating fiber and so that the light guide plate exits the examination light scattered by the said region of the tissue into the collecting fiber, and
• a moving mechanism for moving the irradiating and collecting fibers with respect to the tissue to select a plurality of distinct regions of the tissue for measurement.
