Abstract: The present invention relates to a photodynamic therapy apparatus for local targeting in cancer treatment. More specifically, an endoscope is placed in the center of an end portion of a probe used in photodynamic therapy and a plurality of optical fibers are arranged along the edge thereof, so that a lesion site is irradiated with a plurality of lights while the plurality of optical fibers of the probe receive lights from individual light sources, respectively, to perform light irradiation individually. Furthermore, the present invention relates to an apparatus, wherein unnecessary damage to normal tissues is minimized by controlling light irradiation regions, for instance, by defining light irradiation regions encompassing a lesion site from an image provided in real time through an endoscope disposed at an end portion of a probe and allowing only individual light sources irradiating the defined light irradiation regions to emit lights to achieve local light irradiation.
