Abstract: Cancer diagnosis device contains an endoscope comprising a light pipe used to transmit light beams from respective light sources and an image guide used to observe the flesh of the organism during both diagnosis and treatment. The tip of the endoscope faces toward the focuses where a photosensitive material having an affinity to the focuses of cancer has been absorbed so that a treatment for cancer can be performed by exposing the organism affected by cancer to the laser beam. The attainable the laser beam within a focus is thus increased by the use of the laser beam pulse from a first laser beam pulse source.
