A treatment method is disclosed capable of reducing the burden on a patient and enhancing the effect of killing tumor cells. The method includes administering an antibody-photosensitive substance into a vein; inserting an endoscope from a mouth, a nose, or an anus and bringing the endoscope to a vicinity of a tumor after the administering of the antibody-photosensitive substance into the vein; placing an optical fiber into the tumor or in the vicinity of the tumor; irradiating at least one of the tumor, the vicinity of the tumor, or a regional lymph node with a first near-infrared ray by the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane in the tumor cell with a second near-infrared ray after the irradiating with the first near-infrared ray, the second near-infrared ray having a shorter wavelength than that of the first near-infrared ray.
