PURPOSE:To surely and easily treat a desired section with a simple structure by providing a semiconductor material having a photocatalytic effect in at least a part on the outside surface of a chemical luminous body consisting of a chemical light emitting agent. CONSTITUTION:The chemical luminous body 2 is detained in the malignant tumor, for example, cancer tissue 9, generated on the inner side of the inlet part 8 of the uterus 7 of a patient in the state in which the semiconductor electrode layer 6 applied on the surface of the chemical luminous body 2 is held in contact with the cancer tissue 9 when the chemical luminous body 2 is inserted into the above-mentioned inlet part 8. An oxidation reaction takes place on the semiconductor electrode layer 6 when the chemical luminous body 2 emits light for a specified period of time and the illumination light falls onto the semiconductor electrode layer 6 in such a manner. The cancer tissue 9 is then killed by the photocatalytic effect. The light emission of the chemical luminous body 2 ends upon lapse of the specified period of time. The chemical luminous body 2 is pulled to the outside of the body by holding yarn 3 after the treatment ends. |
