To reduce the exposure to radiation by selectively destroying cancer cells in a living body by a cancer cell destroying system without being limited by the kind of cancer or the position of an affected part.
The cancer cell destroying system for destroying cancer cells in the living body comprises a photocatalyst infusion unit 10 for infusing a photocatalyst into cancer cells, a radioactive formulation infusion unit 20 for infusing a radioactive formulation emitting radiation into the cancer cells. The radioactive formulation is, for example, the one emitting gamma rays, and such a radionuclide is used as is easily taken in cancer cells or in a region where cancer cells are present. The photocatalyst is titanium oxide. The cancer cell destroying system also has a radiation measuring part 9 for confirming the state of attenuation of radiation infused into the living body.
