The invention relates to an irradiation device for treating skin changes, especially skin tumours, said device comprising a radiation unit for radiation of a phototoxic substance accumulated in the skin changes, a cytotoxic effect arising in radiation of the phototoxic substance. The selected phototoxic substance forms new substances, so-called photoproducts, in radiation from the radiation unit, and the radiation unit is adapted to generate broad spectrum radiation in a selected wavelength range, in which a relatively high photoabsorption in the phototoxic substance and a relatively low photoabsorption in the photoproducts are obtained. The invention also relates to a method for radiation of a phototoxic substance and a method of determining a suitable wavelength range for treating a skin change. |
