<p>Disclosed are a method and an apparatus for killing tumor cells selectively. As one aspect, a method for killing tumor cells selectively is disclosed, which is characterized by comprising a step of irradiating tumor cells with pulse light (UV pulse flash) having continuous emission spectra ranging at least from 230 to 270 nm outside a living human body or a living body of a non-human animal or in a living body of a non-human animal. Preferably, the UV pulse flash has an integrated radiation amount per unit area that is achieved at a distance of 8 cm from a light source having an integrated output of, for example, 90, 180-7100 or 14200 J, i.e., an integrated radiation amount per unit area of 6, 12-480 or 960 J/cm2 in terms of an energy originated from the wavelength of UVC. The step of irradiating with the UV pulse flash is preferably carried out, for example, within 1 minute. The UV pulse flash is preferably emitted from a xenon flash lamp. As another aspect, an apparatus for treating tumor tissues is disclosed, which is characterized by being equipped with a light source of the UV pulse flash.</p> |
