The main reason is that, the shorter the wavelength of electromagnetic radiation, the more energy each photon (light particle) carries. When we get into ultraviolet and shorter wavelengths, the photons carry enough energy to break bond holding molecules together. This is bad for us since we depend on complex molecules having the proper structure. This kind of damage to DNA can result in mutations that pose a cancer risk.
