The selective killing effect of special wavelength light in the treatment of human superficial cancer.
The authors discovered that 0.4-micron to 1.1-microns wavelength light can selectively kill superficial cancer tissue in the human body. Light at a density of integral power 1 to 6 W/cm2 will kill tumor but will affect normal tissues less. The model KS-1 phototherapeutic instrument was made according to these principles and used to treat 34 patients who had a variety of cancers, including carcinomas of the oral cavity, skin, and cervix. The 25 cured patients were then monitored for 1 to 4 years. No side effects were found. Currently there are several hospitals in China that use this instrument for the treatment of some kinds of carcinoma.
