Abstract
Abstract Cancer of the oral cavity is treated by sensitizing malignant and premalignant tissue and non-selectively irradiating the entire oral cavity with a destructive laser. The strength or intensity of the light is adjusted so that nonsensitized tissue is not damaged. A special holder adapted to permit irradiation of the entire oral cavity from two fiber optic diffusers is also disclosed.
