High-energy Nd:glass laser for oncology

The use of high energy solid state lasers for the treatment of human skin neoplasia was based on the experiments and clinic studies by Helsper and Goldman (1964), McGuff (1966). The heat of precise local volume is emitted due to the pulse laser radiation. The thermal effect results in the superficial necrosis of tissues with their integrity destruction, vascular repture accompanied by bloodstoke in some cases and by capillary embolism in others. Obvious tumour destruction is note only in case of high density irradiation. General tumour destruction depends on biological neoplasia features as well as the laser type.
