实验表明,在特定情况下,YAG激光对口腔癌、食道癌有选择性作用。 实验1 用YAG激光,以特定的方式,同时照射人口腔癌及近旁正常组织.通过观察和病理切片分析,可以明显地看到选择性作用,在激光照射下,癌组织颜色变深;2天后脱落,正常组织无明显 Experiments have shown that YAG lasers have selective effects on oral and esophageal cancer under certain conditions. Experiment 1 YAG laser was used to irradiate human oral cancer and adjacent normal tissues in a specific manner. Through observation and pathological section analysis, the selective effect can be clearly seen. Under the laser irradiation, the color of the cancer tissue becomes dark; 2 days later Shedding, no obvious normal tissue
