Abstract

By using laser radiation on rats which had body surface malignant tumors, we observed the pathological changes in these tests and took further steps to research the influence of photodynamic effects on remaining cancer cells. We observed that the PDT treatment provided maximum security in these malignant tumor treatments. It enhanced the killing ability on the tumor tissues and retained the normal tissues in the greatest limitation. But it may be dangerous to kill the remaining cancer cells in peri-carcinoma tissue when using Nd:YAG laser for continuing illumination. Our research confirms that the effects of combined use of the HPD and continued illumination are better.
