Cancer disease is one of the most important cause of mortality recently in the world. One of the most effective complement way for curing cancer is thermal therapy. Accordingly laser emission on cancerous tissue that saturated with gold nano-particles, Cancerous cell temperature gets high and gives rise to death of Cancerous cells. This way has encountered with so challenges which one of most important is harmful effect on healthy tissue that some methods are proposed for prevention. One of this method is application of pulsed laser or thermal strategy. In this study, methods for application of tow-energy equation and dynamic laser are assessed and revealed that application of tow-energy equation has accureate out comes and in comparison to bioheat equation, tissue temperature is less increased, there for less harm results. Application of dynamic laser diminishes this temperature increase, so damage to healthy tissue is significationtly decreased. The effect of less intensity is assessed in this study, that reveals laser intensity has direct relation with temperature increase. The greater emission intensity, the faster tumor area temperature and in comparison to static laser, this temperature increase will be slowly. The assessment of effect of gold nano-particle volume fraction on thermal strategy reveals that volume fraction has direct relation with thermal field and the lesser volume fraction of tumor, the greater temperature velocity and thermal field. Simulation strategy is used for assessment of a forementioned items and COMSOL software is used for this simulation.
