In this study, theoretical analysis of the Pennes biotransfer model was developed, whose object studied was a region with cancer, more specifically kidney cancer, where a minimally invasive method of thermal ablation with variation of the electrical conductivity was used to treat it. For this purpose, a radiofrequency generator was simulated for the coagulative necrosis of cancer cells as a heat source for the bioheat transfer model. The software MATLAB, was used to perform the numerical simulations using the tool pdepe, obtaining results for a model with a fixed electrical conductivity value (0,34 S/m) and variable electrical conductivity (0,34 to 0,51 S/m) according to the temperature, in order to demonstrate the importance of this parameter in the simulation in living tissues. Therefore, it was possible observe the influence of electrical conductivity in heat treatments for different diseases, without causing greater damage in the vicinity of uncompromised tissues and organs.
