Radiofrequency (RF) hyperthermia therapy is a cancer treatment that consists of raising the temperature to induce thermal damage of the tumor tissues. The efficacy of this therapy depends on the frequency and power of the radiofrequency wave and the exposure time that defines the thermal dose that receives the tissues. Through mathematical models, it is possible to quantify the thermal dose caused by the hyperthermia process and to determine the degree to which it occurs. In this paper, a parametric study of the frequency, power, and exposure time of heat induction using RF hyperthermia is carried out. This study allows knowing if the damage caused is first-degree, second-degree, or third-degree burn. The results reveal that the three parameters are relevant to define an adequate treatment where the tissues do not reach a thermal dose above the second-degree burn.
