Abstract
Breast cancer is one of the deadliest diseases in women right now. Although surgery is a solution to it, and breast cancer can be cured by other treatments besides surgery. Effective use, of the radiofrequency (RF) system in hyperthermia treatment (HT), helps to reduce the size of the tumor so that it can be surgically removed. In HT, the temperature of the tumor is heated above 42 °C, and the temperature of the surrounding skin is kept below 38 °C. In this paper, a 2D breast model with two spherical tumors of 10 mm diameter are created using COMSOL Multi Physics Solver Simulator. Temperature variations inside the breast and tumor are examined with the electrostatic modeling and heat flow modeling using finite element method (FEM). In HT, it is essential to maintain the highest amount of RF focusing on tumor, and heat flow inside the tumor. The bio-heat equation is solved for known boundary conditions. The mathematical analysis, and simulation results for heat flow, temperature distribution, flux intensity, and density near the surroundings and inside the tumor, show that highest RF focusing in and around the tumor tissues, has been achieved that avoids damage of surrounding normal tissues.
