Abstract
The aim of this work is to perform a numerical evaluation of thermal behavior of two breast cancer types: ductal carcinoma in situ and invasive ductal carcinoma. Analysis is developed considering a two-dimensional geometry that characterizes the anatomy of a breast. The thermal behavior is obtained using numerical solution of bioheat equation, i.e., Pennes’s equation, solved by commercial COMSOL software. Temperature profiles of healthy and compromised breast are compared in specific tumor regions and on skin surface. The results indicate that the greatest temperature variation occurs in invasive ductal carcinoma case. These results can significantly help in the development of new diagnosis techniques using thermal images obtained by infrared thermography.
