Abstract
The purpose of this study is to analyze alternatives to increase the effectiveness of thermographic images technique for the early diagnosis of breast cancer using only superficial temperatures of the breast skin. A 2D hemispherical geometry of the breast was considered to solve the bioheat transfer problem using the commercial software COMSOL. The thermal analyzes were performed considering the early stages of the disease, where cases are more difficult to diagnose. Firstly, stationary temperatures on the breast skin surface were acquired for mammary tissue with and without tumor. Then, a heat rate in the square wave form was inserted on the skin surface to increase the thermal contrast between healthy and tumor tissue. The results obtained demonstrate that heating the breast skin surface can significantly increase the thermal contrast for tumors located in deeper regions.
