Analysis of Cancerous Tissue Temperature in the Breast During Hyperthermia

In this paper, the breast cyst diagnosis based on the surface temperature profile is proposed. The temperature profiles of normal breasts and breasts with cyst have been investigated. Heat transfer inside the breast is modeled by the Penne's bio-heat equationand solved by the finite element method using COMSOL Multiphysics software. A two dimensional (2-D) cross-section of the breast is modeled by a semicircle, whereas the cyst is modeled by a small circle. The temperature distribution on the breast surface for the normal breast and the breast with a cyst of various sizes were determined. The results show the difference in the surface temperature profiles of the normal breast and of the breast with a cyst of different sizes.
