Resumen:

Cancer is the second leading cause of death worldwide and breast cancer is one of the most frequently diagnosed cancers. Nowadays, thermography technique has emerged as a noninvasive and prospective method to complement mammography and to improve the efficiency of early and overall detection of breast cancer. In this work, analytical and numerical strategies are employed to solve a bioheat transfer equation with rapidly oscillating coefficients. The macroscale thermal conductivity is computed by applying the asymptotic homogenization technique, the local cell problem is solved analytically and the macro-scale problem is solved via finite element method. We considered thermal anisotropy and found that it provides extra information regarding the thermal profile on the breast surface near the cancerous area. © 2017 Centro Servizi d'Ateneo S.r.l.
