Modern versatile thermographical techniques have recently renewed the research direction for the early detection of the breast cancer. An unusual temperature field on the breast surface can be induced by the presence of a malignant tumor, due to a higher metabolism of the cancer cells comparing to the normal ones. Localising the tumor and determining its morphology based on the temperature field on the breast surface is an ill conditioned problem that needs a huge computation effort. We investigate the influence of the breast tissue thermal and geometric parameters on the surface temperature field. Also, some techniques for determining the affected area are commended. A simplified model of the breast geometry is adopted in order to obtain an analytical solution for Pennes’ equation. The results are extremely useful for the analysis of the real breast geometry, drastically limiting the investigation area
