Abstract: Thermoregulation of human body maintains the body core temperature at 37°C. Body temperature rises due to the illness such as fever or heat stroke. The abnormal temperature distribution in breast tissue is caused by breast diseases like cysts, tumor, cancer etc. Most of the breast tumor, normally, develops in lobules and milk ducts at glandular layer of breasts. Medically, infrared breast imaging (thermography and mammography) is used to diagnose breast cancer, in which temperature distribution analysis plays a vital role. In this study, finite element method is used to solve one dimensional unsteady state bio-heat equation to find temperature distribution in the layers of normal and tumorous breast tissue with different size and location of tumor from areola. The results show that temperature variation of breast layers depend on size and location of tumor from areola. The temperature distribution of layers of tumorous breast tissue is higher than normal breast tissue. From the simulation results, it is observed that temperature of tumorous breast tissue achieved steady state earlier than normal breast tissue.
