As the number of breast cancer patients increases, non- invasive and accuracy diagnosis of breast cancer is required. It is expected that there is diagnostic potential in examining the nonlinear elastic properties of soft tissues. The measurement method of the nonlinear elasticity of tumor in breast is needed. Therefore, we propose the robotic palpation system for diagnosis based the nonlinear elasticity. Here, we report the measurement of the nonlinear elastic properties of breast tissue components. The nonlinear elastic properties of breast tissue were investigated with a creep test. The three parameters of the nonlinear elastic model were acquired. In conclusion, two of these parameters are significantly different among the components. There was indicated that the magnitude of parameter is determined by tissue structure. There was suggested that the difference in parameter distribution causes the difference in dynamic response of breast tissue.
