Breast elastography consist of static and dynamic method. The paper deals with morphologic characterization of breast lesions and typical symptoms like: mass ventralisation, size change, switch-off sign and posterior boundary imaging. The recent studies of dynamic elastography implementation into breast cancer screening are presented. In the shear wave elastography red colour, irregular shape or maximum stiffnes above 160kPa the upgrade from BIRADS 3 to 4a should be made. If the lesion is homogenous, blue and with stiffness < 80kPa them safe downgrade to BIRADS 3 could be considered.
