Breast cancer is a major health problem that warranted efforts to be paidin order to increase the diagnostic capability of the routinely useddiagnostic aids. Ultrasound elastography is one of the newly introducedultrasound built-in software that could increase the diagnostic capabilityof conventional ultrasound based on the fact that breast cancer is usuallyharder than benign breast lesions. The routinely used method for classification of breast lesions accordingto tissue elasticity is the color coding as well as the strain ratio methods.Ultrasound elastography, does not only have a confirmatory diagnostictool with sono-mammography, but also can be a beneficial technique bywhich ultrasound BIRADS downgrading of benign lesions could beelicited, thus reducing the number of unnecessary breast biopsies, andconsequently improve the patients compliance .However, ultrasound elastography has some limitations, such as operatordependency, inter, intraobserver variability, and results variabilityaccording to the internal structure of lesion being evaluated. So the casesshould be evaluated as a whole regarding the history, clinical data, sonomammographicfindings, and ultrasound elastographic evaluation toattain the best diagnostic results, and to avoid false positive, and negativediagnoses.
