What tests are used for screening for breast cancer?

Radiologic: The best screening procedure for breast cancer is breast palpation. To pick up the earliest lesions, mammography is the best procedure with improved digital and 3D formats. This is followed by sonography to define a localized site in thickened breast tissue and tell whether a lesion has fluid. For a more detailed study, MRI of the breast can detect many lesions not seen on mammo.
