Critical imaging analysis of suspicious non-palpable breast lesions

Abstract

Screening programs using MMG seem to result in a general decline in breast cancer mortality and recommendations that women over the age of 40 should undergo annual screening mammography have led to an increasing number of diagnoses of non-palpable breast lesions ⁸ . The first sign of non-palpable breast cancer may be calcifications, and MMG is currently the best modality to detect microcalcifications. Furthermore, breast cancer cases that are manifested as focal asymmetric densities, also evaluated by this method, tend to be non-palpable lesions. On the other hand, excessive diagnosis of architectural distortions (distortions of the breast parenchyma without a defined mass) leads to lower mammographic specificity ^9,10 . It is important to consolidate and disseminate screening programs, still deficient in underdeveloped and developing countries, technical improvements, and adequate training of radiologists to recognize the imaging characteristics and behavior of these lesions so that MMG can be used in the diagnosis ⁷ .
