The new molecular classification of breast cancers defines cancer sub-groups with a distinct prognosis and response to treatment. Studies on the literature deal with the imaging of each tumour sub-type. The radiologist should be familiar with them in order to adapt the care of an aggressive sub-type. In view of the current knowledge, the following have been significantly more often observed: mammographical spiculated mass with echogenic halo in luminal A sub-type; architectural distortion in luminal B sub-type; an irregular mass with indistinct margin comprising microcalcifications, with an abrupt interface in the sonography, or non-sonographic mass in the HER2 sub-type; a very hypoechogenic, lobulated mass with indistinct or microlobulated margin, with an abrupt interface, sometimes pseudo-benign, in the triple-negative sub-type.
乳腺癌的新分子分类定义了具有不同预后和治疗反应的癌症亚组。文献研究涉及每种肿瘤亚型的影像学表现。放射科医生应熟悉这些表现，以便对侵袭性亚型进行适当的治疗。基于目前的知识，以下情况更为常见：管腔A型亚型中伴有回声晕的乳腺钼靶毛刺状肿块；管腔B型亚型中的结构扭曲；HER2亚型中边界不清、包含微钙化的不规则肿块，超声检查时有突然的界面，或非超声肿块；三阴性亚型中极低回声、分叶状肿块，边界不清或呈微叶状，有突然的界面，有时呈假良性。
