Metastatic foci to the breast from a wide variety of primary malignancies appear on mammograms as circumscribed spheroid shadows with only slightly irregular margins, and without evidence of microcalcifications, spiculations, or other signs of desmoplastic response that characterize many primary scirrhous carcinomas. In the cases studied, there was close correlation between the size of the metastatic lesion at palpation and mammography, a feature also characteristic of the well-circumscribed carcinomas. This is not the case with most scirrhous breast carcinomas, whose associated desmoplastic reaction results in an apparent larger size by palpation than observed on mammography.
来自各种原发性恶性肿瘤的乳腺转移灶在乳房X线照片上表现为边界清晰的类圆形阴影，边缘仅有轻微不规则，且无微钙化、毛刺或其他许多原发性硬癌所特有的促纤维增生反应迹象。在所研究的病例中，触诊时转移病灶的大小与乳房X线照片上的大小密切相关，这也是边界清晰的癌的一个特征。大多数乳腺硬癌并非如此，其相关的促纤维增生反应导致触诊时的大小明显大于乳房X线照片上观察到的大小。
