although this feature is rare, the current under standing that lobular carcinoma in situ is a marker needs to be revised.

screening picks up more cases of ductal carcinoma in situ (dcis) - cancer in cells lining the milk ducts that has not spread - than would normally be found because it is often symptomless.

做乳腺癌筛选的好处是能够使女性更早地发现是否已患乳腺导管管内原位癌（dcis，是一种肿瘤性导管内病变其特征是上皮细胞增生显着细胞明显异型 有发展为乳腺浸润癌的倾向），因为管内原位癌的发生通常是没有征兆的。
