如图所示：当基底膜完整时，我们称“原位癌”，因为肿瘤还局限在上皮内。
If the basement membrane is still intact, as shown here, then the process is called "carcinoma in situ" because the carcinoma is still confined to the epithelium.
该过程可以称为癌转移，即癌细胞从原位癌转移到身体的其它部位形成继发癌。
In a process called metastasis, these cells are transmitted from the primary tumor to other locations in the body, where they form secondary, cancerous growths.

导管原位癌(DCIS)的高发病率和治疗多样化促使人们探究各种治疗的比较效应。
Background the high incidence of ductal carcinoma in situ (DCIS) and variations in its treatment motivate inquiry into the comparative effectiveness of treatment options.
一项新的研究显示，在原位癌周边的肝组织中，特定的基因表达特征可以预测这种远期复发。
A new study shows that a certain gene-expression signature found in the liver tissue adjacent to the primary tumor can predict such a late recurrence.
目前医学界不能确定管内原位癌最佳的治疗方式，但可以肯定的是有一些可能永远都不会成为威胁生命的癌细胞。
Doctors are uncertain about the best way to treat them and accept some would never become life-threatening cancers.
因为这种肿瘤非正常生长通常并不显示出长期的风险，一些专家质疑原位导管癌(DCIS)是否需要治疗。
