Abstract:

Mucinous cancer of the breast is generally recognized as a kind of invasive carcinoma with indolent biological behavior and relatively good prognosis. But in recent years a micropapillary pattern has been found in this kind of cancer with a morphology similar to invasive micropapillary carcinoma. The biological behavior of this subtype is more likely to lymph node metastasis and has a poor prognosis. However， the understanding about it in clinic is far from enough. In this review， the clinical characteristics， prognosis and research progress are depicted， so that people will have a clearer understanding on this subtype of breast cancer.
