The cure rate of intraductal breast cancer with microinvasion ranges from 80-95%. Micro-infiltration of intraductal breast cancer means that in the primary lesion, there is a slight tissue infiltration, but there is no metastasis to the surrounding tissues and lymph nodes, which is still at the early stage, and it can be treated by radical surgery, in which the lesion and the cancer cells can be eliminated, so as to achieve the cure, and the cure rate is maintained at the range of 80-95% in the clinic. In general, the cure rate of microinvasive intraductal breast cancer is still relatively high, but there is still a certain risk of recurrence, therefore, radiotherapy, chemotherapy, endocrine therapy or targeted therapy should be carried out in combination with pathological tissue examination after surgery.
