The pathological result of breast cancer puncture depends on whether the cancer is invasive or non-invasive, if non-invasive, it is also known as carcinoma in situ. In addition to the pathological type of the tumor, immunohistochemistry results are also generally required. Immunohistochemistry results mainly depend on whether the estrogen receptor and progesterone receptor are positive or negative, and if they are positive, endocrine medication is required to suppress estrogen secretion in the body. If Her-2 is strongly positive, treatment with Herceptin-targeted drugs is also required. It is also necessary to look at the Ki67 index. If this index is particularly high, it indicates that the tumor cells are growing more actively and are prone to cause distant metastasis.
