1.Pathological type: Most of them are invasive ductal carcinoma. Of course, medically speaking, there are some pathological types with relatively good prognosis, such as mucinous carcinoma, medullary carcinoma, etc. However, patients do not need to be too concerned about the pathological type, because the prognosis is closely related to many factors such as lymph node metastasis. 2.Lymph node metastasis in axilla: Lymph node metastasis is closely related to the prognosis, of course, the less the better; it is generally expressed in X/X way, for example, 1/12 means: 12 lymph nodes are cleared in the axilla, among which there is 1 metastasis. 3. Common immunohistochemical indices: 1) ER (estrogen receptor) and PR (progesterone receptor): two or one positive can be treated with endocrine therapy (two positive is better than one positive, and the stronger the positive degree, the better), theoretically: ER and PR positive patients have better prognosis than negative patients; 2) Her-2/C-erbB-2: positive as a risk factor for breast cancer prognosis. Her-2+++ (immunohistochemistry) or Her-2 amplification (Fish test) can be targeted with Herceptin; 3) Ki-67: responding to the proliferative activity of cancer cells, as one of the indicators of molecular typing of breast cancer.
