The pathological findings of breast cancer patients after surgery are important clinical data that guide us in the comprehensive treatment after surgery. Many patients have a lot of headache about the complicated and obscure specialized vocabulary in it, not knowing what they all mean and which are the important information they need to remember for their future visits and follow-ups. Here we will briefly introduce: there are 3 main parts of information in pathology results. The first part is the specific staging of breast cancer, such as whether it is ductal or lobular, and the histological grading (grade 1 to 3); the second part is the axillary lymph node situation (for example, 1/15 means that 15 lymph nodes are detected in the axilla and one of them has metastasis; 0/16 means that there is no metastasis in all 16 lymph nodes); the third part is the specific immunohistochemical staining results of breast cancer, which is composed of many English words and The third part is the specific immunohistochemical staining results for breast cancer, which are composed of many English words and plus and minus signs, which involve a lot of expertise. As a patient, it is good to remember 3 of the most important results (ER estrogen receptor, PR progesterone receptor, C-erbB2/Her2 human epidermal-like growth factor receptor 2). Remembering the name of the cancer, the histological grade, the number of lymph nodes and whether these three receptors are negative or positive will give the doctor very useful information.
