Triple negative breast cancer is not always the most serious. The molecular phenotype of breast cancer is only one of the factors that affect the prognosis, other than the size of the primary tumor and the presence of metastases from other sites at the time of detection. If it is a triple-positive breast cancer, but it is found to have distant metastasis, the treatment effect is not as good as those of early triple-negative breast cancer. Triple-negative breast cancer refers to estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2), all three of which are negative. However, triple-negative breast cancer is more sensitive to chemotherapy. If early surgery and postoperative adjuvant chemotherapy are combined, some of them can achieve the effect of radical cure.
