Triple negative breast cancer is more difficult to cure. Because patients with triple-negative breast cancer are negative for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2, of which estrogen receptor and progesterone receptor are insensitive to endocrine therapy, and human epidermal growth factor receptor 2 is also insensitive to molecular targeting therapy in conjunction with surgery, the prognosis of triple-negative breast cancer is poor, and it is difficult to cure. At present, triple-negative breast cancer can only be treated by chemical drugs such as doxorubicin, epirubicin and docetaxel. It is suggested that patients should regularize their work and rest time, adjust the rhythm of life, maintain a relaxed mood, reduce mental or psychological stress factors, and keep a light diet and pay attention to balanced nutrition during the period of medication. All of the above drugs should be used under the guidance of a professional doctor, to avoid the adverse effects of self-medication.
