The 5-year survival rate of breast cancer is high and can reach more than 70% with timely and effective treatment in the middle stage of the disease. If some patients have good treatment effect and good recovery after surgery, their life expectancy after surgery can even reach the normal healthy life expectancy. Therefore, timely and effective surgery and radiotherapy can effectively prolong the survival of breast cancer patients. However, the life expectancy of breast cancer patients after medium-term chemotherapy is also related to the type of pathology, individual physique and the effect of chemotherapy. If the female patients have better physical condition themselves, and the sensitivity of chemotherapy drugs is higher, and the pathology type is good, the postoperative survival and survival rate are higher. However, for weaker or older women with triple-negative breast cancer, the survival period is relatively shorter. It is recommended that women should undergo surgery and radiotherapy or endocrine therapy or targeted therapy as early as possible after the emergence of breast cancer, which can effectively prolong the survival period.
