The survival time of patients with breast malignancy is related to tumor type, presence or absence of metastasis, metastatic site, sensitivity to treatment, tumor load, molecular typing, etc. They may survive for a long time or only a few years or even a few months. In general, early stage tumors, well differentiated, low malignancy and treatment sensitive tumors, have good prognosis and patients have slightly longer survival time, usually above 5 years. Patients with advanced stage, poorly differentiated and high malignancy, especially those with visceral metastasis, generally have a survival time of less than 3 years, and some patients have a survival time of not even more than 6 months. There are many factors affecting the treatment outcome of breast cancer, early detection, early diagnosis and early treatment are the keys to improve the survival time. With the advancement of treatment, many patients with advanced breast cancer can also achieve long-term survival. Patients with breast malignancy must actively cooperate with treatment, maintain a good state of mind, and be alert to the adverse effects of chemotherapy to minimize pain and prolong survival.
