Patients with breast cancer have a 4-year history of bone metastases, and the survival time varies from patient to patient, ranging from six months to a year if the disease is complicated by significant anemia and hypoproteinemia at a later stage. In this case, systemic intravenous chemotherapy can be chosen to combine with anti-bone metastasis treatment, which can control the rate of tumor development and achieve the purpose of prolonging the patient’s survival time. Advanced breast cancer is also prone to complicate with lung metastasis and liver metastasis, and patients experience significant pain, chest tightness, palpitations, coughing with blood and pain in the upper abdomen, and also have irregular fever. The cause of breast cancer is related to the abnormal hormone level in the body, and it occurs very often in middle-aged and elderly patients. If early diagnosis and timely surgery is chosen, the survival time is very satisfactory.
