The survival period of breast cancer patients with liver metastasis may be more than 5 years, which is related to the treatment method, specific condition, psychological factors, etc. Generally speaking, the earlier the detection, the earlier the diagnosis and the earlier the treatment, the lower the impact on the life expectancy of the patients, and it is recommended that the patients should have regular treatment as early as possible. Clinically, “5-year survival rate” is often used to assess the survival of tumor patients. According to the statistics of International Cancer Organization, the 5-year relative survival rate of breast cancer patients is 89.9%, among which the 5-year survival rate of in situ cancer is 98.8%, the 5-year survival rate of early invasive carcinoma is 85.5%, and the 5-year survival rate of distant metastasis of invasive carcinoma is only 27.4%. The 5-year survival rate for distant metastasis of invasive cancer is only 27.4%. Breast cancer is a phenomenon in which breast epithelial cells proliferate out of control under the action of various carcinogenic factors. Breast cancer adopts the principle of precise and comprehensive treatment, and psychological support, chemotherapy and other treatments are combined according to the biological behavior of the tumor and the patient’s physical condition, in order to improve the therapeutic effect and the patient’s quality of life. It is recommended that when breast cancer patients develop liver metastasis, they should be treated under the guidance of doctors in a timely manner, and the earlier the treatment is carried out, the less impact it will have on the life expectancy of the patients, which can effectively prolong the survival period of the patients.
