Objective：Breast cancer is the most common cancer in women，and its incidence is the highest among all female cancers worldwide. About 5%-10% of women were newly diagnosed with distant metastatic breast cancer at the time of their initial diagnosis. Stage Ⅳ breast cancer is an incurable disease，and its treatment is mainly aimed at improving the quality of life and prolonging the life of patients. At present，stage Ⅳ breast cancer is still treated by an individualized treatment program based on systemic therapy. There is no clear conclusion on whether the primary lesion of stage Ⅳ breast cancer needs local surgical treatment. This article will review the local treatment of stage Ⅳ breast cancer.
