Breast cancer is a systemic disease, and breast lump is a local manifestation. Treatment emphasizes reasonable comprehensive treatment, including surgery, chemotherapy, radiotherapy, endocrine therapy, targeted therapy, etc.; Misconception 3: Not to pay attention to initial treatment. Don’t put a lot of hope on those remedies, and cherish the opportunity of initial diagnosis and treatment extremely; Misconception 4: Chemotherapy blindly seeks to be small. Chemotherapy can reduce the risk of breast cancer recurrence by an average of l/4 and the risk of death by l/7 .
