Breast cancer with cancer embolism needs to be removed as soon as possible through comprehensive treatment such as surgery, radiotherapy, chemotherapy and targeted therapy, etc. Drugs should be applied under doctor’s guidance. 1. Surgery: if there is no distant metastasis and spread of malignant tissue, surgery can be considered to remove the diseased tissue in order to achieve the goal of curing the disease. 2. Radiotherapy: if the diseased tissue cannot be completely removed by surgical treatment, radiotherapy can be used after surgery to kill the remaining malignant cells in the body. 3. Chemotherapy: the presence of cancer embolus in breast cancer indicates that there are distant metastases. After surgery, it is necessary to fully evaluate the patient’s condition and cooperate with doctors to receive chemotherapy to inhibit the growth and reproduction of malignant cells as much as possible, so as to prolong the patient’s survival time. Commonly used chemotherapy drugs include epothilone, cyclophosphamide, paclitaxel and so on. 4. Targeted therapy: after breast cancer surgery, doctors will send the tumor specimen to the pathology department for pathological examination. In the pathological examination report, the more common ones are estrogen receptor, progesterone receptor and HER-2 index. If HER-2 is found to be positive, the patient is recommended to undergo targeted therapy. It is recommended to go to the Breast Surgery Department of the hospital as soon as possible, and receive treatment under the guidance of a specialized doctor, and the drugs should be applied under the guidance of the doctor.
