Eight times of chemotherapy after breast cancer surgery does not indicate that the patient’s condition is very serious, but is usually some conventional chemotherapy number. If a patient is determined to need chemotherapy after surgery through pathological examination, usually eight sessions of chemotherapy are required, that is, eight courses of chemotherapy, and the overall time is about six months, usually using a three-week course of treatment. In the process of breast cancer treatment, patients may have some adverse reactions, such as nausea, vomiting or bone marrow suppression, which means lowered white blood cells and lowered granulocytes, and so on, and need to use some drugs to treat the symptoms or relieve some adverse reactions in chemotherapy. In addition, it is recommended that patients should come to the hospital for regular follow-up after chemotherapy is completed.
