Patients with breast cancer can survive for more than 20 years after surgery if they are diagnosed early and choose surgery early. For patients who are already in the middle to late stage or progressive stage when diagnosed, effective intravenous chemotherapy or radiation therapy after surgery can lead to a survival time of more than 5 years. For early diagnosis of breast malignancy, the diagnosis is also confirmed by ultrasound or mammography, so surgery should be chosen early. After surgery, adjuvant treatment should be given to prevent recurrence as well as metastasis, which can improve the survival time of patients at an early stage. The cause of breast cancer is related to the abnormal expression of hormone levels in the body, which should be prevented in daily life.
