A lump in the breast without painful symptoms is not excluded from malignant tumor of the breast. Especially for middle-aged and elderly female patients, if the surface of the lesion is not smooth and the boundaries of the adjacent tissues are not clear, or if it is combined with orange peel-like changes of the breast skin, malignant tumor of the breast is highly suspected and the cause of occurrence is related to the abnormal expression of hormone levels in the body, and surgery should be chosen in time to remove the lesion. If necessary, radical excision surgery is also required. After surgery, a combination of radiation therapy, intravenous chemotherapy, and endocrine therapy is also required. In addition, there are some patients with benign breast diseases, such as lipomas of the breast or fibroadenomas of the breast, which occur in many young people. If the lesion grows gradually, surgical excision may be an option.
