Breast adenopathy is an early manifestation of structural malformation of the breast, divided into 3 stages: lobular hyperplasia, fibroadenopathy and sclerosing adenopathy, most of which will not become cancerous, but in a few cases, it may develop into cancer, and the time can vary from several years to several decades. Breast adenopathy may be related to endocrine disorders and mental factors. Early stage patients can be treated conservatively with regular follow-up and mammography or mammogram every six months. Once cancer is suspected, timely surgical removal and pathological examination are required. If the pathological examination confirms the diagnosis of breast cancer, patients should consider modified radical mastectomy or radical mastectomy with breast preservation, and after the surgery, there is also a combination of chemotherapy, radiotherapy, endocrine therapy and other treatments. Patients with breast adenopathy are advised to develop good living habits, avoid spicy and stimulating foods, stay away from smoking and alcohol, avoid staying up late and overworking, and maintain a good state of mind.
