Breast nodules are cystic hyperplasia of the breast, a non-neoplastic condition that is most common in women of childbearing age. Symptoms of breast nodules are mainly characterized by periodic pain in the breast. The treatment of breast nodules cannot be generalized, and a detailed diagnosis and treatment should be determined according to the patient’s condition. Nowadays, there are two types of treatment, one is surgical removal and the other is observation and follow-up. If the following situations occur, timely surgery is recommended: first, the lump grows too fast. In this case, the chances of tumor malignancy increase, delayed treatment time, the lump increases significantly, and the surgical trauma is bound to increase. Second, patients who are preparing for pregnancy. Because pregnancy can stimulate the rapid growth of the tumor, it is better to remove it before pregnancy. Third, menopause. Because the incidence of breast cancer increases at this time, it is recommended to remove the breast lump early.
