Symptoms of breast hyperplasia mainly include pain, nodules or lumps, nipple overflow and so on. 1. Pain: The first clinical symptom of breast hyperplasia is breast pain. If the pain is cyclic, it is mostly physiological, such as pain before menstruation; for non-cyclic pain, it may be due to breast disease, pharmacogenetic factors or other diseases. In addition, cyclic pain may also be due to breast disease, pharmacogenetic factors or other diseases. 2. Nodules or lumps: Patients with breast hyperplasia often develop breast nodules or lumps, including striated nodules, granular nodules. Lumps are usually small and of different shapes, while nodules are usually multiple and may involve both breasts. 3. Nipple discharge: a small number of patients will be accompanied by nipple discharge, usually colorless, yellowish or milky white pulp, and a few patients will have bloody discharge. If the symptoms of breast hyperplasia are more serious, patients must go to the hospital in time for treatment.
