Patients with mammary gland hyperplasia can feel foreign objects when touching, but the pain from pressing is not very obvious. Patients generally can feel multiple or single nodules with elasticity, and there is no noticeable pain when pressed. Some patients may also experience symptoms such as breast tenderness, which is usually more pronounced before menstruation and may relieve on its own after menstruation ends. Mammary gland hyperplasia is mostly a benign tumor. If the symptoms are not very noticeable, observation can be the first approach. However, if hyperplastic nodules appear, cytological puncture should be conducted, and surgery may be necessary to achieve a cure when needed.
