Breast hyperplasia nodules and breast hyperplasia are not much different; breast hyperplasia nodules are a more severe condition than simple breast hyperplasia. Based on the typical symptoms of cyclic breast swelling and pain, which worsen before menstruation and lessen or disappear after menstruation, and upon physical examination, nodular lumps of various sizes can be felt within the breast, which are tough but not hard, sometimes tender to the touch. Supplementary examinations like ultrasound show uneven low-echo areas in the hyperplastic breast, and if cysts are present, they form anechoic areas. Breast mammography shows ground-glass or cotton-wool shadows, which can be diagnosed as breast hyperplasia. However, it is important to be wary of the potential coexistence of breast hyperplasia and breast cancer. On one hand, patients with significant hyperplasia should be closely monitored; on the other hand, patients with obvious hyperplastic lumps or unclear boundaries of thickened breast tissue should undergo fine-needle aspiration biopsy of suspicious lesions to prevent misdiagnosis.
