Breast firmness in the fifth year of menopause may be caused by the slow degradation of breast tissue, which is a normal phenomenon. Normally, postmenopausal women may experience a rapid decrease in endogenous estrogen secretion, and the breast tissue is unable to adapt in time, leading to symptoms of breast firmness. Localized swelling and pain, nodules, etc. are also common clinical symptoms with a variety of etiologies. Rapid changes in hormone levels after menopause may lead to hormone level disorders, which may lead to blockage of the milk ducts causing mastitis, and may also lead to breast hyperplasia causing localized swelling of the breasts resulting in breast firmness. Postmenopausal women are also at high risk of breast cancer. If you experience breast firmness, it is recommended that you go to the hospital as soon as possible and under the guidance of your doctor, undergo the appropriate formal treatment.
