After menopause, breast enlargement will generally be relieved, but endogenous estrogen secretion decreases rapidly during menopause, and the breast tissue cannot adapt to this change yet, and the response of each part of the breast to the decrease of hormones is not uniform, so breast enlargement such as breast pain, nodules or glandular thickening can exist for quite some time after menopause. If an older woman has been menopausal for several years, and her breasts have been “calm” for a long time, and suddenly new changes appear, even if they are slight, she should go to the hospital immediately and be alert to the possibility of breast cancer.
