Most women experience breast tenderness around 45 days after menopause as their hormone levels increase. In most cases, the breasts will be swollen and painful, and the breasts will be enlarged, and the nipples and areolas will be colored, and Montgomery’s nodes will appear on the areola, which is mainly due to the increase of estrogen in the body. Clinically, breast care must be strengthened during pregnancy, and if the breast swelling and pain is unbearable, it is recommended to go to the hospital for examination to exclude the possibility of other problems. It is also recommended not to wash the breasts with conditioner, shower gel or soap while caring for the breasts to avoid localized skin dryness. During pregnancy, most women can tolerate mild swelling and pain in their breasts, which is normal. It is recommended that women have the appropriate examinations before pregnancy, and it is recommended that a breast ultrasound be done to rule out the possibility of other pathologies before planning a pregnancy.
