Explain why breast swelling and pain occur before menstruation

　　Relevant experts say that before menstruation, breasts feel distended pain , sometimes you can feel the painful hardness. This is because the glands of the breast are connected with the Uterus Like the endometrium, changes in the premenstrual hyperplasia phase and postmenstrual recovery phase will occur with changes in the menstrual cycle.

　　The premenstrual proliferative period is 7-10 days before menstruation. At this time, due to the increased concentration of androgens and progesterone, hyperactive antidiuretic hormone, and increased secretion of aldosterone, the breast ducts expand, epithelial cells proliferate and enlarge, and the matrix edema around the breast ducts causes compression symptoms and pain. At the same time, immature fibers in the mammary gland increase, lymphocytes infiltrate, the breasts enlarge, and you will feel pain and discomfort. The menstrual recovery period refers to the period after menstruation, when the secretion of estrogen, progesterone and antidiuretic hormone in the body decreases, the milk ducts become smaller, the epithelial cells shrink, the immature breast fibers decrease, and the symptoms of breast tenderness disappear.

　　It can be said that if you feel breast swelling and pain in the early stages of menstruation, it reminds you: menstruation is about to "come". Some people compare the period before menstruation to "high tide", and the breasts will be swollen and painful. It is appropriate that menstruation is followed by the "ebb" period when breast swelling and pain decrease or disappear.

Women’s emotions can also easily cause hormones in the body and can also cause breast cancer disease , so if such a situation occurs in the early period of menstruation, it should be treated correctly.
