1, breast development process

1. Early childhood

At birth, the nipple is sunken, and the areola is also formed, which contains a ductal acinar system with 15~20 leaves, and its acinar contains a small amount of colostrum (due to the stimulation of maternal estrogen, the fetal mammary gland secretes liquid. However, it will be discharged from the nipple within one week after birth, and it will last for three to four weeks after delivery, and the acinar tissue will quickly degenerate into ductal tissue. In infancy and childhood, breasts rarely develop.

2. adolescence

When girls are ten to twelve years old, the hypothalamus begins to secrete gonadotropin, which leads to the secretion of gonadotropin by pituitary gland, which in turn stimulates the secretion of estrogen and lutein by ovaries. Estrogen stimulates mammary duct development, while progesterone stimulates acinar development, resulting in rapid growth of adolescent mammary tissue.

Generally, the breast development in adolescence is divided into five stages.

A. the first stage: nipple protrusion.

B. The second stage: from the age of ten to twelve, the breasts begin to develop, the areola becomes bigger, and the breasts form hills.

C. Stage III: About thirteen to fourteen years old, nipples and breasts continue to develop.

D. Stage 4: At the age of fourteen to fifteen, the areola and nipple begin to bulge, and the breasts gradually become spherical.

E. Stage 5: After the age of fifteen, the breasts gradually mature and finalize the design.

In the early pregnancy, the blood vessels in the breast increase and the superficial veins become obvious, usually accompanied by pain and itching. In addition, the nipple of areola will become bigger and darker. The change of breast tissue is the proliferation of duct molecules and acinar cells, which leads to the growth and branching of ducts, which can reach several times that of non-pregnancy

From the second trimester of pregnancy, the proliferation of acinar cells gradually decreased and replaced by cell differentiation. From the second trimester of pregnancy, acinar cells gradually become monolayer secretory cells, so in the second trimester of pregnancy, a small amount of yellowish liquid can be seen in the acinar cavity, which is called colostrum. Breast swelling continues throughout pregnancy, because cells have been differentiating and developing, and the secretion of acinar cells has been increasing.
