A woman's breasts change during pregnancy to prepare them for breastfeeding a baby. Normal changes include: Tenderness of the nipple or breast; An increase in breast size over the course of the pregnancy; Changes in the color or size of the nipples and areola; More pronounced appearance of Montgomery's tubercles (bumps on the areola)
During pregnancy, pronounced breast growth and maturation occurs in preparation of lactation and breastfeeding. [20] [29] [30] Estrogen and progesterone levels increase dramatically, [20] reaching levels by late pregnancy that are several hundred-fold higher than usual menstrual cycle levels. [31]
High levels of prolactin during pregnancy and breastfeeding also increase insulin resistance, increase growth factor levels (IGF-1) and modify lipid metabolism in preparation for breastfeeding. During lactation, prolactin is the main factor maintaining tight junctions of the ductal epithelium and regulating milk production through osmotic balance.

The effects of mildly elevated levels of prolactin are much more variable, in women, substantially increasing or decreasing estrogen levels. Prolactin is sometimes classified as a gonadotropin [ 17 ] although in humans it has only a weak luteotropic effect while the effect of suppressing classical gonadotropic hormones is more important. [ 18 ]
Breast tenderness during pregnancy is common, especially during the first trimester. By mid-pregnancy, the breast is physiologically capable of lactation and some women can express colostrum, a form of breast milk. [57] Pregnancy causes elevated levels of the hormone prolactin, which has a key role in the
