Most pregnant women experience changes in their breast tissue. Breast lump pregnancy is usually influenced by three hormones, namely estrogen, progesterone, and prolactin. Breast lump pregnancy is usually caused by the increased levels in the amount of these hormones.
Estrogen come in three forms, namely estradiol, estriol, and estrone. However, estradiol is believed to be the one which is majorly responsible for the development of breast lump pregnancy. Estrogen is produced by the ovaries and later on by the placenta. It likewise triggers the growth of the uterus, promotes increased blood circulation, and activates other hormones such as progesterone.
Progesterone, on the other hand, basically causes the mammary glands to increase in size. And just like estrogen, it is produced by the ovaries and stimulates the formation of breast lump pregnancy. Progesterone is also responsible for other pregnancy symptoms such as breast tenderness, abdominal bloating and leg edema.
During late pregnancy, another hormone contributes to the development of breast lump pregnancy. Aside from the increased levels of estrogen and progesterone, the hormone prolactin likewise becomes active after it is secreted by the pituitary gland to stimulate the production of milk. During the last trimester of pregnancy, the breast glands that are responsible for the production of milk swell and become bigger; thus, this makes the breasts lumpier than before.
There are a number of doctors who ignore a breast lump pregnancy because such occurrence is typically normal and thus, does not call for any immediate treatment. It is not a wise move, however, to reassure any pregnant woman that any breast lump pregnancy that she identifies is unimportant. Research has shown in 2009 that the number of breast cancer cases in Swedish women who are pregnant actually doubled from 1963 to 2002. It is now thought that approximately seven to fifteen percent of breast cancers occur in those who are pregnant. In addition, more cases of breast cancer are detected while a woman is pregnant than when a woman is not pregnant. With that said, it is very important for all women, pregnant or not, to visit a doctor when she discovers a breast lump so that cancer can be easily ruled out.
