Estrogen, Progesterone, And Prolactin Can Cause Breast Lump Pregnancy

Breast changes are usually expected in women who are pregnant. Estrogen, progesterone, and prolactin are the main hormones responsible for the development of breast lump pregnancy. The hormonal fluctuations related to pregnancy is normally the reason for the development of lumps in the breast.

Estrogen come in three forms, namely estradiol, estriol, and estrone. It is estradiol, however, which is considered the main hormone that influence the formation of breast lump pregnancy. Estrogen is secreted mainly by the ovaries and the placenta. It likewise makes the placenta grow, increases the amount of circulating blood, and regulates the production of other hormones like progesterone.

Progesterone, on the other hand, is responsible for the development of the mammary glands. It is also produced by the cells of the ovaries and is a major influence to the development 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.

Some doctors pay not so much attention to a breast lump pregnancy because breast lumps are common in pregnant women; thus, do not demand any immediate concern. It is not a good idea, however, to reassure a woman that any breast lump pregnancy that she feels is insignificant. In a study that was conducted in 2009, it was revealed that breast cancer occurrence in pregnant Swedish women has doubled from 1963 to 2002. It is now thought that approximately seven to fifteen percent of breast cancers occur in those who are pregnant. Furthermore, an increasing number of breast cancer cases are being identified during pregnancy. That being said, any lump, regardless of whether a woman is pregnant or not, should be reported to a physician to rule out cancer.
