What is macromastia

summary

Macromastia, also known as breast hypertrophy, macromastia or macromastia, refers to the excessive development of female breast, hyperplasia of gland and fat containing connective tissue, abnormal volume, and obvious imbalance with the body. Can occur chest pressure, chronic mastitis, pain, shoulder pain and heavy skin erosion under the breast and so on. Macromastia is more common in adolescent girls or young women, often occurs on both sides, occasionally limited to one side. Breast enlargement is caused by abnormal sensitivity of gland and adipose connective tissue to estrogen. What is macromastia? Let's talk about it.

What is macromastia

First, the etiology and pathogenesis are not very clear. Some people think that it is related to the excessive secretion of estrogen and the excessive proliferation caused by the special sensitivity of target cells in breast tissue to estrogen stimulation. Some people think that it may be related to some unknown genetic factors in breast tissue, such as gene abnormality.

Second: the gross shape of the breast hypertrophy can be flat navel, knee, weight of each side can reach 5 ~ 10kg, nipple depression, epidermal varicose veins, soft texture, sometimes can touch the size of nodules. On the section, there are greyish red hyperplasia of breast tissue, light yellow, greyish white hyperplasia of fat and fibrous tissue.

Third: histologically, the breast is mainly composed of hyperplastic glands, fat and fibrous tissue. There were small ducts with few branches and lobules occasionally. The epithelial cells of ducts proliferated in papillary structure, and secretory vacuoles were found in the cytoplasm of epithelial cells. It has been reported that the development of papillary ductal epithelial hyperplasia can lead to atypical hyperplasia, and a few (1% - 2%) can develop into breast cancer.

matters needing attention

In recent years, the disease has appeared a trend of younger, even 12-year-old girls suffering from macromastia. This makes many women very worried, and also makes many sick women feel inferior. In fact, we do not need to do so, as long as the understanding of the etiology, to active treatment or can have a normal breast.
