Is it normal for girls to have big breasts and small breasts? Is it normal for girls to have asymmetrical breasts?

A girl's breast is an organ rich in fat, and it is also a place where women breastfeed. Girl's breast is very fragile, because it is the nutrition channel of girl's breast, so once the breast tissue has problems, it will affect the health of girl's breast, and the amount of fat is related to the size of girl's breast. So, is it normal for girls to have big breasts and small breasts? Is breast asymmetry normal?

1, causes of breast asymmetry

There is indeed a difference between a woman's mature breasts. Generally, the left side is larger than the right side, but the vision is difficult to distinguish, and it can only be found by careful measurement. So it's not pathological. Experts explain this. The inconsistent size of the left and right breasts has no effect on fertility and sexual function, and it is not harmful to health.

It is normal for many people to have different breast development rates around adolescence. When they mature, both breasts will be the same size. But in adulthood, if the size of the breasts on both sides is very different, you will go to the clinic. It is worth noting that due to improper breastfeeding habits, one breast droops and the breasts are asymmetrical.

Why do women's breasts vary in size?

Young women's breasts, one big and one small, are caused by many reasons, both physiological and pathological; There are temporary and permanent ones. If it is purely physiological, as it matures, the breasts on both sides will gradually become symmetrical.

Congenital nipple depression or affecting sexual function

Clinically, many girls have nipple depression, which also belongs to breast dysplasia. However, nipple depression is very harmful: it hinders breast fitness; Affect breast health. Because the nipple is depressed, breastfeeding is often forcibly pulled out, which is easy to be damaged, ruptured and bleeding, which can cause nipple and even the whole breast infection and eventually mastitis.

In addition, because nipple is a particularly important sexual sensitive point for women, many women's sexual functions are realized through nipple stimulation. Once the nipple is sunken, it is difficult to exert effective sexual stimulation and even affect the man's sexual function.

The formation of congenital nipple depression is mainly due to the fact that the fibers of the nipple are weaker than normal, the nipple is close to the breast, and the mammary duct of the gland is short and underdeveloped. This can happen in one or both breasts, and the probability of both breasts is 25%. During the embryonic development of the breast, at the eighth month, the epithelium of the breast began to sink, forming a shallow concave, which is called mammary gland concave. If the development is normal, the interstitial hyperplasia around the mammary pits will lead to the gradual disappearance of the mammary pits, protruding from the body surface and forming nipples. If the mesodermal mesenchymal does not grow into the nipple area in the later stage of embryonic development, resulting in the nipple not disappearing completely, but being depressed instead of protruding, a congenital nipple depression will be formed. Generally, a slight nipple depression can be left untreated, but a serious depression will make the nipple shrink in the breast, which is easy to infect and affect the normal lactation after delivery, so it is necessary to treat it as soon as possible.

Many acquired nipple depressions are caused by women's own carelessness. The most common causes of acquired nipple depressions are as follows:

1, improper use of bra.

Bras that are too small, too tight and used too early will cause nipple depression. In addition, according to research, nipple depression is also related to heredity. It has been observed that mothers and grandmothers with sunken nipples are more likely to suffer from sunken nipples in the next generation than normal people.

The clothes are too tight.

Especially in the breast development period, it is very easy to cause nipple depression.

Friendly reminder: If a woman finds any abnormality in her breasts, she must go to the procuratorate to find out the reason.

2. Standard breast shape

First, plump, symmetrical, flexible and elastic.

Second, the shape is tall and straight, hemispherical.

3. Hemisphere: the height of the thoracic axis is 3-5cm, which is about 1/2 of the diameter of the thoracic base.

Fourth, the breast position is high, between the second and sixth ribs, and the nipple is located between the fourth rib.

5. The distance between the two nipples is more than 20cm, the diameter of the basal surface of the breast is 10- 12cm, and the axis of the breast (the height from the basal surface to the nipple) is 5-6cm.

6. Bowl shape: the concentricity of the breast is 2-3cm, which is less than 1/2 of the diameter of the breast base. It belongs to a relatively flat breast.

7. Conical shape: 1/2 with the height of the chest axis greater than 6cm and the diameter of the chest base.

Eight, upright type: the breast is tense and elastic, and the chest axis is almost 90 degrees from the chest wall.

Nine, hanging type: the milk axis is obviously downward, soft and elastic. The standard of breast bodybuilding includes many factors such as breast shape, breast skin texture and nipple shape.

Ten, downward type: the milk axis is slightly downward, soft and elastic.
