What is breast development like? Little girls, please watch carefully.

Breast development is a sign that women are beginning to mature. During the process of breast development, the girl's body will show a series of reactions. The most obvious is that the mammary glands gradually bulge, and then slowly grow to form breasts. Let's learn more about it below.

1. The main component of a girl's breasts is the mammary gland, which is firm and elastic. As age increases, the fat content gradually increases, and the breasts appear slightly sagging and mature. It takes about four or five years for a girl's breasts to develop and mature. In Chinese medicine, breast development is divided into four degrees:

In the first degree, the breasts are flat and have not yet started to develop.

Second, the nipple and areola appear as bud-like protrusions.

The third degree: the breast is slightly raised, and the nipple and areola protrude on the breast like a small hill.

Fourth degree: The mammary glands swell significantly, the nipples protrude, and they develop into mature breasts.

2. The early or late development of female breasts is affected by factors such as race, genetics, nutrition, region, cultural status and living habits. There are huge differences in the early or late development of breasts. Some women begin to develop at the age of 13 and are still not fully developed at the age of 20. Some women may even be in the third degree until they become pregnant and give birth. Generally speaking, female breast development occurs between the ages of 11 and 15. If it has not developed by the age of 15, you need to be alert. If it has not developed after the age of 18, you need to consider whether there is a disease.

3. The five stages of breast development: Stage I: Before puberty, the breasts have not yet developed. Stage II: In the early stages of breast development, the breast bud under the nipple begins to grow and appears as a distinct dome-shaped protrusion. Stage III: The breasts become round and shaped like adults, but are still relatively small. Stage IV: The breasts grow rapidly, and the nipples and areola protrude forward in the shape of small balls. Stage V: Normal adult breasts are formed, and the small balls of the nipple and areola merge into the round shape of the breasts.
