At what age do girls start to develop breasts?

At what age do girls start to develop breasts? Many people cannot give the correct answer to this question. In fact, this question has a very standard answer. I think it is necessary for girls to understand the knowledge about breast development. Even if they have passed the age of development, if they have a little daughter in the future, they can refer to the standards and observe the child's development in time.

Breast development in girls marks the beginning of the development of female secondary sexual characteristics and is also a signal of the onset of puberty. Under the action of sex hormones, the breasts of girls aged 9 to 11 begin to develop. First, the nipples protrude and feel like a small lump, with some swelling and pain. Later, the breasts gradually swell and the light brown areola around the nipples gradually deepens in color and increases in size. Later, the nipples become large and protruding, and the breasts become fuller. Due to the influence of many factors such as genetics, environment, nutrition, and physique, the age at which girls enter puberty varies greatly from person to person. Generally speaking, breast enlargement from the age of 8 to 14 is normal. If breasts have not developed after the age of 16, you should go to the hospital to check the cause.

Girls' breast development usually begins when their nipples start to grow, at around 9-10 years old. At 10-11 years old, breast hyperplasia occurs, forming a breast nucleus, which feels like a nodule or a small lump and is painful when pressed. At 12-13 years old, the mammary ducts and subcutaneous fat increase, the breasts gradually bulge and become elastic, and the color of the areola and nipples darkens. Mature breasts are blue spherical and located between the 3rd to 6th ribs. The nipples have an erectile function and are hard when touched, which is conducive to lactation. Girls' breast development is related to the secretion of female hormones in the body.

The breasts are located on the front chest and are the organs for feeding children.

Before puberty, there is no difference in appearance between boys' and girls' breasts. Starting from the age of 7-8, girls' body systems gradually develop.

About 2 years later, breasts begin to develop under the combined action of ovarian hormones, pituitary hormones and insulin.

The age of breast development also varies from person to person, with an average of 10.8-11.4 years old. If breasts have not developed after the age of 16, you should be alert to whether it is delayed sexual development or ovarian hypoplasia.

When girls start to develop breasts, they must not be careless about their diet, and girls should not be ashamed and feel embarrassed about breast development. This is your breast development, and you will never regret it in the future! Breasts have always been the second face of girls, and they are very important. If you accidentally develop a flat chest, no matter how beautiful your face is, it will not make up for it!
