When do girls develop breasts?

The breast is a very important part for women. It is not only one of the representative organs of women, but also they need to feed their babies through breasts after giving birth. Breasts generally develop when a girl is a girl. The time period for breast development in girls varies. Some girls begin to develop breasts when they are eight or nine years old, while others start very late. The following is a detailed introduction to when girls' breasts develop.

When girls enter puberty, the first parts of their bodies to develop are their breasts. After puberty, under the influence of estrogen in the body, girls' breasts begin to develop. At this time, in addition to the continuous development of many slender mammary ducts, a lot of fat accumulates in the breasts. Because the mammary tissue is harder and the fat tissue is softer, the breasts gradually bulge and become elastic, becoming a sign of female maturity. However, breast development conditions, such as breast size, symmetry, early or late development, and abnormal development, have become a source of worry for girls during their youth.

There is great individual variation in breast development in girls. Some girls begin to develop breasts when they are only 8 or 9 years old, while some girls do not begin to develop breasts until they are 16 years old or older. Most girls begin to develop breasts before their first menstrual period, around 9 to 14 years old. When the breasts are just beginning to develop, the mammary glands that make up the breasts and the surrounding fat tissue form a button-like bulge on the nipple and the areola around it, causing the nipple and areola to bulge and the nipple to begin to grow larger. The nipple then becomes more noticeable, gradually feels fuller, and finally develops into the shape of an adult breast. The rate at which breasts develop also varies from person to person. Some girls start developing breasts later but develop faster, while some girls develop breasts earlier but develop more slowly.

Girls whose breasts develop early are often embarrassed and troubled by this and try to hide their breasts to avoid it. They lower their heads and hunch their chests when walking, or wear tight clothes to bind their chests, which restricts the normal development of the breasts and thorax. However, the practice of breast binding will compress the breasts and nipples, leading to breast hypoplasia, which will cause difficulties in lactation and breastfeeding in the future and is also prone to breast diseases. In fact, girls who develop breasts early and have larger breasts are also affected by many factors. Some girls are fatter, so their breasts appear fuller, while some develop larger breasts due to genetic factors, nutritional conditions, climate, etc. However, breast development usually stops after a certain age. Large breasts do not have any adverse effects on the body, nor do they reflect a person's ideology, morality, and consciousness, so there is no need to worry about breast development.
