At what age do girls usually develop breasts?

All women will go through puberty, and the time when girls enter puberty varies depending on their own qualities. A girl's breasts are the most obvious sign of her development. In the early stages of development, the breasts will feel a slight pain. Some children feel scared and fearful. In fact, as parents, we just need to explain to our children that it is just a normal physiological phenomenon. So at what age do girls usually develop breasts? Let’s look at the following introduction with this question in mind.

1. Development time

Breast development begins between the ages of 8 and 12. Initially, the mammary glands that make up the breasts and the surrounding protective fat tissue form a button-like bulge in the breasts and the surrounding areola (breast bud stage). After that, the nipples begin to grow larger, the areola gradually expands, and the color of the breasts and areola gradually deepens. Around the age of 14 to 15, breast development becomes more obvious and the breasts become noticeably raised. At the age of 16 or 17, the breasts are full, with clear lines, slightly sunken areolas, and large and prominent nipples. At around the age of 18 or 20, the size and shape of the breasts are that of an adult woman (breast stage). However, the girl's breasts cannot secrete milk at this time, and it will take until she gives birth.

2. Normal development stage

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.

3. Symptoms of precocious puberty

Precocious puberty in girls is manifested by the development of female sexual characteristics, such as breast growth, widening of the hips, growth of pubic and axillary hair, development of reproductive organs and the onset of menstruation. Symptoms of precocious puberty in boys include the growth of pubic hair, armpit hair, beard and Adam's apple, deepening of the voice, enlargement of the penis and testicles, and nocturnal emission. These are all homosexual precocious puberty. If a girl develops male sexual characteristics prematurely as she grows up, such as growing a beard, a long Adam's apple, a deepening voice, an enlarged clitoris, etc., this is called heterosexual precocious puberty, and is an abnormal phenomenon that requires prompt medical treatment.

Precocious puberty occurs more frequently in girls than in boys, with the ratio of girls to boys being 8:1. The cause of precocious puberty is unknown in 80% of girls and 40% of boys. Central nervous system damage, hypothyroidism and fibrous dysplasia of bone can all cause precocious puberty.

However, it should be noted that due to the continuous improvement of modern living standards and the increased intake of nutritional supplements, the age at which children enter puberty and reach sexual maturity has a tendency to be gradually advanced worldwide. Therefore, it is sometimes difficult to draw an absolute dividing line in age between normal sexual maturity and precocious puberty in children.

4. What to do about precocious puberty

It should be pointed out that the earlier the sexual maturity, the faster the progression, and the greater the possibility of tumors. Parents need to pay attention to this and not assume that if a child develops early, he or she will become an adult early. In addition to actively examining and treating children with precocious puberty, appropriate sex education should be implemented to let them understand that sexual maturity is a natural phenomenon. At the same time, they should understand that girls with true precocious puberty already have fertility and need to be careful to prevent the possibility of conception.

The above is all the relevant information about the age at which girls usually develop breasts. The development of a girl's breasts indicates that she has slowly entered puberty. At this time, children seem to understand many things, so parents should give their children more patient education and guidance to help them have a correct understanding of the physical and psychological changes during puberty. So that children can grow up healthily.
