How the breasts grow. Signs of breast growth in girls

In the life of every teenage girl, one of the most important stages is breast development. During this period, hormonal changes occur in the body, which indicate puberty. Pediatricians, gynecologists and mammologists indicate that the intensity of the development of the mammary glands in girls it is necessary to control in order to timely identify possible violations in the work of the endocrine and reproductive systems.

Sexual maturity is necessarily preceded by a period of two years of active growth. Every mother should know the signs of breast growth in girls in order not only to control the development of her daughter, but also to choose the right bra for her in a timely manner.

At what age does girls' breasts begin to grow?

At 6 weeks gestation, the embryo forms mammary glands from the exoderm. Already at 3-4 months in the gestating fetus, milk ducts, nipples and glandular tissue are formed. During the first 3 years of life, the child is actively growing. If growth retardation is noted, then the nipple may be flat or inverted. In medical practice, abnormal cases of the absence of nipples in children have been recorded.

The intensity of breast development depends on the girl's hormonal levels. Breasts begin to undergo significant changes from the age of 10. During this period, seals are felt around the nipple. The nipple is pulled forward, the areola appears. Sometimes girls complain of chest pain, but in 99% of cases this symptom does not indicate the presence of abnormalities in the development of the mammary gland. By the age of 17, the breasts are practically formed. At the same time, in girls, the areolas have a pink tint, and not brown, as in adult women.

Signs of breast growth in girls are more actively manifested in puberty. The mammary glands produce a special lubricant for the areolas and nipples to prevent the skin from drying out. In some cases, hairs may appear around the areolas, which is quite normal. If there is excessive body hair growth, then it is recommended to seek advice from an endocrinologist so that a specialist checks the level of hormones in the girl's body. The size of the nipple, its shape and the color of the areola do not affect the quality of lactation in the future.

In the scientific community, the growth of the mammary glands is called "thelarche". Breast shape depends a lot on physique, nationality and genetic factors. The condition of the mammary gland is affected by hormonal surges. For example, 3-4 days before the onset of menstruation, the breasts become more sensitive, increase in volume and can be uncomfortable.

Breast development stages

Signs of breast growth in girls directly depend on the stage at which the development of the mammary glands is. Gynecologists and mammologists say that the breast takes 10 years to form. In total, each girl goes through 4 stages of breast development. At the same time, scientists have proven that the breast changes at different stages of life, but the peak of its growth occurs in the first 16-18 years of a girl's life. After the onset of menstruation, the formation of the skeleton and the figure of the girl takes place. This is a natural process that is seen as one of the main signs of puberty.

From birth to 10 years

From the first days of life until the age of 10, the child is at the stage of progression. In girls, swelling of the nipples, slight reddening of the skin around the areola is noted.

At this stage, the girl's mammary glands have not yet increased in size, since the growing body is only preparing for the upcoming changes.

The onset of puberty

Active breast formation occurs between the ages of 10 and 12. This stage of development of the mammary glands is characterized by the onset of painful sensations. The child may complain of itching and burning in the nipple area. All symptoms go away on their own, so there is no need to take pain relievers.

At the initial stage of puberty, the nipples acquire a rounded shape, and the breasts become softer, more elastic. At the same time, there are no significant visual changes, since the mammary glands are just beginning to increase in volume.

Puberty

In 95% of cases, at the age of 13-14, girls begin their periods for the first time. It is during this period that painful sensations in the chest can disturb, and the areolas around the nipples become darker. The chest visually becomes larger. The girl's condition must be monitored, since the hormonal balance in her body is subject to sudden surges. An irregular menstrual cycle is normal.

Completion of the period of sexual development

The mammary glands grow most actively in the period from 14 to 15-16 years. At the final stage of sexual development, all the necessary reproductive functions are formed. A young girl may be disturbed by squeezing in the bust, as the ducts grow rapidly in the mammary glands.

Doctors cannot say for sure to what age breasts grow. Each organism is individual, which is why physiological processes proceed with different intensities. Gynecologists say that puberty and the formation of mammary glands occurs before the age of 20.

Signs of growth, features and possible variations in symptoms

During the period of active breast growth, girls show symptoms characteristic of this physiological process.

You can recognize the rapid development of the mammary glands if you pay attention to the following factors:

• In the area of ​​the nipples, the volume of tissues is significantly increased, which is easy to determine during palpation of the breast.
• The girl is worried about painful sensations in the mammary glands. If the uncomfortable symptoms intensify, then it is recommended to visit a pediatric gynecologist to rule out the likelihood of developing pathologies.
• The nipples grow in size and become more sensitive.
• Multiple hairs can be seen on the chest.
• Multiple tubercles appear on the areolas, thanks to which the glands will moisturize the nipples, which is extremely important in everyday life and during breastfeeding.
• Areolas take on a more languid shade.
• With rapid breast augmentation, stretch marks (stretch marks) may appear. In this situation, gynecologists recommend using a special moisturizer.
• In the area of ​​the nipples, itching and burning periodically occur.
• One breast may become slightly larger than the other.

Signs of breast growth initially scare many girls, since it is difficult for them to understand the natural processes taking place in their bodies. In this case, psychologists, gynecologists and pediatricians recommend talking with the teenager and carefully explaining the situation so that the girl does not develop depression.

Factors affecting growth

Not all teenage girls develop breasts the same way.

The shape and volume of the mammary glands depend on factors:

• Hormonal background. Each person has an individual hormonal background. If there is not enough estrogen in the blood, then the mammary glands will grow extremely slowly or they will not develop at all.
• Heredity. Medical statistics confirm that all women from the same family have breasts of the same size in 99% of cases. If the girl's mother, grandmother, aunt has a lush bust, then she will inherit a similar breast size.
• Food. A balanced diet is an important factor for the development of beautiful breasts. If the girl's weight is too low, then due to the lack of the necessary adipose tissue, the mammary glands will not be able to grow fully. But even in the presence of excess weight, breast development occurs with serious deviations. If the necessary measures are not taken in a timely manner, then the girl in the future may face problems when breastfeeding the child.
• Ecology. Living in a region with an unfavorable ecological situation negatively affects not only the intensity of breast development, but also the general condition of children and adults. Due to poor ecology, endocrine pathologies can occur, which are associated with the presence of disorders in the thyroid gland. In severe cases, the development of the child will be associated with the occurrence of various diseases.
• Region of residence. It has been scientifically proven that in the southern latitudes, girls reach puberty much faster than their peers from the northern regions.
• Physical activity. Lack of physical activity in children negatively affects the work of the whole organism, including sexual development. Regular exercise will help keep your muscles toned and your breasts firmer.

Signs of breast growth in girls are most active during puberty. But even at a young age, girls can develop various diseases related to the formation of the mammary glands. Medical statistics confirm that 12% of schoolgirls aged 10 to 14 years are diagnosed with breast pathologies, which is why teenage girls are registered with a pediatric gynecologist.

The growth of the mammary glands is largely dependent on the functioning of the stomach, intestines, liver and kidneys. The presence of pathologies in the work of these organs can significantly slow down the intensity of breast development, significantly worsening the girl's well-being. If a child complains of constant or recurring pain in the groin and abdomen, then you need to undergo a comprehensive examination of the body and consult with your doctor.

The reasons for the lack of development

If there are abnormalities in sexual development, the breasts may stop growing. Most often, this situation is associated with a lack of estrogen in the body. Gynecologists say that the development of the mammary glands depends on many aspects.

Lack of breast growth in 99% of cases is associated with the following factors:

• Body type, weight. Underweight girls most often experience a lack of breast development. Teens may be worried about this, but in fact, their breasts are growing, but not as actively as their peers with a thicker physique.
• Underwear. An improperly fitted bra can significantly impair blood circulation in the bust area, while compressing the breasts. Gynecologists recommend giving preference only to high-quality natural cotton underwear.
• Hormonal disorders. This is one of the most serious reasons for slow breast development. Failure of the hormonal background can be associated with an unbalanced diet, as well as with the development of hereditary pathologies. This cause of poor development of the mammary glands occurs in 1-2% of adolescent schoolgirls.

If a girl's breast growth has slowed down and raises concerns, then it is better not to postpone a visit to an endocrinologist. Hormonal imbalances can negatively affect the entire later life of a teenager. In severe cases, the doctor may prescribe the injections of hormones.

Why is there asymmetry during breast growth, is it normal?

In adolescent girls, asymmetry of the mammary glands is quite common. But in practice, in adult women, the mammary glands are different, which is absolutely normal. During the period of sexual development, under the influence of hormones, the breast develops in different ways - one more quickly and the other more slowly. Closer to adulthood, the difference in breast size becomes less noticeable.

When it comes to adolescence, then there is no need to worry about the asymmetry of the mammary glands. A young girl can feel anxious and even depressed, which is why she simply cannot do without the support of her mother.

Breast asymmetry can be dangerous when a girl has symptoms that are characteristic of the development of cancer.

Gynecologists say that every mother should make sure that her daughter is not disturbed by the following symptoms:

• Prolonged subfebrile condition. This is a persistent increase in body temperature (no more than 37.5 C).
• Lack of appetite.
• Increased fatigue, weakness.
• Painful sensations in the chest, itching, tingling.
• Weight loss.

So that a teenage girl is not ashamed of her appearance, you need to clearly explain to her what is happening with her body, and also help to choose a bra. It is not recommended to choose underwear with narrow straps that literally cut into the skin and impair the blood supply to the mammary glands.

Too tight and open bras contribute to breast deformation. It is harmful not only not to wear underwear, but also is in it all the time. Some girls mistakenly believe that the elasticity of the mammary glands can be preserved if not take off your bra before going to bed, but in practice, such a decision can lead to the development of various pathologies.

How old are girls' breasts?

Signs of breast growth in girls with an attentive attitude to the health of their daughters, caring mothers can notice even at the initial stage of sexual development. During this period, the girl's sweating increases, the pubis and armpits become hairy, the hips increase, and menstruation begins.

In 97 girls out of 100, the development of the mammary glands stops at the age of 18. It is at this time that puberty ends, a stable hormonal background is established, and the formation of the skeleton is completed. But in 3 girls out of 100, the growth of mammary glands continues until 20, and sometimes up to 25 years. Over the years, the shape of the bust changes, which is associated with pregnancy and breastfeeding of the child.

How to determine your breast size?

You can determine the size of your breasts using a measuring tape. The main task is to take measurements correctly.

In this case, it is recommended to adhere to 2 rules:

• A mother, grandmother or aunt should take measurements for a teenage girl, since only in this case can you get the most reliable result.
• Measurements should be done exclusively in a comfortable bra without foam inserts. If the girl is the owner of a magnificent bust, then in order to obtain the most accurate result, it is necessary to put on underwear without lining in the cups.

The first measurement is taken by the girth of the chest. With the help of a measuring tape, the measurement is carried out strictly under the mammary glands. In this case, the tape should not press on the skin. The second measurement is taken along the most convex part of the breast (most often these are the nipples). After that, it remains to correctly calculate the size of the cup. The measurement of chest circumference should be rounded up / down, taking into account the initial data.

For example, if the first measurement is in the range from 56 to 62 cm, then the result of the chest circumference will be 60 cm. If the girth along the most convex part of the mammary glands is 69-73 cm, then you need to use the value 70 cm.

To determine the size of the cup, subtract the value of the most convex part of the chest from the girth of the chest (70-60 = 10). A girl with such parameters will have a breast size of AA.

Cup size (cm)	Breast size
10-12	AA
12-13	BUT
13-15	IN
15-17	WITH
18-20	D
20-22	DD
23-25	E
26-28	F

Correct measurement is the key to choosing the correct bra size.

When should you buy your first bra?

There is no consensus on when to start wearing a bra. In practice, it all depends on physiological characteristics and genetic factors. Some girls start wearing a bra from 10-11 years old, while others only closer to 15 years old.

The following factors indicate the need to buy underwear:

• The girl begins to hesitate to change clothes in public locker rooms and on the beach, as there is a significant increase in the size of the mammary glands.
• The child is worried about painful sensations in the chest during physical activity (for example, brisk walking, running, jumping).
• The mammary glands, nipples become more visible under the blouse, T-shirt.

Having at least 1 of these factors is a good reason to buy a bra.

When choosing a suitable model of underwear, it is recommended to adhere to the following rules:

• Choosing a bra must be strictly in size. The underwear should not press and deliver uncomfortable sensations.
• Gynecologists do not recommend buying push-up bras, as they are contraindicated in adolescence. Otherwise, such underwear will interfere with the normal development of the breasts.
• The bra should be soft and wired. It is best to give preference to linen made from natural fabrics and with a minimum amount of decorative elements. In adolescence, lace bras are inappropriate.
• If the girl still has small breasts and a suitable size cannot be found, then it is recommended to pay attention to sports tops.

Following these simple rules will help you avoid common mistakes when choosing a bra.

Growth stimulation methods

The size and shape of the bust is 90% dependent on heredity and nationality. That is why not every girl can become the owner of magnificent forms without surgery. But the aesthetic beauty of the breast is assessed not only on the basis of its size, but also taking into account the elasticity and fit. For this reason, teenage girls can independently influence the formation of a beautiful breast.

To have a beautiful bust, you need to exercise regularly and eat right. During puberty, girls' diet should include foods that are rich in vitamins, minerals, amino acids.

For example:

• Cereals, cabbage of any kind, legumes. These products contain folic acid, which promotes cell regeneration and is beneficial for the female body.
• Phytohormones are found in pumpkin, flax seeds, greens, soybeans, and walnuts.
• Orange fruits and vegetables contain beta-carotene, which is a strong antioxidant and helps prevent the development of cancer.

It is imperative to drink 1.5 liters of clean non-carbonated water per day.

At the stage of active growth of the mammary glands, gynecologists recommend engaging in active sports. Exercise should focus on strengthening the chest muscles.

For example:

• Jumping rope.
• Push-ups from the bench or from the floor.
• Ball squeeze exercises.

Exercise should be done regularly, but excessive exercise is contraindicated. To achieve maximum results, 3 sessions per week are enough.

What should i avoid during breast growth?

An appointment with a gynecologist with diseases of the genitourinary system is often visited by girls aged 14-17 years old who mistakenly believe that taking birth control pills can increase size breasts. In fact, oral contraceptives help to enlarge the mammary glands due to the deposition of adipose tissue, but the girl begins to rapidly gain weight. After the termination of the use of contraceptives, the breast gradually returns to the size laid down by nature.

Qualified gynecologists and mammologists prohibit independently interfering with hormonal levels. Otherwise, the girl may develop pathologies that disrupt reproductive functions and can affect the occurrence of oncological neoplasms.

When the first signs of breast growth appear, it is recommended to revise the diet so that it includes only high-quality and healthy foods, and it is also necessary to exercise. Massage helps to stimulate the development of the mammary glands in girls, which is enough to do for 3-5 minutes. daily. The foods you eat should be rich in phosphorus, calcium and iron. If you follow all the recommendations and respect your health, the breast will develop correctly and exactly on time.
