At What age do Girls Start to Grow Breasts?

At what age do girls start to grow breasts?

The development of a girl’s body begins at puberty, between the ages of eight and thirteen, and can last from two to four years until it transforms into the adult complexion. Your breasts will start to grow: the first changes will be tiny and the volume under the nipple will increase a bit (like a button). It is important to note that your breasts may grow unevenly and one breast may be smaller than the other for a time. As the girl develops, she may feel discomfort due to the sensitivity of the area or become uncomfortable with her own body, which will be in full growth until its development is completely finished.

The impact of puberty on girls

The growth of each child is unique and is not subject to a general rule. Anguish at this age does not discriminate against anyone: those who develop early have a complex with their bodies because they still consider themselves girls, and those who experience slower growth feel marginalized for not keeping up with the rest.

So we should try to educate them in self-acceptance and deal with their insecurities. Simply in some girls this process is slower or faster than in others, since each organism develops at a different rate. So that they do not feel shame about their own body, we must remove the taboo of nudity and teach them to self-examine, know themselves and take care of the chest area, to avoid blows in that sensitive area. Of course, it is prohibited to use hormones, steroids and other medications indiscriminately in order for them to develop earlier, as they could cause severe illnesses.


Why and how do breasts develop?

It can also be very interesting that we explain how the development of your breasts works scientifically:

The first requirement for the development of the breasts is that it must have started during the beginning of puberty, when the girls’ ovaries enlarge and estrogen –the female hormone– begins to circulate in the body, causing deposits in the breasts. of fat and growth of a wide duct system. At the same time, a thin layer of specialized cells, called epithelial branches, will form inside the tissues in the chest. These ramifications provide the breasts with a structural framework for fatty tissue that allows them to determine their size and shape. As if it were the shape of a container that would later swell.

The ramifications depend on certain hormones, but also on cells of the immune system called macrophages that help them change in each of the processes. These cells, which until now were unknown, will be in charge of ‘notifying’ the girl’s body that the time has come, just in the right place at the right time.

As adolescence progresses, the increase will be qualitative and quantitative , since the nipple and the circle of skin that surrounds it – called areola – become larger and darker a little. Then the sinus expands, generally acquiring a cone shape. After starting the ovulation and menstruation, breast maturation is perfected by other female hormones such as progesterone, which stimulates their development, and prolactin, which completes the work of turning them into milk producing organs.


The breasts stop growing at the beginning of adulthood, when they are fully developed, although they will do so again if she becomes pregnant to make room for the mammary glands, and then transform again when the mother stops breastfeeding. Some women scare from breastfeeding so they can checkout spectra s1 vs s2 to know more. Still, the ramifications will never stop growing and changing throughout a woman’s reproductive life, something unique in human tissues.


Teens increasingly sooner?

Although each development is different, the numbers of premature adolescence are alarming doctors. In the United States it is believed to be appearing a year earlier than a few decades ago. However, the causes are not entirely clear, although it is thought to be due, in part, to the rising rates of childhood obesity, long associated with premature sexual development. In fact, various works have shown that it is related to obesity, but this does not explain why the time of its onset varies considerably between different ethnic and socioeconomic groups, and it is earlier in black girls and those of more humble origins. It is a field in full investigation processAnd there are infinite hypotheses that we are increasingly exposed to environmental chemical agents that emulate hormones and may be accelerating puberty.

This early puberty abnormality is especially worrisome because, although each body develops differently, if a population that lives longer and longer reaches the adult complexion sooner, it may be a sign that something is not working correctly. There are also other hypotheses that suggest that when a girl’s breast begins to grow prematurely, it may be a sign that she is going to contract certain diseases in the future. There is evidence that early puberty carries an increased risk of obesity, type 2 diabetes, heart disease, and breast cancer. Girls whose breasts develop before the age of 10 have a 20% higher risk of suffering this disease throughout their lives than those whose breast develops between the ages of eleven and twelve. And, although they are not decisive data or do not mean that a girl who develops earlier will contract any of these diseases, it is subject to analysis. In fact, the role that an immune molecule called ACKR2 plays in the process is being studied, which prevents macrophages from moving into the breasts until the woman is old enough, preventing premature breast development.

But what we can surely do on our part is to fight with them in the possible feelings of isolation and shame and in the emotional damage that adolescence can cause them. And above all, accompany them to carry out a clinical examination of the breasts both at the time of their appearance and thereafter to detect any problems as soon as possible.
