Factors That Determine Breast Shape and Size 

Under normal circumstances, a teenage girl’s breasts continue to grow into her 20s. But this situation is not the same for everyone. Although breast growth stops after a while, its sizes may change throughout your life. Because breast size and shape, estrogen level, diet, exercise, etc. may vary depending on various factors. You can examine the factors affecting breast growth from the following headings.

Factors That Determine Breast Shape and Size

Family History

According to a study, women are born with a breast size that can change throughout their lives. These dimensions can be determined depending on genetic factors.

Genes encoded in the body have a huge role in many structures of the body, from hair color to eye color. That’s why these genes that run in the family can be associated with the size of breasts.

Body Weight

Milk glands, milk ducts, supporting connective tissue and many tissues are specific to the person. If the breasts contain higher fat tissue than normal, this may disturb the person in weight gain. Large breasts can lead to health problems such as neck and lumbar hernia.

In such cases, women may resort to weight loss or breast reduction procedures. Breasts consisting of adipose tissue can cause sagging and cracks in weight gain with shrinkage when weight is lost. However, breasts that vary depending on weight vary from person to person.


Sometime after starting sports, breasts are likely to tighten and even grow in some cases with healthy eating and healthy weight gain. Pectoral exercises, such as a breast press, can strengthen the four main muscles in the breast tissue.

With the growth of these muscles, sagging of the breasts is prevented. Muscles grow, pushing the breast tissue outwards to have a larger appearance. However, it should not be forgotten that breasts are made up of adipose tissue. So the exercises will not enlarge your chest body, they will only help you tighten it.

Menstruation Cycle

During the menstruation period, some changes are experienced in the texture and shape of the breasts.  This is because in the first half of the cycle, your body begins to produce the hormone estrogen, which stimulates ovulation and the milk ducts in the breasts.

In the second half, when the period approaches, the hormone progesterone, which causes the breasts to swell, stimulates the formation of the milk glands. Then the breasts look fuller than they are. However, breasts that are more sensitive and larger than normal during the menstrual period return to their normal size at the end of the cycle.

Birth Control

Birth control pills, injections, and hormonal IUDs used to prevent unwanted pregnancy situations can affect the size of the breast. The reason is that hormonal birth control pills can cause estrogen and progesterone to retain water. However, due to these, they can cause growth or shrinkage due to increased appetite and weight gain.

Pregnancy and Postpartum

Breast growth, which is one of the symptoms of pregnancy, can actually be due to reasons such as weight gain, water retention and hormonal changes during pregnancy. During this period, the milk-producing glands increase the level of progesterone, which promotes the production of more milk ducts and lobules.

After birth, your breasts may continue to swell during breastfeeding. However, about 3-6 months after this period, it can return to its normal size.


As a person gets older, his body changes with him. Women’s breasts likewise begin to grow in adolescence. Then it stops growing.

In addition, hormonal changes during menopause, depending on age, can affect the size and shape of breasts.

As we age, the level of estrogen decreases, so the connective tissue becomes dehydrated. As a result, the breast loses its elasticity, shrinks or sags. Nevertheless, if there is a sudden shrinkage or sagging in such cases, a doctor should be consulted.
