Female breasts shapes: What to know

Women’s breasts come in a variety of shapes and sizes. The shape and size of a person’s breasts, areolae, and nipples can be influenced by heredity, age, body weight, and hormone levels.

So, when it comes to breasts, what constitutes “normal”? What are the dimensions of your breasts?

The response is that your breasts are one-of-a-kind, and it’s absolutely fine if they’re different shapes and sizes.

Only inexplicable discomfort and sensitivity are out of the ordinary.

If you’re still not convinced, keep reading to learn about the various breast shapes and how to spot yours among them.

Breast shapes

The chapters below describe in details the various types and shapes of a woman’s breast.


Round breast shape

The breasts are totally round, as the term implies, which means that their size at the top and bottom are same.


Teardrop breast shape

Teardrop breasts resemble bell-shaped breasts in appearance. Teardrop breasts, on the other hand, are rounder and just slightly fuller on the bottom than on the top.

Bell shaped

Bell shaped breast shape

Because it resembles a bell, this breast shape was given its name. The top of the breast has a small width, while the bottom of the breast has a round and full shape.


Conical breast shape

Conical breasts are shaped like a cone.

The tops of the breasts slope down towards the outward-pointing nipples. People with smaller breasts are more likely to have this type.


Relaxed breast shape

Breast tissue that is looser or thinner has a relaxed or extended shape.

On relaxed breasts, the nipples are usually lower and may or may not tip downward.


East-West breast shape

East-West breasts are large on top and bottom, and the nipples point away from the body’s midline in different directions.


Close-set breast shape

Simply said, these breasts are extremely close together, with very little space in between. The breast and armpit are separated by a greater distance.


Side-set breast shape

Unlike close-set breasts, the breasts are closer to the armpits, resulting in a greater distance between them and more room between them.

Asymmetrical breasts

Asymmetrical breasts

When one breast is a different shape or size than the other, this is known as breast asymmetry.

The majority of persons have some asymmetry in their breasts. If a person is unhappy with the way their breasts look or if breast asymmetry is interfering with their everyday activities, they should consult a doctor about treatment alternatives.

The dimensions of 87 women’s breasts were measured by researchers from Emory University School of Medicine in Atlanta, GA. In 62 percent of the women, the left breast was larger than the right, according to the study.

The degree of asymmetry, on the other hand, varies from individual to person. One breast may be visibly larger or smaller than the other in some persons. Minor discrepancies in other asymmetric breasts go overlooked most of the time.

The presence of unequal breasts or nipples is not always a medical emergency. However, if a person notices a change in the shape or size of one breast, they should contact their doctor.

Some adolescents, according to study, may have substantial breast asymmetry. Breast tissue illnesses, side effects from specific medical treatments, and inherited factors are all potential causes.

During a regular mammography or breast cancer screening, doctors may notice asymmetry in breast size or tissue density.

Researchers discovered a substantial link between noticeable disparities in breast volume and the risk of breast cancer in a 2015 study published in the journal Breast Cancer: Basic and Clinical Research.

According to the authors, individuals with breast asymmetry ratios of over 20% had a twofold increased risk of breast cancer. Breast asymmetry ratios are defined as the difference in breast volumes divided by the volume of the smaller breast.


The areola is the darker tissue ring that surrounds the nipple.

No two pairs of areolae are alike, just like breasts and other regions of the body. Areolae can come in a variety of shapes, colors, and textures.

The areola is usually 3–6 cm in diameter.  “Normal” areolae, on the other hand, may be larger or smaller than this average.

Areolae changes size and color during a person’s life, notably when a woman is pregnant or breastfeeding.

Areolae come in a variety of colors, including pink, tan, and brown. They can also have a variety of textures. Some appear to be uneven or bumpy, while others appear to be more round or round.


The nipple is a raised piece of tissue at the areola’s center. The mammary glands, which are responsible for producing breast milk, are connected to the nipple.

Each person’s nipples are different and unique. They come in a variety of shapes and sizes, including flat, puffy, bumpy, and hairy.

The following are some examples of nipples:

  • Puffy nipples: The areola and nipple produce a raised mound on the breast that protrudes or puffs outward.
  • Flat nipples: The nipple and the areola are both the same height.
  • Bumpy nipples: In the areola and nipple, there are oil-producing glands called Montgomery tubercles that are located beneath the skin. In some persons, these might be seen as little pimples on the areola.
  • Hairy nipples: Hair follicles can be found on the areola’s skin. The color and texture of the hair that emerges from the areola can vary.
  • Inverted nipples: Many individuals have inward retracting nipples. In response to chilly weather or sexual excitement, they may protrude.

What factors influence breast shape?

Some individuals may be curious about the elements that influence breast shape. The shape, tissue density, and size of a person’s breasts can all be influenced by genetics.

Other factors that may affect the shape of your breasts include:

Fat in the body

The glandular, connective, and fat tissue found in the breasts.

The milk-producing mammary glands are surrounded by fat, which gives breasts their distinctive spherical shape.


Estrogen promotes the development of mammary glands. It also helps to determine where fat is stored in the body.

Just before their menstruation, females may notice that their breasts expand. The increase in estrogen levels causes this alteration.


The body produces fewer reproductive hormones as time passes.

Reduced estrogen levels cause decreased mammary glands and glandular tissue loss, according to a study published in the journal Dermato Endocrinology.

The elasticity of the skin deteriorates with age, making the breasts appear smaller or larger.

Breastfeeding and pregnancy

Breast swelling can also be caused by hormonal changes during pregnancy and breastfeeding.

The size and number of mammary glands can grow as estrogen levels rise during pregnancy.

Once breastfeeding is stopped, the breasts should return to their normal size.

Breast shape-altering conditions

The sections that follow will go through some of the health issues that might alter a person’s breast shape.


Mastitis is an infection that produces inflammation in the breast. Infections can be caused by a plugged milk duct or scrapes on the skin.

Breastfeeding mothers are the ones who are more likely to have this condition.

Antibiotics are used by doctors to treat mastitis. They may also drain any abscesses that occur in the breast by surgically draining blocked milk ducts.


Adenosis is a noncancerous breast disorder defined by enlargement of the milk-producing lobules of the mammary glands.

The breasts may appear enlarged or lumpy as a result of this disorder.

Adenosis, on the other hand, usually does not require treatment and will go away on its own.

Juvenile hypertrophy

Juvenile hypertrophy is an uncommon disorder in which the breasts expand rapidly and excessively throughout puberty.

Although the specific cause of juvenile hypertrophy is uncertain, current studies imply that hormone imbalances and genetics may play a role.

Juvenile hypertrophy can result in the following complications in addition to fast breast growth:

  • the appearance of visible veins under the skin
  • pain or soreness in the breasts and back
  • redness and swelling of the breasts
  • thickening of the skin and underlying tissues of the breast

The first-line treatment for juvenile hypertrophy is breast reduction surgery.

To help ease symptoms and prevent additional breast growth, doctors usually recommend hormonal birth control and estrogen receptor-modulating medicine.

When should you go to the doctor?

Changes in the shape, size, or color of a person’s breasts might be caused by hormonal fluctuations, aging, or pregnancy.

Any substantial changes in the look of one or both breasts, however, should be reported to a doctor.

Individuals should see a doctor if they have any of the following breast cancer signs:

  • red, dry, or flaky skin on the breast or nipple
  • swollen lymph nodes near the armpit or the collar bone
  • dimpling of the skin on the breast
  • a new lump or mass that can be painless or tender, soft or hard, or round or irregularly shaped
  • nipple retraction
  • unexplained tenderness or soreness of the breast or nipple
  • unusual nipple discharge

A doctor can help you figure out what’s causing your breast changes and what the best treatment options are.

Antibiotics can be used to treat infections like mastitis. Hormonal therapy works well for juvenile hypertrophy and certain forms of breast cancer.

Treatments for breast cancer, on the other hand, differ depending on the stage of the disease.

Other options for breast cancer treatment include:

  • radiation therapy
  • surgery
  • chemotherapy
  • hormone therapy
  • immunotherapy
  • other targeted therapies


Breasts can grow in a variety of shapes and sizes. The shape of a person’s breasts, areolae, and nipples can be influenced by heredity, body fat, and age.

Changes in hormone levels can cause breasts to alter. During menstruation and pregnancy, many people report enlarged or tender breasts.

If you observe a substantial change in the appearance of one or both of your breasts, you should see a doctor.
