Asymmetrical Breasts: Causes & Fixes of Uneven Breast Size

Uneven breasts mean the breasts don’t appear to be identical. Perhaps one is slightly bigger or sags a bit lower. Such a situation may make one anxious, but in most cases, it is very normal. 

Breasts present in a wide range of sizes and shapes. It is normal for one breast to be slightly larger or smaller than the other. Most girls and women will have some variation in their two breasts at some stage in life.

Continue reading this blog to the end if you want to learn about all the causes of asymmetric breasts, how they occur, what to look out for, and what you can do if you are concerned.

What Are Asymmetrical Breasts?

Asymmetrical breasts occur when one breast is larger or feels different from the other. This can be that one is ever so slightly bigger or smaller. One may be rounder, or one nipple may be higher or lower than the other. Sometimes it is tiny and difficult to see. Other times, it is more noticeable.

Apart from unevenness, how to get bigger breasts is another common concern when it comes to the female body.

What Causes Uneven Breasts?

Why is one boob bigger than the other? If you have the same question, know that there are numerous reasons breasts might not be even. 

Let’s examine each reason more closely:

1. Normal Body Difference

Nobody is ever perfectly symmetrical. Everyone has some slight variation in the shape or size of their eyes, ears, legs, or hands. The same goes for breasts. It is normal for one breast to be slightly larger or smaller than the other. Bodies are just not like that. 

2. Hormonal Fluctuations

What causes one boob to be bigger than the other? It often happens due to changes in hormone levels. During puberty, one breast might grow faster than the other. Even if they stop growing at the same time, they can still end up different in size or shape. Hormones can also affect breast size during periods, pregnancy, and breastfeeding.

3. Injury or Trauma

Sometimes, an injury like a fall or accident can cause one breast to swell and look bigger. This is usually temporary and goes down as the area heals. If the breast still looks unusual after a few weeks, it’s best to see a doctor.

4. Changes in Menstrual Cycle

Breast size may change during your menstrual cycle due to water retention. One breast may swell more, making it look uneven. This is normal and often changes throughout the month, with breasts usually looking most even around ovulation.

5. Medical or Growth Conditions

In rare cases, uneven breasts can be caused by a medical condition:

• Juvenile Hypertrophy: It is a condition where one breast becomes significantly bigger than the other during puberty.
• Scoliosis: It refers to a curve in the spine that may alter the way your chest appears. It can cause one side of the chest to protrude more, making one breast appear higher or larger.
• Deformities of the Chest Wall: Poland Syndrome, funnel chest, or pigeon chest, are issues with how the bones in the chest develop. They may influence the position of the breasts or their development.
• Breast Lumps or Cysts: The presence of fluid-filled sacs, soft lumps, or fibroids may also alter the shape and size of the breast. 

If you suspect any of these conditions, it’s essential to consult your General Physician to rule out.

6. Breast Cancer Risk (Rare)

It’s extremely uncommon, but an unexpected or significant change in one breast in an adult woman is occasionally a symptom of breast cancer. This is more probable if your breasts have always been even, and then one of them started to change its shape, size, or texture.

Asymmetry of Breasts: Signs to Watch Out for

If you’re wondering whether your uneven breasts are normal or not, here are a few things to look out for:

• One breast is larger or smaller than the other.
• One sits higher or lower on the chest.
• One nipple is in a different location or points in a different direction.
• You feel a new lump or thick area in one of your breasts.
• One breast feels sore, heavy, or swollen..
• The skin appears different (dimpled, red, or shiny).

If you’ve had them for a long time and they’re not causing severe issues, it’s okay. But if something feels new or doesn’t feel right, see your 

Is it Normal to Have Different sizes of Breasts?

Is a breast size difference normal? Yes, it is really normal. Most girls and women actually have a little bit of difference between their two breasts. You might not notice it under clothes, but it exists.

Remember:

• Having lopsided breasts is normal and human.
• Half of all women have some breast asymmetry.
• For most people, the difference is very slight, while they only notice it at specific times, such as when they’re about to get their period.

What’s most important is how you feel. If it’s not letting you feel at your best, it’s alright to discuss it with an expert practitioner so that they may guide you towards the proper fix.

Does Cancer Cause Asymmetric Breasts?

This is a nagging concern, but the response is usually no. Most lopsided breasts aren’t cancerous. Breast cancer is uncommon in young girls and teens, and even in adults, isn’t always associated with changes in breast size.

But cancer occasionally produces:

• A sudden change in breast form or size
• A hard, fixed lump
• A change in the skin (dimpling or colour)
• Nipple alterations (pulling in, discharge, or tenderness)

How To Fix Breast Size Difference?

So, now the question is how to fix an uneven boob?

Breast Asymmetry Treatments: Surgical Options

• Fat Transfer

Fat is taken from another part of your body, such as your thighs, hips, or stomach, using liposuction. The fat is then cleaned and injected into the smaller breast to increase its size. This option is popular with people who want a subtle change without using implants. It’s also helpful for shaping and improving the feel of the breast. The results are usually softer, but may require more than one session to reach the desired volume.

• Breast Reduction Surgery

Breast Reduction Surgery is used when one breast is noticeably larger than the other. The surgeon removes fat, glandular tissue, and sometimes skin from the larger breast to reduce its size. This may make both your breasts appear more equal in size and shape. Many people choose this option if the larger breast feels heavy or causes shoulder or back pain. Recovery may take several weeks, and you’ll usually need to wear a supportive bra during this time.

• Breast Augmentation Surgery

If one breast is smaller, the practitioner may place a breast implant to increase its size and match it more closely with the larger one. This procedure is called breast augmentation surgery and is often done under general anaesthesia and takes about one to two hours. Regular check-ups are necessary to ensure that the implants remain in good condition.

Apart from surgery, there are some natural ways, which may not give a permanent solution, but may help you cope with uneven breasts in daily life.

Bras & Padding

Experiment with bras with additional padding or insertable inserts. Some bras are designed to balance breast size and shape. Getting a good bra fit can make you feel more balanced and comfortable.

Exercise

Chest exercises, such as push-ups or light weights, can help strengthen your chest muscles. Toning your muscles may give your breasts a better lift and shape.

They might not change your breast size or correct asymmetry on breasts, but they may help your posture and boost your confidence.

Asymmetry in Breasts is Normal, But Solutions Are Available.

Can breast asymmetry be corrected? Yes! But first, remember that asymmetrical or uneven breasts are normal. Most individuals have some disparity, even if they don’t discuss it. Your body is one of a kind, and slight changes are a natural part of growth and development.

If your breasts have always been asymmetrical, do not worry. If you notice something suddenly or it does not feel right, talk to your doctor. There is advice, support, and help out there.

Above all, be gentle with your body. It works hard for you day in and day out.

However, if uneven breasts are affecting your confidence or comfort, it’s a good idea to speak to a specialist at Yorkshire Skin Centre about the best and safest options. An expert can help you explore what feels right for your body.
