Uneven Breasts: Why Do They Happen?

Uneven boobs are a perfectly normal part of having breasts, and many folks experience at least some difference between them. Understandably, a drastic difference in size can make it difficult to shop for clothes and bras. If you’re curious about why you have uneven breasts -- and the ways you can even out their appearance, if that’s what you’d like to do -- keep reading this guide.

Why Are Some Breasts Uneven?

Uneven breasts are more common than you’d think. Breast asymmetry affects more than 50% of folks with breasts. In fact, in most cases, having uneven breasts is nothing to worry about, especially if they’ve always been this way and the change isn’t sudden or has another easily explainable cause.

If you’re wondering how breast asymmetry occurs, there are few ways it can happen:

  • Genetics
  • Nursing
  • Pregnancy
  • Weight changes
  • Hormone changes due to ovulation
  • Hormone-based contraceptives
  • Menopause
  • Puberty
  • A condition such as hypoplastic breasts or atypical ductal hyperplasia

Non-Surgical Ways To Remedy Uneven Breasts

If you want to make your breasts appear more even, there are plenty of ways to do so. Here are a few ways to even out your breasts without any cosmetic procedures.

1. Choose The Right Bra

When you’re dealing with two different-sized boobs, it can be a bit difficult to find a bra that fits you right. When you shop in your local department store, it’s more likely than not that the bras you try on may have a large gap or cup spillage as you accommodate the needs of one breast over the other. Not only is this uncomfortable for you, but it doesn’t look quite right, either. 

Finding a bra that not only fits your breasts but makes them appear even is a must-have. An  unilateral mastectomy bra can help in this department, even if you’ve never had a unilateral mastectomy. These bras offer super-soft modal fabric that stretch and skim to accommodate each boob, leaving behind irritation and gaping.

2. Bra Inserts 

If you want a realistic, more even look, but surgery is simply not in the cards for you, bra inserts may be a great option. These inserts not only come in many shapes, sizes, and materials, but they also fit perfectly into a pocketed bra meant to hold them.

There are a few types of bra inserts out there, including heavy silicone inserts, lightweight foam ones, and partial inserts that offer a bit of filling out. And then there’s  F(oo)BS, AnaOno’s lightweight and versatile foam bra insert that can help you achieve that even look you’re going for. F(oo)BS  provide a more natural, seamless appearance without weighing on your back, neck, and shoulders. That’s because they’re specifically molded to either side of your body, so you can order the right side for the breast that needs a bit of balance.

3. Breast Prosthesis

A breast prosthesis is the most realistic-looking form often worn by those who’ve had a mastectomy. Prosthesis comes in many materials, such as silicone, foam, or fiberfill. A fiberfill or foam is perfect to add to your bra or swimsuit, whereas a silicone form will resemble a breast more and may be better for special occasions. While each of these are great options, you may want to consider materials, weight, and how often you’re going to use them before purchasing. 

Surgical Ways To Remedy Uneven Breasts

If you don’t want to deal with the hassle of breast forms and inserts and want a more permanent solution, breast surgery may be a better option for you. Here are the options that may help uneven breasts appear more symmetrical.

1. Breast Augmentation

You may have heard this procedure described as a “boob job,” but breast augmentation refers to a specific subset of breast surgery where implants or fat tissue are placed in your breasts. There are multiple ways to tackle this procedure, including fat transfer breast augmentation. This procedure injects fat from other areas of your body into your boob, evening out its appearance and helping it look closer to the bigger breast. Depending on your health, current medications, and medical history, your doctor may recommend fat transfer breast augmentation or a different type of cosmetic surgery.

2. Breast Lift

If you want a more youthful, even shape to both your breasts, a breast lift may be the right option for you. A breast lift will remove excess skin and tighten loose tissue, giving you a full and even appearance on both sides. There are four main types of breast lifts: crescent, peri-areolar, vertical, and inverted T. These four breast lift types refer to the shape and placement of the incision. Make sure to research your options and speak with your doctor to see which is best for your ideal look.

3. Breast Reduction

If you don’t want to add more tissue into your breast, another surgical option is breast reduction. This procedure alters your breast size by removing tissue, fat, and skin, ultimately leaving you with two smaller, similar boobs.

If you’re considering cosmetic surgery, it’s important to conduct research to find the best doctor for you. As you search for the best surgeon, look for their experience, read reviews, hospital affiliations, and their understanding of and specific experience with the procedure your doctor recommends. To find an accredited surgeon, visit the  American Society of Plastic Surgeons website.
