One Breast Larger Than the Other

I hate having one breast larger than the other. Is there a breast surgery that can fix a full cup size difference? Do some women get only 1 breast implant to increase breast volume on one side?

Correcting Breast Asymmetry

Many patients considering breast augmentation are seeking to not only enhance the volume of their breasts, but to also enhance the shape and/or improve the symmetry of their breasts. Essentially all breast shape and symmetry issues can be improved during breast augmentation, and with most of them it is possible to make significant improvements and produce an aesthetically desirable breast profile. Accurate preoperative evaluation, appropriate surgical planning and attention to detail during the surgery are all crucial elements in achieving this goal.

Breast asymmetry is extremely common, and in fact essentially all breasts have some identifiable and measurable asymmetry. So the goal of surgery is not really perfect symmetry, as that does not exist in nature, but rather to produce the closest approximation of symmetry that is possible. In some cases it is possible to improve size asymmetry by using implants of different volumes and/or profiles. To do so one must patiently evaluate a wide variety of implant sizers intra-operatively with the patient in the upright sitting position. In some cases the breasts appear to be similar in volume, but asymmetries in the projection of the chest wall may mandate the use of different size implants in order to produce the closest approximation of symmetry.

For some patients it is actually quite important to reduce the volume of the larger breast (hence the somewhat confusing term 'reduction augmentation'), which in turn allows the surgeon to use implants of the same or similar size. If there is a significant difference in breast volume, and one attempts to address that difference solely by using implants of different size, then the result may be acceptable early on but as time passes the breasts will age very differently. The smaller breast with the larger implant will tend to remain youthful and perky-appearing, while the larger breast with the smaller implant will gradually become droopy-appearing and may eventually assume the appearance of a breast hanging off of a small implant. Not a pretty picture.

Correction of significant breast asymmetry usually requires modification of larger breast

Simply placing an implant in the smaller breast will not compensate for the asymetry. This is because the larger breast has more skin and usually rests lower on the chest.

Soft tissue expansion of the smaller breast can occaisionally compensate by stretchning the skin of the samller breast to create some sagging of the breast to match the larger side.

However more commonly, the larger breast is reduced or lifted to create a symetrical position and the smaller breast is enlarged with an implant. Both breasts may be enlarged at this operation if desired.

Breast Asymmetry


Thanks for the question. In short, breast asymmetry is common feature among most women. These asymmetries can be congenital or a consequence of changes that occur to the body throughout life (as a consequence of breast feeding, for example). There are various solutions to the problem of asymmetry.

Certainly, a breast reduction can be performed on the larger breast to try and achieve symmetry, while another likely scenario is to augment the smaller breast. These decision pathways are generated and are largely depent on the "starting product" or condition of your breasts.

I would recommend following up with your local Board Certified Plastic Surgeon and getting a thorough assessment so that the right management plan can be designed for your particular case.

Best of luck!

Breast asymmetry or uneveness in size

There are many different dimensions to measure when considering treating uneven (asymmetric breasts). If everything else is even, the easiest solutions may be lipsuciton on the larger side. I have included video clips with liposuction used during breast enlargement. More often than not, there are other issues that need ot be treated such as uneven or unequal heights of the nipples, areolae, creases, or skin quantity. This may require more surgery and more icncisions/scars.

Apples to apples NOT apples to bananas

There are really multiple ways to fix this and each has pros and cons.  Doing a history and physical (i.e. getting to examine you) would be very important in making the best recommendation.  Typically, implants and a mastopexy or small reduction may be required though if depends on your goals and I would tailor the treatment to your priorities.  Generally, if there is more skin on one side or the other, I think it is helpful to reduce the larger breast to the size of the smaller and then proceed from there.  Rarely, one could have an augmentation on one side and possibly a mastopexy (breast lift) on the other.  If you put an implant in one side or do a mastopexy on one side, it is generally going to look more symmetric in my opinion to do the same thing to the other side, to keep it apples to apples and not apples to bananas!! Hope that helps a little.  Good luck - find a good board certified surgeon and you will do well 

Re: Uneven sized breasts.

Thank you for your question.

It is common for some degree of breast asymmetry to be present. 

In cases when it is significant, and a patient is considering a breast augmentation- using two different sized implants may help. 

If a component of the asymmetry is size, as well as, shape- then it may be a more complex dynamic.

You would be best served to have a meeting with a board certified plastic surgeon to better define what is necessary.

Thank you, and best wishes,

Asymmetrical breast is more common than one would think. The variation of asymmetry differs from person to person and can cause pain and discomfort when wearing a bra, in server cases. Correcting breast asymmetry can be done a few different ways depending on the type of repair that would need to be done. I've helped many women with this same issue and most breast symmetry issues can be addressed with a breast augmentation, however, it s not the only option. It's would be best to talk with a board certified plastic surgeon with experience in this area.

Asymmetric size of breasts

All women's breasts are asymmetric, it is just a question of degree. In addition to this asymmetry, it is also up to the patient as to what aspect represents a cosmetic concern - do you see one breast as being to small or too large? This would mean you either need an augmentation or a reduction to achieve your goals. Or are both too small but one is worse than the other? In that case you would need both sides augmented, but to different degrees. 

It is definitely worth discussing your concerns in a formal consultation and I recommend finding a plastic surgeon to do so with.

Good luck!

Correcting Breast Asymmetry

It's very common for women to have breasts that are asymmetrical. What is done about it, depends on your current and goal breast size.
Sometimes a larger breast requires a reduction and lift to match the smaller breast. Often times the larger breast will have more ptosis (sagging). This is corrected by performing a lift.

If the larger breast is at your goal size, an augmentation of the smaller breast can be performed. Often times a lift is then performed on the larger breast to create a perkier shape.If you would like to increase the size of both breasts been in asymmetrical breast augmentation can be performed to bring their size closer together.It's important to understand that asymmetries will exist after a corrective surgery. The goal is to make these asymmetries less noticeable, but it's difficult to correct asymmetry 100% because small differences will always be present.

Correction of Breast Asymmetry

While it is more the norm to have some natural asymmetry in size or shape between the breasts, as plastic surgeons we try to minimize the difference as much as possible. Some residual asymmetry almost always remains however, and this should always be explained in advance. When there is a difference in size of one cup or more it is almost always necessary to do different operations on each breast. The smaller side generally needs an implant and possibly a lift, whereas the larger side generally needs a lift, and possibly an implant. The final decision is made after a detailed discussion with your plastic surgeon based on measurements, and ideally with the use of 3D imaging with computer simulations. Even with the best of technology and technique, there will likely always be a difference, albeit less, between the left and right breasts.
