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.

Correcting breast asymmetry with #breastsurgery

Thank you for your question on correcting breast asymmetry with breast surgery (either augmentation or reduction).  It can be frustrating dealing with breast asymmetries, however rest assured that all patients present with some degree of differences from one breast to the other.  While some patients may opt to use prosthetic devices in the bra to help even things out, some prefer surgery.  In order to answer this question thoroughly you would do well to schedule an in person exam with a plastic surgeon certified by the American Board of Plastic Surgery, and preferably also a member of the ASPS (American Society of Plastic Surgeons) and ASAPS (American Society for Aesthetic Plastic Surgeons).  It is possible to only do an implant to one side, or even reduce and/or lift one side and do different sized implants.  Each situation is unique so unfortunately there is not a one answer fits all.  Very best to you.  -Brian S.

It is very common to have asymmetric breasts. I don't think there is a pair that is exactly alike!
But you have alot of options depending on the degree of volume difference and the amount to ptosis ("sagging") of the opposite breast. Some patients only need implants of different sizes, while others need a lift and others need a reduction depending on what their goals are. Talk to a plastic surgeon that you trust and let him/her walk you through your options.

Breast implants can help improve asymmetry

Having breasts of different sizes is actually the norm rather than the exception, even if the size difference may not be noticeable to anyone else. However, in a case like yours where one breast is a full cup size larger than the other, breast enhancement surgery can help. It’s certainly possible to use only one implant in order to augment the smaller breast to match the larger. Alternatively, you may consider a reduction on the larger breast to create a more balanced look. I suggest consulting with a board certified plastic surgeon to develop a customized plan that will help you see the best results.

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.
