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!

One breast larger than the other.

Hello! Thank you for your question! It is common for women to have asymmetry of her breasts. Usually, this is simply a benign finding, especially if it has been a finding since development. Sudden changes in one breast alone is more concerning.

If the asymmetry is bothersome to you, there truly is no "natural" way to achieve symmetry. Nothing short of a surgical procedure would ameliorate your issue. Options would be for augmentation of breast(s) with implant(s) of varying sizes or fat, reduction of breast(s) with excision or liposuction.

Consult with a plastic surgeon to examine examine and discuss the various options available. Your surgeon will help you decide for yourself which option(s) is the best for you. Best wishes!

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.

Breast Lift for Uneven or Asymmetrical Breasts

Those with #uneven or #asymmetrical breasts are candidates for #BreastLifts. They are among a category of candidates with #DevelopmentalBreastProblems. This includes women with one breast is lower than the other, those with tuberous breast deformity. Women with asymmetric or enlarged nipples or areolae (pigmented areas around nipples) also may be candidates for a breast lift or a modification of a lift. #Asymmetric breast can be adjusted by adding or removing volume. One side can be tightened more or less than another.

Breast asymmetry is very common

Most women have at least a minor difference in size or shape between the two breasts. Many times it is barely noticeable to the woman until she has a consultation for breast surgery. The breasts are carefully measured and photographed during consultation with plastic surgeon to help with determining just such differences, explaining what can and cannot be done and planning a procedure. 

While minor asymmetry is very common, major differences are a bit less common and of course can be very upsetting to women. There are approaches to address significant size differences. Typically, a larger implant is utilized for the smaller breast and a smaller implant for the larger breast. Although not impossible, it is much more difficult to match two breasts if an implant is only placed on one side.

When you consult with your plastic surgeon, he/she will be able to provide all options for improvement of asymmetry including, different size/shape implants, adjustable implants, fat grafting and breast reduction/lift if that is appropriate for the much larger breast. It is important to remember however, that despite a surgeon's best efforts, complete symmetry is rarely achieved!

Decrease the larger one or increase the smaller one

Breast asymmetry is the norm for women, since nobody has two breasts that are exactly alike. This makes correcting breast asymmetry more common than you may think. However, when the difference is so noticeable that it becomes a concern, you have a choice of increasing the size of your smaller breast with an implant, or decreasing the size of your larger breast with breast reduction surgery. A breast lift may also be performed on once side to reshape the breast. The goal of any surgical option you choose is to decrease asymmetry to the point that it is no longer a concern for you.

Correction of Breast Asymmetry

Thank you for your question.  Breast asymmetry is actually more common than one would think and I see many women each day in consultation looking towards a breast augmentation in the hopes of correction.  The cause of this asymmetry can be the cause of physical changes that occur over the course of ones life (pregnancy, breast feeding, fluctuations in weight, etc...) and/or congenital. Often, depending on the degree of asymmetry patients will require multiple courses of action and a physical examination is necessary to determine what this would entail.  For example, one breast may benefit from an implant alone and the other might require a breast lift or reduction with a small implant, or sometimes one breast will require a significantly larger breast implant than the other.  I always inform patients that they should not expect complete symmetry post-operatively, and that slight natural breast asymmetry is actually quite normal and should be expected.  A consultation with a board certified plastic surgeon who specializes in breast related procedures would be beneficial for you.  At this visit your concerns and goals can be addressed and a physical examination can be performed which will determine the best course of action.  I hope this helps and good luck!

Breast asymmetry options

Thank you for your question. Breast asymmetry is very common, particularly size asymmetry. If you are looking to decrease the asymmetry from one breast to another, then you have several options:
1) You can reduce the larger breast with liposuction or a traditional breast reduction technique
2) You can enlarge the smaller one with fat grafting or an implant
3) You can enlarge both but use different size implants
4) A lift procedure may also be needed to help address differences in shape, nipple position and areolar size.

I would visit with a board certified plastic surgeon to discuss your options in more detail.
