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?

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!

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.

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 Augmentation For Breast Asymmetry

Yes, it is common for different sized breast implants to be used to correct size asymmetry. You can also choose to have just one breast implant as well. However, please remember that breast asymmetry is very natural. Nobody has perfectly symmetrical breasts.

Uneven breast size

Uneven breasts is a fairly common problem.  Several procedures can be considered depending upon what you want.  Do you prefer the smaller breast?  If you do, then liposuction or a breast reduction can be done on the larger breast.  If you prefer the larger breast, then an augmentation on the smaller breast can be done.  Often to obtain the best symmetry, surgery is needed on both breasts.  There is more breast tissue, obviously, on the larger breast, but it also has more skin and usually a wider base.  I recommend seeing a board certified plastic surgeon to see what would be the best option for you.

A combination approach is often best for significant asymmetry.

It is definitely possible to get an implant only on one side. However, this may not be enough in and of itself to ensure that both breasts look closer to the same size and shape. Often, a combination approach is used: an implant in the smaller breast, combined with a slight reduction/lift for the larger breast. Alternatively, many women choose to get implants for both breasts, but in different sizes. This not only helps with the size concern, but also ensures that the shape and profile of each breast is more similar compared to having an implant only on one side.

Sisters not twins

Breasts are sisters, not twins - no woman's breasts are exactly the same - it sounds like yours might be more like cousins than sisters. There are many ways to approach breast asymmetry depending on the differences between your breasts (is it just size?  is it shape? how about nipple position?). The options include reducing the larger side, enlarging the smaller side (with your own fat or an implant), and enlarging both sides (using a bigger implant on the side of your smaller breast). Your best option can be determined by consulting with a board certified Plastic Surgeon.

Treatment of Breast Asymmetry

There are certainly options available to you.  These options range from augmentation of one breast with an implant or fat transfer to reduction of the contralateral breast.  Depending on the cup size you wish to be, I would discuss these options with a Board Certified Plastic Surgeon who is experienced in correction of breast asymmetry.

Best of luck,

Different sized breasts

Your breast asymmetry can be improved with different sized implants.  I typically place implants on both sides so that they appearance is more uniform, but we would place a larger implant into the smaller breasts to help even you out.  This is very routine for most PS.
