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 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.

One Breast Larger Than the Other

Breast asymmetry is one of the common reasons that women look towards breast enhancement surgery.  While some natural asymmetry is normal & will usually remain after Breast Augmentation surgery, a breast that is significantly larger than the other will require virtually 2 plans of action.   One breast might benefit from an implant only, while the other might need a lift, implant or slight reduction.   This is a decision that you and your surgeon should come to after a lengthy discussion.  Good Luck!

Breasts uneven

This is a question I hear frequently. It is very common for women to have some breast unevenness, or asymmetry. Is the asymmetry extreme? If so, one option would be to add an implant to the smaller breast, another option would be to do a reduction on the larger breast.

Breast asymmetry

breast asymmetry is common. some are more pronounced than other.

to adjust asymmetry, the smallest breast can be increased or the biggest reduced.

if increasing the smallest one is desired. one implant can be used.

2 implants can also be used with different size

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.
