Breast asymmetry correction

Breasts are very seldom mirror images of each other — they are often described as sisters rather than twins, and minor differences are entirely normal. Asymmetry can involve far more than size: the shape and contour, the size and position of the nipple and areola, the height of the breast fold, the breast’s base or ‘footprint’ on the chest wall, and the tissue around the breast can all differ between the two sides. Where the difference is marked enough to affect clothing, comfort or confidence, symmetrisation surgery aims to improve the balance between the breasts and produce a result that is proportionate to your body.

Anaesthetic: General
Hospital stay: Day case or 1 night

What it involves

Correcting asymmetry almost always means an individually planned combination of procedures, and frequently a different operation on each side. Depending on what is causing the difference, treatment may involve enlarging a breast with an implant, reducing the larger breast, lifting one or both, adding volume with fat transfer, reshaping or repositioning the nipple and areola, or treating the tissue around the breast and chest wall. One breast may need an uplift while the other needs augmentation. Incisions depend on the procedures chosen — in the fold beneath the breast, around the areola, vertically between the two, an anchor-shaped incision, or small incisions for liposuction and fat transfer. The operation is usually performed under general anaesthetic and typically takes one to three hours.

Who it may suit

May suit you if there are differences in breast size, shape, nipple or areola size or position, the breast fold, or the breast base — whether present since puberty, following tuberous or uneven breast development, or developing after pregnancy, breastfeeding, weight change, injury, previous surgery or treatment for breast disease. Planning requires a detailed examination of both breasts, the chest wall, skin quality, existing tissue and your proportions, and photographs and measurements are usually taken. One important exception: new, unexplained or rapidly developing asymmetry should be medically assessed before any cosmetic or reconstructive surgery is considered.

Recovery

Most patients go home the same day or stay one night. Early recovery takes about one to two weeks, with light daily activities usually possible within a few days and a return to work commonly after one to two weeks depending on the surgery and the work. Strenuous exercise and heavy lifting are avoided for about four to six weeks, and a support bra is worn as directed. Swelling, bruising, tightness and temporary differences between the breasts are normal early on — the breasts often look higher, firmer or more uneven at first, and the final shape takes several months to settle. Drains are sometimes used depending on the procedures performed, and are removed once drainage has reduced.

Common questions

Will my breasts be perfectly symmetrical afterwards?

No, and that is worth saying plainly. Perfect symmetry cannot be achieved or guaranteed. Small differences in size, shape, position, scars, nipple appearance or breast base will remain, and the two breasts may heal, age and change differently over time. The aim is meaningful improvement in balance and proportion, not a mirror image.

Will it affect breastfeeding?

It depends which procedures are performed. A reduction, an uplift, or surgery involving the nipple and milk ducts may reduce the ability to breastfeed, and changes in nipple sensation can also affect it. This is discussed at consultation, and it matters if you may want to breastfeed in future.

Do I still need mammograms afterwards?

Yes. Breast surgery does not remove the need for routine breast screening. Always tell the radiographer or healthcare professional about any implants, fat transfer or previous breast surgery before a mammogram or other breast imaging.
