Understanding Breast Asymmetry
Breast asymmetry occurs when one breast differs from the other in size, shape, or nipple position. Various factors, including genetics, hormonal changes during puberty, pregnancy, breastfeeding, or medical conditions such as Poland syndrome or tuberous breast deformity, can cause this. Past surgeries, trauma, or uneven tissue development sometimes contribute to noticeable differences.
While minor asymmetry is entirely normal and often unnoticeable, significant variations may lead to self-consciousness and, in some cases, physical discomfort. Severe asymmetry in the size of the breasts, medically referred to as anisomastia, is generally related to a difference in volume. Women with significant breast asymmetry may seek the expertise of a qualified plastic surgeon, rather than a cosmetic surgeon, for medical advice and surgical correction. This distinction is important because plastic surgeons are specialist medical professionals who are trained in reconstructive procedures, and their work is often focused on restoring normal form and function.
In certain cases, breast asymmetry surgery may be deemed medically necessary if the circumstances meet specific criteria. Depending on these circumstances and the level of documentation from the plastic surgeon and general practitioner, this may make the procedure eligible for partial Medicare rebates or private health insurance coverage. If the surgery is purely cosmetic and to improve appearance without addressing medical concerns, neither Medicare nor private health insurance will cover it.
If you are living with breast asymmetry and considering your options, it’s important to consult with a board-certified plastic surgeon who is registered with the Australian Health Practitioner Regulation Agency (AHPRA) and a Fellow of the Royal Australasian College of Surgeons (FRACS). They can help assess your condition, explain the risks and benefits of surgery, and work with you to create a treatment plan tailored to your goals.
Procedures to Address Breast Asymmetry
When it comes to addressing breast asymmetry, surgical correction is typically the most effective option. Depending on the unique needs of the individual, patients might consider procedures such as breast augmentation (for those wanting to enhance a smaller breast), breast reduction (for those looking to reduce size), or breast lift (also known as mastopexy). In some cases, depending on the patient’s needs, a combination of these procedures can achieve symmetry:
Breast Augmentation (Augmentation Mammoplasty)
Breast augmentation is the most common choice for correcting asymmetry, especially when one breast is noticeably smaller than the other. This procedure involves placing an implant in the smaller breast to match the size and shape of the larger breast, creating a more proportional appearance. The size and shape of the implant are carefully selected to match the patient’s natural breast and achieve the best possible result. In some instances, implants may be used in both breasts with different sizes to reach optimal symmetry.
Breast Reduction (Reduction Mammoplasty)
For patients with one breast significantly larger than the other, breast reduction surgery can help restore proportion by removing excess glandular tissue, fat, and skin from the larger breast. This procedure not only improves symmetry but also alleviates discomfort associated with excessive breast weight, such as back and shoulder pain. Breast reduction surgery is an effective option for those seeking a more proportionate look and to address the symptoms of upper back, neck or shoulder pain associated with large breasts.
Breast Lift (Mastopexy)
A breast lift surgery, or mastopexy, is ideal for patients whose asymmetry is caused by differences in breast shape, droop, or nipple position rather than volume alone. This procedure reshapes and lifts the breasts. A lift can be performed on one or both breasts, sometimes in combination with augmentation or reduction, to achieve the desired shape.

What to Expect from Breast Asymmetry Correction
- Consultation: The first step is a thorough consultation with your plastic surgeon to assess the level of asymmetry, discuss aesthetic goals, and determine the best surgical plan.
- Choosing the right implant: Your surgeon will recommend the ideal implant size, type, and placement is suitable.
- Surgery: The procedure is performed under general anaesthesia and typically takes one to two hours. Incisions are made in a discreet location, typically under the breast fold (inframammary)
- Recovery: Patients usually return to light activities within a week and can resume normal activities, including exercise, within four to six weeks. Swelling and discomfort are common in the initial recovery period but subside over the next few months.
Breast Asymmetry Frequently Asked Questions
Q: How do I know if I need breast augmentation, breast reduction, or a combination of both?
A: This depends on the degree of asymmetry and personal preference. A consultation with an experienced breast surgeon can determine the best approach based on your anatomy and aesthetic goals.
Q: Can breast augmentation correct differences in nipple position?
A: While augmentation can improve overall breast size, it is possible that additional procedures such as nipple repositioning may be required for optimal results.
Q: Will my breasts look completely symmetrical after surgery?
A: No two breasts are ever perfectly identical, even after surgery. However, breast augmentation may improve symmetry and create a more proportionate appearance.
Q: Can I breastfeed after augmentation for breast asymmetry?
A: In most cases, yes. However, certain incision placements and implant positions may affect milk ducts, so it’s important to discuss this with your plastic surgeon if you plan to breastfeed in the future.
Q: Will the scars be noticeable?
A: Incisions are made in discreet areas, and scars tend to fade over time. Your plastic surgeon will discuss scar management techniques to help improve healing.
Q: What are the risks associated with breast augmentation?
A: Like any surgery, augmentation carries some risks, including infection, implant rupture, capsular contracture, and asymmetry. Choosing a qualified, experienced plastic surgeon minimises these risks.
Whether breast augmentation alone or a combination of procedures is needed, consulting with an experienced plastic surgeon will clarify the best approach and tailor a suitable solution.
