What Causes Breast Asymmetry and Can Implants Correct It?

Breast asymmetry is more common than many realise. Most women naturally have some degree of size and/or shape difference between their breasts. However, when the asymmetry is noticeable and causes physical or emotional discomfort, surgery such as breast asymmetry correction may be considered after consultation with a GMC-registered specialist to determine suitability and risks

At Cosmetic Surgery Partners in London, our team of GMC-registered surgeons, including lead consultant Mr. Miles Berry, offer assessments and surgical options for suitable patients seeking correction of breast asymmetry.

In this guide, you’ll learn:

• What causes breast asymmetry
• How asymmetrical breast augmentation works
• Procedure types and options
• Expected recovery and results
• Why experience matters

What is Asymmetrical Breast Augmentation?

Asymmetrical breast augmentation is a surgical procedure designed to correct visible differences in breast size, shape, or position. Unlike standard breast augmentation surgery, the approach may involve using different implant sizes, shapes, or placements to achieve a more balanced appearance, where clinically appropriate.

Results vary for each patient. A consultation is necessary to determine the safest and most effective treatment plan.

🔍 Did You Know?
Studies suggest that more than 85% of women have some form of breast asymmetry, though most cases are mild and may not require surgical intervention.

Common Causes of Breast Asymmetry

• Genetics: Natural developmental differences
• Hormonal changes: Especially during puberty or pregnancy
• Trauma or surgery: Previous procedures or injuries
• Breastfeeding: Can affect size and tissue distribution
• Medical conditions: Such as Poland Syndrome or tuberous breast deformity

Some patients may also have differences in:

• Nipple height or areola size
• Breast projection or droop (ptosis)
• Chest wall shape

A qualified plastic surgeon will assess these factors during consultation and advise whether surgery is appropriate or if alternatives are better suited.

The Asymmetrical Breast Augmentation Procedure

The surgical approach varies depending on the degree and cause of the asymmetry. Common techniques include:

1. Implant-Based Correction
Different implant sizes or profiles may be selected for each breast to help restore balance. Implants may be placed:

• Under the breast tissue (subglandular)
• Under the chest muscle (submuscular)

2. Breast Uplift (Mastopexy)
In cases where one breast sags more than the other, a breast lift may be performed on one or both sides, sometimes in combination with implants, to achieve a more even shape and position.

3. Fat Transfer
Fat taken from another part of the body can be injected into the smaller breast to enhance volume in a subtle, natural way. This technique can also be used to fine-tune symmetry following implant surgery.

4. Areola/Nipple Adjustment
If needed, the surgeon may reposition or resize the nipples or areolas to help create a balanced appearance between the two breasts.

All surgical procedures carry potential risks and limitations, including scarring, infection, asymmetry, and complications related to implants or anaesthesia. Your surgeon will discuss these in detail, along with expected outcomes and recovery considerations, before any procedure.
