Why is One Breast Bigger Than The Other? | Guide to Breast Asymmetry

It is a common question many women ask - why is one breast bigger than the other? The truth is, breast asymmetry is quite normal and affects most women. It is estimated about 88% of women have breasts that are different in size, shape, or position.

What is Breast Asymmetry?

Breast asymmetry is when one breast is larger or differently shaped than the other. It can range from barely noticeable to more pronounced differences in size, shape, or position. While it is generally not a cause for concern, some people may feel self-conscious or uncomfortable about their asymmetrical breasts.

Causes of One Breast Being Asymmetrical

• Genetics: If your family members also have asymmetrical breasts, it is possible to inherit this trait.
• Significant Weight Gain or Loss: Fluctuations in weight can affect the size and shape of your breasts.
• Pregnancy or Breastfeeding: Hormonal changes can cause breast size and shape changes during pregnancy and breastfeeding.
• Hormonal Changes: Hormonal fluctuations during puberty, menstrual cycles, or menopause can also impact breast size and symmetry.
• Trauma or Injury to the Breasts: Any trauma or injury to the breasts, such as a fall or accident, can lead to breast size or shape changes.
• Breast Cancer Treatment: Some breast cancer treatments, such as surgery or radiation therapy, can cause breast size and symmetry changes.

In some cases, breast asymmetry may be caused by medical conditions, such as:

• Atypical Ductal Hyperplasia: This is a condition with abnormal cells in the breast’s milk ducts. It can cause one breast to be larger or have an irregular shape.
• Hypoplastic Breasts: Hypoplastic breasts refer to underdeveloped or small breasts. This condition can cause significant asymmetry between the breasts.
• Juvenile Hypertrophy: Juvenile hypertrophy is a condition where one breast grows significantly larger than the other during puberty.
• Poland Syndrome: Poland Syndrome is a rare condition where one side of the chest is underdeveloped, leading to breast asymmetry.
• Amastia: Amastia is a condition where one or both breasts are absent or underdeveloped.

Who is a Candidate for Breast Revision Surgery?

• Breast Augmentation: Breast augmentation involves using implants to increase the size and symmetry of the breasts.
• Breast Reduction: Breast reduction surgery can help reduce the size of one breast to match the other.
• Breast Lift: A breast lift can help lift and reshape sagging or asymmetrical breasts.

What to Expect Following Surgery 
Following your surgeon's post-operative instructions for proper healing is important after breast revision surgery. You may initially experience some swelling, bruising, and discomfort, but this will subside over time. It is essential to take it easy and avoid strenuous activities during recovery.
