Breast Asymmetry: Causes & Treatments

Breast asymmetry is common, occurring when the breasts differ from each other in size, form, volume or position. The majority of women experience some type of asymmetry with their breasts.

A woman’s breasts can change throughout her life, and most causes of breast asymmetry are normal. However, breast asymmetry due to differences in density can be a sign of cancer. Women should have mammograms regularly and consult with their doctors if they notice any sudden changes in breast symmetry.

That said, breast asymmetry is most often nothing to worry about, and there are several cosmetic surgical procedures that can treat breast asymmetry.

Below, the team at The Plastic Surgery Group discusses the causes of breast asymmetry and its treatments.

Causes of Breast Asymmetry

Some of the most common causes of breast asymmetry include the following:

  • Genetics
  • Pregnancy
  • Breastfeeding
  • Menopause
  • Changes in hormones, such as during the menstrual cycle or due to hormonal contraceptives
  • Injury
  • Weight loss or gain
  • Poor posture
  • Uneven ribcage formation

Certain medical conditions may also result in breast asymmetry:

  • Poland Syndrome
  • Amastia
  • Tubular breasts

Treatments for Breast Asymmetry

Treatment for breast asymmetry varies depending on how the breasts differ, the breasts’ size and shape, and the patient’s goals.

Here are three treatment options:

Breast augmentation

A breast augmentation can be performed to increase the size of the smaller breast. Either a breast implant can be inserted into the smaller breast or implants can be inserted into both breasts, with one implant being larger than the other to correct the sizing imbalance.

Breast reduction

A breast reduction can be performed to decrease the size of the larger breast. During the procedure, loose skin is removed from the larger breast and the nipple areola complex is repositioned. In some cases, this procedure is performed on both breasts by removing more tissue from the larger breast to create symmetrical results.

Breast lift

Sometimes, one breast sags significantly more than the other and a breast lift may be the best option. During the breast lift, the excess, sagging skin is removed from the breast to shape and contour it in a way that matches the other breast.

A Message from PSG

As COVID-19 spreads across the country, our patients’ and our staffs’ health and welfare are our primary concern. To reduce the risk of spreading the virus we are implementing changes to reduce person to person contact. We may only be able to see urgent consults and follow ups. This applies to our offices as well as our clinics at the hospital. If appropriate, our staff may contact you to arrange a telephone appointment. As our senior population are at greatest risk, we will endeavour to reduce their exposure by deferring in person appointments unless absolutely necessary. Regrettably, there is a high likelihood your upcoming procedure or surgery may be deferred. If so, we will make every effort to rebook you as soon as the COVID-19 crisis resolves. We are closely following the guidance of the Ministry of Health and the Fraser Health Authority. We appreciate your patience and understanding.
