Breast asymmetry refers to a difference in the appearance of one breast compared to the other, or a part of the breast compared to the rest of that same breast. A radiologist will examine a mammogram to look at differences in the breasts' position, volume, and form.
Understanding Breast Asymmetry
Breast asymmetry is a common condition where the breasts differ in size, shape, position, or volume. While slight asymmetry is normal, significant differences can sometimes be a cause for concern and warrant further investigation.
How Breast Asymmetry is Evaluated
Radiologists assessing mammograms look for several key indicators of asymmetry:
- Position: Differences in the placement of the breasts on the chest wall.
- Volume: Variations in the overall size of each breast.
- Form: Discrepancies in the shape and contour of the breasts.
Factors Contributing to Breast Asymmetry
Breast asymmetry can arise from a variety of factors including:
- Genetics: Inherited traits can influence breast development.
- Hormonal changes: Fluctuations during puberty, menstruation, pregnancy, and menopause can affect breast size and shape.
- Trauma or surgery: Injury or previous surgical procedures can alter breast symmetry.
- Weight fluctuations: Significant weight gain or loss can impact breast size and shape.
- Underlying medical conditions: In rare cases, breast asymmetry can be a sign of an underlying medical condition.
When to Seek Medical Advice
While minor breast asymmetry is usually normal, it's important to consult a doctor if you notice any of the following:
- Sudden or significant changes in breast size or shape.
- New lumps or areas of thickening in the breast.
- Nipple discharge or inversion.
- Skin changes, such as dimpling or puckering.
- Pain or discomfort in the breast.
