Couldn't find what you looking for?


Girls going through puberty who notice that one breast is significantly larger than the other may have all kinds of feelings, ranging from worry that there is something wrong with their physical development to simply being displeased by the aesthetic component. 


They may be quite surprised to learn that it is not only extremely common for the breasts to display significant asymmetry during pubertal development, but that all fully-developed female breasts also have a degree of natural asymmetry.


Look around — do you notice obviously uneven breasts in anyone but yourself? Not usually, and that's for good reason. We tend to notice perceived imperfections in own our bodies much more easily than imperfections in others.

Is there a difference of more than a cup size between your breasts? You may be self-conscious about this and wonder if there is anything you can do about it. You may also worry that there is something wrong with you. 

Should You Have Surgery To 'Correct' Your Uneven Breasts?

Where asymmetrical breasts are causing a woman significant psychological distress, surgery may be recommended by healthcare providers and will even, in some cases, be funded by insurance policies. Should a woman simply wish to attain an appearance that is more in line with her personal perception of ideal beauty, surgery to correct uneven breasts is also possible but will necessarily be self-funded. 

Women who wish to have surgery to "correct" their uneven breasts have two options:

  • Breast augmentation surgery to increase the size of the smaller breast to align it with the larger breast. 
  • Breast reduction surgery to reduce the size of the larger breast to align it with the smaller breast. 

The choice you make will, if no other medical issues are present, depend on your desired final cup size. (Though we'd recommend against choosing a cup size so big that it may cause you back and shoulder pain!) In some cases of breast asymmetry, one breast will also hang down much lower than the other, or the sizes of the two nipples may differ greatly. This, too, can be amended surgically. 

Should you be unhappy with your uneven breasts but not quite to the extent where you would consider surgery, wearing a breast prosthesis ("breast padding") on one side in your daily life or just for special occasions is also certainly a viable option. 

Do Asymmetrical Breasts Pose A Breast Cancer Risk?

Asymmetrical breasts, which are caused by hormonal fluctuations and normal human development, are not normally anything to worry about.


However, it is important to note that research has shown that women who have uneven breasts are indeed more likely to later develop breast cancer than those who have more symmetrical breasts.


An individual woman's risk of breast cancer increases, research confirms, by a ratio of 1.5 per 100 ml. Women with highly asymmetrical breasts are, therefore, wise to observe breast self-exams to feel for lumps at regular intervals, and to ask their primary care providers about more frequent mammogram breast cancer screenings. 

In Conclusion

Should you have significantly uneven breasts while going through puberty, there is every chance that they will "even out" by the time your breasts are fully developed. Women who are distressed by or unhappy with their asymmetrical breasts during adulthood can begin by consulting their primary care provider about their options. Those who are not distressed by the asymmetry of their breasts will still want to ask their doctors about more frequent breast cancer screening.
