This is a very common concern among female adolescents-even adult women! But it is quite common for each breast to be slightly different in size, a condition called asymmetry. Breast asymmetry is defined as a difference of form, position or volume of the breast, and it affects more than half of all women, so your daughter shouldn't feel alone. In fact, one study of women who wanted breast augmentation with implants found that 88 percent had natural asymmetries. Today, doctors can measure the symmetry of a woman's breasts via mammogram or, in your daughter's case, a special type of three-dimensional laser scanning called SCAN-3D, though these tests are not routinely available at most breast imaging centers.

A common abnormality seen on mammogram results is breast asymmetry. Breast asymmetry is usually no cause for concern. Breast asymmetry occurs when one breast has a different size, volume, position, or form from the other. Breast asymmetry is very common and affects more than half of all women.
It is quite common for one breast to be bigger than the other as development occurs during puberty. Usually the breasts become the same size over time and do not need any treatment. However, if the breasts have not become more or less an equal size by the age of about 16 years old or near the end of puberty , they will probably remain unequal. About one in four adult women have some degree of asymmetry of the breasts. In some adolescents the problem is that one breast is overdeveloped, whereas in others the smaller breast is underdeveloped.
You and your boobs go way back. You probably know them so well by now that you could pick them out of a lineup if you had to. That's because boobs are a little like snowflakes—each with their own unique shape, texture, and characteristics.
