Mismatched Breasts

It's a problem more common than most women realize. Still, while no woman has perfectly matched breasts - one is always larger, slightly higher, or shaped differently than the other, in most women these imperfections are barely noticeable. For others, the problem may be more extreme to the point where their self confidence and esteem are compromised.

Asymmetry can be measured by simple tests. Some women have different nipple-areola positions and don't even know it. For a quick evaluation, measure the distance from your sternal notch, which is just below your Adam's apple, to you nipples. If they are evenly positioned, the distance should be the same.

A breast lift can correct asymmetrical areola/nipple positioning and breast augmentation can correct a difference in size.

The Rice Test

While volume and shape are easy to judge from a qualitative point of view, an exact measurement of breast volume asymmetry is best taken using what is called the Rice Test.

Using a bra that fits your larger breast, fill the cup of the smaller breast with a small plastic bag filled with rice until the size for both breasts looks the same. Then, pour the rice into a measuring cup to read its volume. This volume, measured in millimeters, is the equivalent of the mismatch in CCs (cubic centimeters).

For women seeking cosmetic surgery for correction, the Rice Test is a helpful way to determine the size of implant for the smaller breast.

Poland's Syndrome

Sometimes, mismatched breasts are evident simply by looking into a mirror. In many cases, such obvious discrepancies are the result of Poland's Syndrome.

Poland's Syndrome is caused by a restricted embryonic blood supply which can result in extremely asymmetrical breasts (as well as deformed arms or even a missing pectoral muscle).

Tubular Breasts

Tubular breasts are the most complex form of breast asymmetry. They are commonly associated with a drastic mismatching of the breasts. The major challenge is the tight and usually inflexible inframammary fold. Correction for this type of breast is typically to increase the width of the afflicted breast.
