Breast asymmetry is a condition in which the breasts are not symmetrical, i.e. the two breasts are in different sizes or shapes. A difference may occur between the shapes and sizes of the two breasts due to developmental disorders, breastfeeding, pregnancy or hormonal imbalance. Breast asymmetry occurs due to many different causes.

Newly developing differences may be caused by menstrual period or hormonal factors but such difference may also be caused by a serious factor such a breast cancer. Benign or malignant cysts developing in the breast can cause a deformation and asymmetry as well.

On the other hand, there are some women with inherently asymmetric breasts. The double organs in face and the body are considered to be asymmetrical if they show even slight differences. With the advancement of technology as well as the development of surgical and anesthesia techniques, today many options are available for women who want their two breasts to be more symmetrical.

Breast asymmetry operations change the structure and size of the breast, in accordance with the desire of the patient. When breast asymmetry is eliminated, breast augmentation or breast reduction procedures can be performed.
