Anisomastia is a medical condition in which there is a severe asymmetry or unequalness in the size of the breasts, generally related to a difference in volume. [1] In other words, when one of the breasts is much larger than the other. [2] In contrast to anisomastia, a slight asymmetry of the breasts is common. [1]
Fluctuating asymmetry (FA) is often considered to be the product of developmental stress and instability, caused by both genetic and environmental stressors. The notion that FA is a result of genetic and environmental factors is supported by Waddington's notion of canalisation, which implies that FA is a measure of the genome's ability to successfully buffer development to achieve a normal ...
Breast development is commonly asymmetric and one or both breasts may be small. This condition may be a congenital defect associated with underlying abnormalities of the pectoral muscle (as in Poland's syndrome [ 2 ] ), related to trauma (typically surgery or radiotherapy ) or it may be a more subjective aesthetic description.
The physical signs and changes associated with breast cancer aren't limited to the breast tissue.
The indication is an excess breast weight that exceeds approximately 3% of the total body weight. [3] There are varying definitions of what is considered to be excessive breast tissue, that is the expected breast tissue plus extraordinary breast tissue, ranging from as little as 0.6 kilograms (1.3 lb) up to 2.5 kilograms (5.5 lb) with most physicians defining macromastia as excessive tissue of ...

The breast is positioned, affixed to, and supported upon the chest wall, while its shape is established and maintained by the skin envelope. [32] [33] In most women, one breast is slightly larger than the other. [19] More obvious and persistent asymmetry in breast size occurs in up to 25% of women. [34]
Similarly, over-dissection of the pocket can weaken the medial breast tissue and cause implant migration towards the midline, resulting in symmastia. [9] Implant size and placement are also important factors that can contribute to symmastia. Larger implants have a higher risk of causing symmastia due to their increased weight and volume.
