with a similar shape on two views 
but does not fit the criteria of a mass: that is, 
it lacks convex outer borders and 
conspicuity. 
In contrast to global asymmetry, it occupies a volume 
of less than one quadrant of 
the breast and is of more concern. 
The frequency of finding focal asymmetry at screening 
mammography is less than 1%.

Valid for the following modalities: MG.</td></tr><tr><td style="white-space:nowrap">AsymmetryGlobal<a name="MGAbnormalityAsymmetryTypeCS-AsymmetryGlobal"> </a></td><td>Asymmetry global</td><td>Global asymmetry in breast tissue is a form of breast 
asymmetry where at least one 
quadrant of a breast has a larger amount of fibroglandular 
density than the corresponding 
area in the contralateral breast. 


Valid for the following modalities: MG.</td></tr><tr><td style="white-space:nowrap">DevelopingAsymmetry<a name="MGAbnormalityAsymmetryTypeCS-DevelopingAsymmetry"> </a></td><td>Developing Asymmetry</td><td>A developing asymmetry is a focal asymmetry that 
is new or increased in conspicuity 
compared with the previous mammogram. 
It is challenging to evaluate, as it often looks 
similar to fibroglandular tissue 
at mammography. 
A developing asymmetry should be viewed with suspicion 
because it is an uncommon 
manifestation of breast cancer.
