  Asymmetryhttp://hl7.org/fhir/us/breast-radiology/CodeSystem/AsymmetryAbnormalityTypeCSAsymmetry

Breast asymmetry refers to when one breast is a different size or shape than the other.

  AsymmetryFocalhttp://hl7.org/fhir/us/breast-radiology/CodeSystem/AsymmetryAbnormalityTypeCSAsymmetry focal

Focal asymmetry is visible as a confined asymmetry 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%. [pubs.rsna.org]

  AsymmetryGlobalhttp://hl7.org/fhir/us/breast-radiology/CodeSystem/AsymmetryAbnormalityTypeCSAsymmetry global

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.

  DevelopingAsymmetryhttp://hl7.org/fhir/us/breast-radiology/CodeSystem/AsymmetryAbnormalityTypeCSDeveloping Asymmetry

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. [pubs.rsna.org]

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
