2. Breast composition
• A= Entirely fatty
• B= Scattered áreas of
fibroglandular density
• C= Heterogeneosly dense
• D= Extremely dense
Important findings
• Masses
• Assymetry
• Architectural distorsion
• Calcifications
• Associated features

3. Screening
History of cancer (Breast, ovary)
Previous studies
Contraceptives (Estrogens)
Palpable mass

6. Breast Composition

7. Architectural
Distorsion

8. Assymetries: visible on only one projection, mostly caused by superimposition of
normal breast tissue.
Focal asymmetry: Visible on two projections, hence a real finding rather than
superposition.
This has to be differentiated from a mass.
Global asymmetry: Consisting of an asymmetry over at least one quarter of the
breast and is usually a normal variant.
Developing asymmetry: New, larger and more conspicuous than on a previous
examination.

10. Calcifications
