Breast

Breast densities have the  following significance:

• Increased basal markings could be due to breast tissue, especially from lactating breasts.

  • Evaluate significance of basal changes in lateral view.

• Asymmetry of breast  can be normal, but can also suggest a disease process.

• A missing breast indicates surgical resection for breast cancer  (most likely reason) and can suggest etiology for the observed lung lesion.

  • Hyperlucency of bases is expected when one breast is missing.
