Approach to Asymmetry

  • Radhakrishna Selvi


Breasts are generally symmetric structures with similar densities and architecture (Fig. 7.1). However, asymmetric densities are a frequent finding on mammography and have been reported to occur in 3 % of mammograms. Asymmetric density represents an area of tissue with fibroglandular structures that is more extensive in one breast relative to the corresponding region in contralateral breast. Once asymmetric density is identified on a mammogram, its nature has to be determined.
