Letter to the editor: Ethnic and age differences in rightleft breast asymmetry in a large population-based screening population

摘要

To the Editor, We read with great interest the recent article by Hudson and colleagues in the November issue of British Journal of Radiology entitled “Ethnic and age differences in right-left breast asymmetry in a large population-based screening population.”1 The authors should be commended for the largest population-based analysis of breast volume using an automated assessment of mammography in healthy females. Our biggest conclusion of this important study is that breast volume asymmetry is common among various age and ethnic populations and not an indication of underlying pathology. The question of breast asymmetry and an association with breast cancer is challenging as there are several ways to measure breast asymmetry and multiple confounding factors that can contribute to differences from one breast to the other.
