Definition
A morphologic spectrum of lesions that arise in the terminal ductal lobular units of the breast parenchyma. These lesions are characterized by the presence of columnar epithelial cells that line dilated terminal ductal lobular units. Cytological and architectural atypia may be absent or minimal, or significant enough to raise the possibility of atypical ductal hyperplasia or ductal carcinoma in situ. Columnar cell lesions are frequently found in breast biopsies but their biologic significance is not known.

Names
CancerIndex is a research and information platform. It does not diagnose and does not recommend treatment.
Key figures
Each figure carries its unit, period and source; ranks link to "Why this rank?".
No registry-level ancestor: burden figures are published for the mutually exclusive top-level site groups only, and this entity does not descend from one. Global figures (IARC / GLOBOCAN) stay under license review and SEER awaits credentials.
