This lesion relates to columnar cell change with atypia and columnar cell hyperplasia with atypia."

This category includes atypical ductal hyperplasia, usual ductal hyperplasia, flat epithelial atypia, and ductal carcinoma in situ. There is an increased risk for subsequent development of invasive breast carcinoma."
