The unique physiologic changes that occur within the breast secondary to the hormonal changes of pregnancy and lactation result in increased breast volume and increased water content, with associated palpable nodularity, firmness, and increased parenchymal density. Large lesional size (>10 mm), ill-defined margin, and irregular outlines are associated with malignancy. Pathology The gross pathology of an RS/CSL is similar to that of a small invasive carcinoma.
