Expression of claudin, paxillin and FRA-1 in non-nodular breast lesions in association with microcalcifications.

Context And Objective: The possible role of adhesion molecules in early breast carcinogenesis has been shown in the literature. We aimed to analyze early adhesion imbalances in non-nodular breast lesions and their association with precursor lesions, in order to ascertain whether these alterations exist and contribute towards early carcinogenesis.

Design And Setting: Retrospective cross-sectional study based on medical records at a private radiological clinic in São Paulo, Brazil.
