**5. Conclusions**

This study showed that aluminum chloride causes minimum-to-moderate hyperplastic (proliferative) intraductal cell proliferation and genotoxicity. Our results indicate that the BRCA1 product is not involved in the process of DNA damage repair and infer that the SCL11a2 product does not participate in aluminum transport under the proposed experimental conditions.
