The association of DNA Repair with breast cancer risk in women. A comparative observational study.

Background: Previous studies have found a link between a low DNA repair capacity (DRC) level and increased cancer risk. Our aim was to assess the statistical association of DRC level and breast cancer (BC) using a case-control epidemiological study in a Hispanic community.

Methods: We conducted a comparative observational study to assess the validity of DRC in detecting BC in 824 women throughout Puerto Rico.
