Breast cancers that arise sporadically, rather than through inheritance of certain genes, likely start with defects of DNA repair mechanisms that allow environmentally triggered mutations to accumulate, according to researchers. The findings indicate that chemotherapy drugs that target DNA in later-stage cancers could be an effective treatment for the earliest of breast tumors.
