  1. aSingle-nucleotide polymorphisms (SNPs) selected from among the most significantly associated with breast cancer in the genome-wide association studies by Easton and colleagues [7], Hunter and colleagues [8], and Stacey and colleagues [9] described further in the 'Single-nucleotide polymorphism selection' section of Materials and methods. bRate ratio adjusted for age at diagnosis of first primary tumor and counter-matching weight. cP value with 1 degree of freedom for the association of per-allele SNP genotype and contralateral breast cancer (CBC) risk. dFor rs13387402, A is not the minor allele in this study population. CI, confidence interval; UBC, unilateral breast cancer.
