Abstract

Background A diagnosis of a second primary breast cancer (‘bilateral breast cancer’) occurs in between 2-11% of women affected by breast cancer in the general population, but is increased in frequency in women with a family history of breast cancer. We investigated whether the common genomic variants described in breast cancer GWAS studies were determinants of the risk of bilateral breast cancer and compared the effect to that of family history.

Highlights

  • A diagnosis of a second primary breast cancer (‘bilateral breast cancer’) occurs in between 2-11% of women affected by breast cancer in the general population, but is increased in frequency in women with a family history of breast cancer

  • Common genomic variants associated with breast cancer predict the risk of second primary breast cancer diagnosis

  • We investigated whether the common genomic variants described in breast cancer GWAS studies were determinants of the risk of bilateral breast cancer and compared the effect to that of family history
