title: Gender of offspring and long-term maternal breast cancer risk.
abstract: Gender of offspring is influenced by maternal hormonal level during pregnancy, which is believed to influence the subsequent maternal breast cancer risk. However, analysing national birth and cancer registrations in a cohort of 998,499 women, we found no association between gender of offspring and subsequent breast cancer risk.
