Gender of offspring and long-term maternal breast cancer risk.
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.
