abstract

  • PROBLEM: This study investigated how pregnancy might protect against breast cancer. METHOD OF STUDY: A critical review of the literature was done.RESULTS/CONCLUSIONS: Support for an active role in pregnancy immunizing against breast cancer comes from case studies demonstrating a reciprocal correlation between pregnancy and breast cancer as well as recent experiments supporting the fetal antigen hypothesis that confirms the presence of a tumor‐specific antigen, MUC1, on both fetal and breast cancer tissues. Multiparous women also generate anti‐MUC1 major histocompatibility complex‐restricted cytotoxic T cell cytolytic activity against MUC1‐bearing tumor cell lines. Careful investigation of the fetal antigen hypothesis and tolerogenic mechanisms may lead to effective vaccination protocols against breast cancer and other cancers.
