According to this hypothesis, an early FFTP [first full-term pregnancy] would provide the greatest protection against breast cancer by drastically reducing, early on, the presence of undifferentiated and hence vulnerable breast cells, thereby decreasing the risk of subsequent transformation ... Other types of pregnancies, however, might increase the risk of breast cancer. If a woman's first pregnancy resulted in a first trimester abortion, the dramatic rise in undifferentiated cells that takes place during the first trimester would not be followed by the marked differentiation occurring during the second and third trimesters. The consequent sharp increase in the number of vulnerable cells would thus elevate breast cancer risk.
根据这一假设，早期的首次足月妊娠（FFTP）通过在早期大幅减少未分化因而易患癌的乳腺细胞数量，从而降低后续细胞转化的风险，能为预防乳腺癌提供最大程度的保护……然而，其他类型的妊娠可能会增加患乳腺癌的风险。如果一名女性的首次妊娠以孕早期流产告终，那么在孕早期未分化细胞数量的急剧增加之后，不会出现孕中期和孕晚期发生的显著分化。因此，脆弱细胞数量的大幅增加会提高患乳腺癌的风险。
