An evaluation is made of the hypothesis of Woods et al. (1) that the number of full-term pregnancies constitutes a factor of growth acceleration in breast cancer. Our results confirm, at least in part, the effect of parity on age at diagnosis of breast cancer. Patients with two or more children were significantly younger at the time of diagnosis than were those with none or one child. Age at first birth and duration of lactation do not seem to be, in this analysis, confounding factors for the observed association.
对伍兹等人（1）提出的足月妊娠数构成乳腺癌生长加速因素这一假说进行了评估。我们的结果至少部分证实了产次对乳腺癌诊断年龄的影响。有两个或更多孩子的患者在诊断时的年龄明显低于没有孩子或只有一个孩子的患者。在该分析中，初产年龄和哺乳期似乎并非所观察到的关联的混杂因素。
