Abstract Summary

Study of 574 California teachers suggests full-term pregnancy may reduce non-Hodgkin lymphoma risk in women, particularly after one pregnancy and at younger maternal ages. The protective effect appears linked to pregnancy hormones like progesterone rather than breastfeeding, offering new insights into how reproductive factors influence immune-related cancer development.

Why Brain? 🧠

Full-term pregnancy, especially at younger ages, may reduce non-Hodgkin lymphoma risk in women, possibly through hormonal effects on immune function, suggesting pregnancy hormones may protect against this cancer.
