In this review, we summarize the early history of PR research in breast cancer, debunk the myth that progesterone causes cancer, discuss recent discoveries in PR regulating cellular heterogeneity, attempt to reconcile theories that PR play “good” and “bad” role in tumorigenesis, and discuss new directions that may help elucidate the role of this puzzling hormone and its receptors. </p></abstract><trans-abstract xml:lang="ru"><p>История изучения прогестерона и прогестероновых рецепторов (ПР) при раке молочной железы сколь легендарна, столь и противоречива.
