Introducing a new section to Breast Cancer Research: endocrinology and hormone therapy.

Endocrine therapy is increasingly understood as the conceptual basis for the future treatment and prevention of breast cancer. Endocrine agents have considerably changed the approach to targeted treatment during the past two decades, and select endocrine agents have advanced the goal of preventing breast cancer. Progress has occurred because of a vigorous interaction between laboratory scientists and the clinical trials community. Breast Cancer Research is launching a new section on endocrinology and hormone therapy in order to invigorate this exchange and challenge our readers with novel concepts that might result in enhanced survival in breast cancer.
