Breast cancer remains a disease of considerable public health importance worldwide, with over 800,000 new cases diagnosed globally each year. Considerable energy is currently being spent by researchers to further our understanding of this complex disease, however, keeping up with all of the new data is a real challenge given the sheer volume of information that becomes available on a daily basis. The purpose of this book would be to provide a comprehensive review of breast cancer epidemiology, covering the topics of disease burden, etiology, risk factors, prevention, early detection/screening, treatment, and outcomes. The book would be a single comprehensive source of the most recent information on breast cancer epidemiology, and it would serve as a valuable resource for breast cancer researchers across disciplines regardless of what stage of their career they are in. To the knowledge of the editor, no such resource is currently available.
