Breast Cancer Research and Treatment provides the surgeon radiotherapist medical oncologist endocrinologist epidemiologist immunologist or cell biologist investigating problems in breast cancer a single forum for communication. The journal creates a 'market place' for breast cancer topics which cuts across all the usual lines of disciplines providing a site for presenting pertinent investigations and for discussing critical questions relevant to the entire field. It seeks to develop a new focus and new perspectives for all those concerned with breast cancer. Oncology is undoubtedly the most rapidly growing subspecialty in the field of medicine and breast cancer is one of the most serious problems of oncology. It is the leading cause of death of women in many countries and is truly a multidisiplinary problem without geographic restrictions. Yet this very multidisciplinary aspect accounts for breast cancer literature appearing in any of the dozens of existing medical journals. None of these journals provides a focus on the unique problems of breast cancer. There has been no convenient arena for the discussion and resolution of ongoing controversies in breast cancer treatment or for the consideration of thoughtful speculation and comments on current work. Breast Cancer Research and Treatment aims to fill this need. Each issue contains several articles dealing with original laboratory investigations and articles dealing with clinical studies. There are sections devoted to invited review articles pro and con discussions of controversial subjects book reviews meeting reports and editorials. Panel discussions are presented which bring together experts to consider important topics. There is a section for letters to the editor which provides for a lively exchange of opinions on previously published articles or other topics of interest. There is also an opportunity to publish the proceedings of special workshops symposia etc. devoted to breast cancer. All manuscripts are peer reviewed by a distinguished group of advisory editors from many countries covering all of the various disciplines of breast cancer.
