This work covers a topic of considerable current interest, and presents many of the findings available to date. Workers at the forefront of research on hormone replacement therapy and the implications for the risk of breast cancer were invited to attend a special conference at The Royal Society of Medicine in London in September, 1991, where the latest findings were presented and the implications of this research was discussed. This book reviews various aspects of HRT and breast cancer, the physiology of the menopause, the current use of HRT in practice, osteoporosis and epidemiology, and it presents results from a range of European, American and Australian studies on the role of breast cancer and HRT, finishing with an overview of benefits, use and cost-effectiveness and a general summary.
