This volume presents the knowledge, views, and experiences of ex­ perts in the fields of health care that are particularly important to women. Not all of the authors agree on all of the issues, but all share the same concerns about women's health and recognize the impor­ tance of providing information to enable women to become active par­ ticipants in the health care partnership. The idea for the book evolved from our own work in the field of women's health care. The positive responses we received to several papers and presentations based on our experiences and addressed to patients, physicians, and other health care professionals indicated that there is a growing need for open discussion of women's health care issues as well as a need for developing and implementing new and better ways of dealing with these issues. We were further motivated by the repeated failure of the health care community to integrate new insights and information (that frequently contradict older, established beliefs and practices) into current health planning, education, and practice.
