Following this Introduction, Chapter 2 presents the remarks of the morning plenary speakers in order of appearance, Chapter 3 presents the speakers and discussion from the afternoon group discussions, and Chapter 4 concludes the symposium with the summing up and further discussion from the rapporteurs and audience. All the presentations and discussions were edited for facile reading and to add graphic material from slides used in the presentations in the form of figures where essential. In this less formal forum than a Board report, much interesting information and analysis and many provocative ideas and suggestions could emerge during the day from the experts, officials, and opinion leaders who participated. This record of the day should provide continuing food for thought and ideas for actions in support of cancer prevention and early detection.
