This first volume of a two-volume set on prevention of cancer in the workplace is a teacher's guide designed to serve as a basis for lecture presentations and class discussions within the context of a formal course setting and structure. The course is organized into nine modules that can be taught using a lecture and discussion format in single instructional sessions of three hours each or in serial sessions. Each module contains objectives, lists of special terms, suggested teaching methods, special preparation needed, student assignments, information sheets, study questions, handouts, and references. The modules cover the following topics: an overview of cancer in the United States; major cancer theories; physiology, screening and treatment of cancer; carcinogens and cancer; testing carcinogens; carcinogens in the workplace; the impact of carcinogens on the environment; regulating carcinogens; and preventing cancer. A 23-page annotated bibliography, 13 pages of additional references, and suggestions for course-long assignments also are provided in the guide. (KC)
