This curriculum guide provides the teacher with a variety of suggestions intended to assist students in the seventh-, eighth-, and ninth-grades to develop proper attitudes regarding cancer and its prevention. In addition, learning experiences are suggested with the intent to teach students about the importance of early detection and treatment of cancer. Finally, teachers are provided with basic cancer information that will enable them to deal appropriately with student questions. Upon completion of the unit, the student will be able to (1) show how cancer is an aberrant process in cell growth for tissue development and replacement, (2) describe how cancer is a group of diseases representing an exaggerated response of the body's protective mechanism against internal and external irritants, (3) discuss why the cause of cancer is non-specific and can be attributed to identifiable combinations of genetic and environmental factors, (4) identify habits and hazards considered as causative or contributory factors in cancer development, (5) identify the common sites of cancer in human beings, (6) list services available for early detection of cancer growth, (7) describe what the individual can do for the early detection, prevention, and control of cancer, (8) give examples of cancer research efforts, and (9) develop a plan of personal action for cancer prevention and control. The text of the guide is divided into three columns per page, dealing with concepts, activities, and supplementary information for the teacher. A glossary of terms is included and seventeen appendixes of charts, graphs, and drawings expand on information contained in the text. (MB)
