oa South African Medical Journal - Study of malignant neoplastic disease in primitive communities : with special reference to South Africa



Some of the difficulties inherent in studying the incidence of cancer among primitive peoples are outlined. Methods are descriptionbed which will probably assess some of these difficulties. It is unlikely that very accurate statistics on cancer can be obtained in the Bantu, but only a good estimate. It is hoped to obtain such an estimate by a survey organized by the South African Institute for Medical Research with assistance from the National Cancer Institute of America. The use of proportional rates is discussed and their strict limitation emphasized. Information obtained by the use of proportional rates at Baragwanath non-European Hospital is summarized. The unique position of South Africa for cancer demographic studies is stressed.
