An epidemiologic study of ovarian cancer. Part 1: Reproductive and social factors

This study was undertaken to investigate the risk factors of ovarian cancer. A retrospective analysis was used in this study where 52 ovarian cancer cases and an equal number of a control group were obtained from the Western region of Saudi Arabia. Analysis of data showed that cases and controls did not significantly differ in any of the studied social factors, marital status, social class, and family history of cancer ovary. However, when reproductive factors were considered, the mean values of parity and number of abortions, but not age at first birth. Were found to differ significantly between cases and controls.
