Abstract: Ovarian cancer is the most lethal gynecological malignancy. It is the ninth most common cancer in women. 5 to 10% of ovarian cancers occur due to heritable risk. Hormone replacement therapy (HRT), reproductive factors such as age at menopause and infertility contribute to greater risk of ovarian cancer, whereas pregnancy, tubal ligation, and hysterectomy reduce risk. This research analysis was performed to analyse and extract various statistics associated with ovarian cancer. It was performed from the 2008 data obtained from The Nationwide Inpatient Sample (NIS). We used three main ASCII files from NIS: inpatient core file, disease severity measures file, and hospital weights file. From this data, we found 5,561 women with a primary diagnosis of ovarian cancer. Various comorbidities and many other factors related to ovarian cancer are analysed and studied. Their odds ratios are calculated. The results of each analysis are discussed.

Keywords: ovarian cancer; risk factors; SAS analysis; Nationwide Inpatient Sample; NIS; Healthcare Cost and Utilization Project; HCUP; odds ratio; comorbidity; percapita; biomedical informatics; bioinformatics.
