A Cohort Study of Hereditary Ovarian Cancer Risk Prediction Models and Pathogenesis Exploration

This study is developing a better model to predict the risk of hereditary ovarian cancer in women who have been diagnosed with epithelial ovarian cancer and carry known genetic mutations. The goal is to improve genetic counseling and guide screening recommendations for patients and their family members. **You may be eligible if...** - You are 18 or older - You have been diagnosed with epithelial ovarian cancer (the most common type) - You have had genetic testing that identified a pathogenic or likely pathogenic mutation - Your diagnosis has been confirmed by a pathologist **You may NOT be eligible if...** - Your ovarian cancer is confirmed to be a non-epithelial type (such as germ cell or stromal tumors) - You have not had genetic testing performed Talk to your doctor to see if this trial is right for you.
