The cause of ovarian cancer is unknown, but there are a few risk factors that may increase your chances of getting it. Things like:
Older age: Ovarian cancer is more common in women 50 to 60 years old.
Genetics: You can inherit certain gene mutations that may give you a greater chance of having ovarian cancer.
Family history of ovarian cancer: If two or more close relatives have ovarian cancer, your chances may increase.
Estrogen hormone replacement therapy: The longer the duration and the larger the dose, the risk might be higher.
An early period and late menopause: Getting your period at a younger age and/or starting menopause at an older age might increase your risk.
