The epidemiology of ovarian cysts is unclear due to the lack of consistent reporting and a high likelihood of spontaneous resolution. Worldwide, about 7% of women have an ovarian cyst at some point in their lives. One study based on autopsy findings in post-menopausal women (mean age 73 years), showed that about 15% of post-menopausal women have adnexal cysts. Prevalence of benign masses among post-menopausal women was 0.8% to 1.8% in a screening study. Most US prevalence data indicate a range among the general population of 3% to 15%. A large European screening trial revealed a 21.2% incidence of ovarian cysts among healthy post-menopausal women. Approximately 1.2% of women in the US will be diagnosed with ovarian cancer during their lifetime, based on National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) data from 2015 to 2017. In 2020, an estimated 21,750 new cases of ovarian cancer will be reported, 48.6% (SEER 18 2010-2016) of whom can expect to survive 5 years or more after diagnosis.
