Number of New Cases and Deaths per 100,000: The number of new cases of ovarian cancer was 11.6 per 100,000 women per year. The number of deaths was 7.2 per 100,000 women per year. These rates are age-adjusted and based on 2011-2015 cases and deaths.
Lifetime Risk of Developing Cancer: Approximately 1.3 percent of women will be diagnosed with ovarian cancer at some point during their lifetime, based on 2013-2015 data.
Prevalence of This Cancer: In 2015, there were an estimated 224,940 women living with ovarian cancer in the United States.
How Many People Survive 5 Years Or More after Being Diagnosed with Ovarian Cancer?
Relative survival statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.
Based on data from SEER 18 2008-2014. Gray figures represent those who have died from ovarian cancer. Green figures represent those who have survived 5 years or more.
Survival by Stage
Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. The earlier ovarian cancer is caught, the better chance a person has of surviving five years after being diagnosed. For ovarian cancer, 14.9% are diagnosed at the local stage. The 5-year survival for localized ovarian cancer is 92.3%.

How Common Is This Cancer?
Compared to other cancers, ovarian cancer is relatively rare.
|Rank||Common Types of Cancer||Estimated New
|1.||Breast Cancer (Female)||266,120||40,920|
|2.||Lung and Bronchus Cancer||234,030||154,050|
|5.||Melanoma of the Skin||91,270||9,320|
|8.||Kidney and Renal Pelvis Cancer||65,340||14,970|
Ovarian cancer represents 1.3% of all new cancer cases in the U.S.
In 2018, it is estimated that there will be 22,240 new cases of ovarian cancer and an estimated 14,070 people will die of this disease.
Who Gets This Cancer?
Ovarian cancer is rare. Women with a family history of ovarian cancer have an increased risk for the disease. The number of new cases of ovarian cancer was 11.6 per 100,000 women per year based on 2011-2015 cases.

Who Dies From This Cancer?
For ovarian cancer, death rates generally increase with age. Ovarian cancer is the thirteenth leading cause of cancer death in the United States. The number of deaths was 7.2 per 100,000 women per year based on 2011-2015.

Trends in Rates
Changes Over Time
Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.
Using statistical models for analysis, rates for new ovarian cancer cases have been falling on average 1.5% each year over the last 10 years. Death rates have been falling on average 2.3% each year over 2006-2015. 5-year survival trends are shown below.

More About This Cancer
Cancer and the Ovary
Figure: Anatomy of the female reproductive system; drawing shows the uterus, myometrium (muscular outer layer of the uterus), endometrium (inner lining of the uterus), ovaries, fallopian tubes, cervix, and vagina.
The ovaries are a pair of organs in the female reproductive system. They are in the pelvis, one on each side of the uterus (the hollow, pear-shaped organ where a fetus grows). Each ovary is about the size and shape of an almond. The ovaries make eggs and female hormones (chemicals that control the way certain cells or organs work).

These stat facts focus on population statistics that are based on the U.S. population. Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. To see tailored statistics, browse the SEER Cancer Statistics Review. To see statistics for a specific state, go to the State Cancer Profiles.
The statistics presented in these stat facts are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. In some cases, different year spans may be used. Estimates for the current year are based on past data.
Cancer is a complex topic. There is a wide range of information available. These stat facts do not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although links are provided to information in many of these areas.
