Number of New Cases and Deaths per 100,000: The number of new cases of ovary cancer was 12.1 per 100,000 women per year. The number of deaths was 7.7 per 100,000 women per year. These rates are age-adjusted and based on 2008-2012 cases and deaths.

Lifetime Risk of Developing Cancer: Approximately 1.3 percent of women will be diagnosed with ovary cancer at some point during their lifetime, based on 2010-2012 data.

Prevalence of This Cancer: In 2012, there were an estimated 192,446 women living with ovary cancer in the United States.

Survival StatisticsShow More

How Many People Survive 5 Years Or More after Being Diagnosed with Ovary Cancer?

Relative survivalExternal Web Site Policy 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.

45.6%

Based on data from SEER 18 2005-2011. Gray figures represent those who have died from ovary cancer. Green figures represent those who have survived 5 years or more.

Additional Information

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 ovary cancer is caught, the better chance a person has of surviving five years after being diagnosed. For ovary cancer, 14.7% are diagnosed at the local stage. The 5-year survival for localized ovary cancer is 92.1%.

Ovary cancer represents 1.3% of all new cancer cases in the U.S.

1.3%

In 2015, it is estimated that there will be 21,290 new cases of ovary cancer and an estimated 14,180 people will die of this disease.

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 ovary cancer was 12.1 per 100,000 women per year based on 2008-2012 cases.

Percent of New Cases by Age Group: Ovary Cancer
1.3% under 20; 3.8% 20-34; 7.2% 35-44; 18.4% 45-54; 23.8% 55-64; 21.1% 65-74; 16.2% 75-84; 8.1% 85 and older

Ovary cancer is most frequently diagnosed among women aged 55-64.

For ovarian cancer, death rates generally increase with age. Ovary cancer is the twelfth leading cause of cancer death in the United States. The number of deaths was 7.7 per 100,000 women per year based on 2008-2012.

Percent of Deaths by Age Group: Ovary Cancer
0.1% under 20; 0.7% 20-34; 2.4% 35-44; 10.5% 45-54; 21.3% 55-64; 25.4% 65-74; 25.4% 75-84; 14.2% 85 and older

The percent of ovary cancer deaths is highest among women aged 65-74.

Trends in RatesShow More

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 ovary cancer cases have been falling on average 1.1% each year over the last 10 years. Death rates have not changed significantly over 2002-2012. 5-year survival trends are shown below the figure.

Cancer and the Ovary

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.

Click to enlarge.

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).

The statistics presented in this factsheet 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. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas.
