Ovarian cancer is the seventh most common cancer in women worldwide (18 most common cancer overall), with 239,000 new cases diagnosed in 2012.
Ovarian cancer often has no symptoms at the early stages, so the disease is generally advanced when it is diagnosed. The 5-year survival rate (which compares the 5-year survival of people with the cancer to the survival of others at the same age who do not have cancer) ranges from approximately 30 to 50 per cent.
The Continuous Update Project Panel judged that there was convincing evidence that adult attained height increases the risk of ovarian cancer and that body fatness (marked by BMI) is probably a risk of this cancer.
Preventability Estimates using the new findings from the Continuous Update Project show that maintaining a healthy weight can prevent about 5 percent of cases of ovarian cancer in the US.
The countries with the top 20 highest incidence of ovarian cancer in 2012 are given in the table below.
- Fiji had the highest rate of ovarian cancer, followed by Latvia and Bulgaria.
- About 58% of ovarian cancer cases occurred in less developed countries.
- The highest incidence of ovarian cancer was in Europe and Northern America; and the lowest incidence in Africa and Asia.

In 2012 the rate of ovarian cancer was more than two times higher in Central and Eastern Europe compared with Eastern Asia.
The 5-year prevalence of women globally living with ovarian cancer is 22.6 per 100,000 (estimated from incidence and observed survival by cancer and age group).
