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 five-year survival rate (which compares the five-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 per cent 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.

About 58% of ovarian cancer cases occurred in less developed countries.
