Ovarian, Fallopian Tube, and Peritoneal Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 10/2017

ON THIS PAGE: You will find information about the number of women who are diagnosed with ovarian, fallopian tube, and peritoneal cancer each year. You will also read general information about surviving these diseases. Remember, survival rates depend on several factors. Use the menu to see other pages.

This year, an estimated 22,240 women in the United States will be diagnosed with ovarian cancer, and the vast majority of these are high-grade serous ovarian cancers (HGSC), which begin in a fallopian tube. Ovarian cancer accounts for 2.5% of cancers in women and 5% of deaths from cancer. That is because 4 out of 5 patients are diagnosed when the disease is at an advanced, less curable stage.

Older women and white women have the highest risk of the disease. About half of women diagnosed with ovarian and fallopian tube cancer are 63 or older.

It is estimated that 14,070 deaths from this disease will occur this year. Combined, cancer of the ovaries, fallopian tubes, and peritoneum are the fifth most common cause of cancer-related death in women in the United States.

The 5-year survival rate tells you what percent of women live at least 5 years after cancer is found. Percent means how many out of 100. The 5-year survival rate for women with all types of ovarian and fallopian tube cancer is 47%.  

However, the rate varies widely depending on age and ethnicity of the woman, as well as the stage and grade of the cancer. The 5-year survival rate for white women younger than 65 is 60% compared to 29% for those 65 and older. The survival rates for black women of the same ages are lower. Those younger than 65 have a 51% survival rate, while those 65 and older have a 22% survival rate.

If ovarian and fallopian tube cancers are diagnosed and treated before they spread outside the ovaries and tubes, the general 5-year survival rate is about 93%. Approximately 15% of women with ovarian and fallopian tube cancer are diagnosed at this stage. If the cancer has spread to surrounding tissues or organs, the 5-year survival rate is 73%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 29%. Approximately 60% of women are diagnosed at this stage.

It is important to remember that statistics on the survival rates for women with ovarian, fallopian tube, and peritoneal cancer are an estimate. The estimate comes from annual data based on the number of women with these cancers in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Women should talk with their doctor if they have any questions about this information.
