Ovarian, Fallopian Tube, and Peritoneal Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 08/2016

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 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 22,440 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 begins in a fallopian tube.

It is estimated that 14,080 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 46%.  

However, the rate varies widely depending on age of the woman, as well as the stage and grade of the cancer. About half of women diagnosed with ovarian cancer and fallopian tube cancer are 63 years or older. The 5-year survival rate for women younger than 45 is 77%. For women 75 and older, the survival rate is 20%.

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 92%. 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 questions about this information.
