Ovarian, Fallopian Tube, and Peritoneal Cancer: Statistics

Approved by the Cancer.Net Editorial Board, 02/2022

ON THIS PAGE: You will find information about the number of people 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 19,880 people in the United States will be diagnosed with ovarian cancer. The vast majority of these cases (90%) are high-grade serous ovarian cancers (HGSC), which begin in a fallopian tube. Worldwide, an estimated 313,959 people were diagnosed with ovarian cancer in 2020.

From 1990 to the mid-2010s, the number of new ovarian cancer cases decreased by 1% to 2% each year. The drop in the incidence rates accelerated to 3% from 2014 to 2018. This positive trend may be due to a higher use of oral contraceptives and the reduced use of hormone therapy for menopause in the 2000s. Ovarian cancer is more common in White women than in Black women.

It is estimated that 12,810 deaths from ovarian cancer will occur in the United States this year. In 2020, an estimated 207,252 people worldwide died from ovarian cancer. 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 death rate declined by around 2% during the 2000s and early 2010s. From 2015 to 2019, the decrease in death rates accelerated to 3% annually. This decline in death rate is mostly due to fewer cases and advances in treatment.

The 5-year survival rate tells you what percent of people live at least 5 years after cancer is found. Percent means how many out of 100. The 5-year survival rate for people with all types of ovarian, fallopian tube, and peritoneal cancers in the United States is 49%.

However, the survival rate varies widely depending on the person's age, as well as the stage, cell type, and grade of the cancer. For example, the 5-year survival rate for women younger than 65 is 61%, compared with 33% for women 65 and older. Survival rates are also improved when debulking surgery is performed by a gynecologic oncologist instead of a gynecologist or general surgeon (see Types of Treatment).

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 93%. Approximately 19% of women with epithelial 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 75%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 30%. At least half of people are diagnosed at this stage.

It is important to remember that statistics on the survival rates for people with ovarian, fallopian tube, and peritoneal cancer are an estimate. The estimate comes from annual data based on the number of people with these cancers in the United States. Also, experts measure the survival statistics every 5 years. This means the estimate may not reflect the results of advancements in how ovarian, fallopian tube, and peritoneal cancer are diagnosed or treated from the last 5 years. Talk with your doctor if you have any questions about this information. Learn more about understanding statistics.
