Top 25 hospitals by ovarian cancer diagnoses

Ovarian cancer is the fifth most common type of cancer among women, accounting for more deaths than any other cancer of the female reproductive system, in the United States.

A woman's risk of getting ovarian cancer during her lifetime is about 1 in 78. Ovarian cancer can be difficult to detect in the early stages due to the small size of the ovaries and location deep within the abdomen. Additionally, early detection can be difficult because the initial symptoms are similar to other conditions. Only 20% of all ovarian cancer cases are discovered in the early stages. Ovarian cancer often goes undetected until it has spread within the pelvis and abdomen.

Because September is ovarian cancer awareness month, we’ve compiled a list of the top 25 U.S. hospitals that diagnosed the greatest number of ovarian cancer cases in 2021, using claims data from multiple medical claims clearinghouses.

As is common with oncology treatments, patients visit multiple specialists during ovarian cancer treatment, including oncologists and radiologists. Using data from the Definitive Healthcare ClaimsMx product, we analyzed hospitals by patient visits for ovarian cancer in 2021. This list shows the top hospitals by their percent of the total patient encounters for ovarian cancer.

What are the different types of ovarian cancer?

There are three main types of ovarian cancer that differ based on the location of the cancerous cells.

The most common type is epithelial carcinoma, whereby the cancer cells start growing in the outer layer of cells in the ovaries. The second type is germ cell cancer which typically appears in girls and teenagers. Germ cell cancer develops in egg cells inside the ovaries and can usually be treated without harming fertility. The third and most rare type of ovarian cancer is stromal cell cancer, which starts in the connective tissue that holds the ovaries together.
