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 its 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.

Using the Definitive Healthcare Atlas All-Payor Claims product, we’ve compiled a list of the top 25 U.S. hospitals with the most diagnoses for ovarian cancer in 2022. This list shows the top hospitals by their percentage of the total patient encounters for ovarian cancer and represents diagnoses for the full calendar year of 2022.

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:

  • Epithelial carcinoma is the most common type of ovarian cancer and occurs when cancer cells start growing in the outer layer of cells in the ovaries.
  • Germ cell cancer develops in egg cells inside the ovaries and can usually be treated without harming fertility.
  • Stromal cell cancer is the rarest type of ovarian cancer and starts in the connective tissue that holds the ovaries together.

How is ovarian cancer diagnosed? 

There are many different tests that are performed to screen for ovarian cancer, but a tissue biopsy is the only thing that can definitively confirm an ovarian cancer diagnosis. Initial suspected ovarian cancer diagnoses are often based on common symptoms, including bloating, fatigue, weight loss, abdominal distention, pelvic pain, and feeling full quickly.

Unfortunately, by the time most patients with ovarian cancer see a doctor, 70% to 80% are already at stage three or four as the early symptoms of ovarian cancer can easily be confused with other conditions.

Who treats ovarian cancer?

Once a diagnosis of ovarian cancer is confirmed, a patient may be referred to a care team that includes multiple types of doctors depending on the patient’s treatment options. The most common provider who treats patients with ovarian cancer is known as a gynecologic oncologist. These providers are specially trained to perform surgery for ovarian cancer, the most common type of treatment. They are also often the ones providing chemotherapy or other medicines to patients with ovarian cancer.

In addition, a patient might also interact with a radiation oncologist, a doctor who specializes in radiation therapy as well as a medical oncologist who specializes in administering chemotherapy and other cancer-related medicines.
