Top 20 hospitals by breast cancer diagnoses

Breast cancer is one of the most common types of cancer in the U.S., with the National Cancer Institute estimating the diagnosis of 310,720 new cases throughout 2024. Cancer’s many forms and potential sites of infection can make it hard to isolate data concerning a specific variation of the disease. However, using Definitive Healthcare’s Claim Analytics product, we are able to track which hospitals had the most patient visits for breast cancer.

We analyzed hospitals by patient visits for breast cancer in 2023, the last full year of data. This list shows the top hospitals with the highest percentage of total patient encounters for breast cancer.

How is breast cancer diagnosed?

Breast cancer is one of the most prevalent forms of cancer, accounting for roughly 30% of all diagnoses in women. But how exactly is it diagnosed?

The first step involves getting an x-ray of the breast in a procedure known as a mammogram. Most providers recommend that women start getting mammogram screenings at around age 40.

Most mammography procedures fall under one of two types: screening and diagnostic. Screening mammograms are preventative exams that are usually scheduled annually for women with no signs of cancer. Diagnostic mammograms involve a more thorough examination for individuals who demonstrate potential cancer symptoms. Both variations of the procedure often use a 3-D imaging system known as tomosynthesis in order to improve accuracy and decrease the level of false positives.

If breast cancer is detected, then doctors will perform a process known as staging to see if the cancer cells have spread throughout the breast or to other parts of the body. The level of spread outside the breast determines the stage that the cancer is currently in and the best path of treatment going forward.

A patient’s treatment plan may include medication prescribed by an oncologist, radiation therapy, chemotherapy, and/or surgery, depending on the stage and severity of the cancer.
