How is breast cancer diagnosed?

A breast cancer diagnosis is performed using breast imaging after suspicious symptoms, like a breast lump, or an abnormal mammogram are reported. Types of imaging used include 3D mammograms, ultrasounds, and MRI. After imaging tests, a breast biopsy is used to confirm the findings.

We look at breast tissue from every angle before delivering a diagnosis. If you have had imaging performed somewhere else, our specialized radiologists interpret your previous scans and order additional imaging when necessary. The tools we use to diagnose breast cancer include the following.

Identifying the factors that shape a breast cancer diagnosis

Receiving a breast cancer diagnosis can be overwhelming, but understanding the specific characteristics of the cancer is the first step toward effective treatment. We look beyond the initial discovery to evaluate several key considerations, such as hormone status and genetic risk. This thorough approach allows us to tailor a care plan that is as unique as your own biology.

Breast cancer second opinions at Penn Medicine

Penn Medicine specialists welcome seeing second opinions for breast cancer diagnoses, offering specific diagnostic imaging tools, tests, and procedures that are often more modern than what is available at other healthcare facilities. These advancements help us diagnose your specific type of cancer and guide us in developing your personalized treatment plan. To schedule a second opinion, call us at 800-789-PENN (7366) or contact a breast oncology nurse navigator.

If you were diagnosed at another health care center, additional diagnostic tests may be necessary. In advance, we may request items including pathology slides, copies of recent imaging results, and previous health records. Prepare any questions you may want answered ahead of the appointment. Plan to have a friend, family member, or support person come with you to your appointment to help record information and be of support throughout the process.
