Breast Cancer



The mammogram is the most common breast cancer screening test. Learn about screening recommendations for breast cancer from the U.S. Preventive Services Task Force and the American Cancer Society and breast cancer screening services from the Johns Hopkins Breast Center. More information about mammograms is available in Spanish.

To schedule a screening mammogram, call 410-955-4100 or learn more about appointments at the Johns Hopkins Breast Center.

Risk Assessment/Genetic Testing

Some women have a greater risk of breast cancer than other women. Learning about your risk may help you and your doctor make decisions about prevention and screening.

To determine your breast cancer risk, use a risk assessment tool such as the National Cancer Institute Breast Cancer Risk Assessment Tool.

Do I have a hereditary risk for breast cancer based on my family history?

There are well-known genetic mutations within genes, called BRCA1 and BRCA2 that can greatly increase a woman’s chances of developing breast and ovarian cancer. Women with a family history of breast cancer may consider genetic counseling and possibly genetic testing.

Learn more about whether genetic testing for breast and ovarian cancer may be right for you through our Breast and Ovarian Surveillance Service (BOSS) or call 410-502-7082.

Diagnostic Services

What if my mammogram is abnormal?

After an abnormal mammogram, women often have a breast biopsy. A breast biopsy involves inserting a thin needle into the area of the breast that appears abnormal on the mammogram and removing tissue. The biopsied tissue is examined closely by a pathologist to determine if a woman has breast cancer. To schedule a breast biopsy at Johns Hopkins, call 410-955-7288.

Sometimes a second pathologist is asked to review the biopsy tissue to confirm the diagnosis. If you have already had a breast biopsy somewhere else and would like a Johns Hopkins pathologist to perform a second opinion pathology review, contact the Department of Pathology’s Second Opinion Service.
