Breast Cancer Screenings

A mammogram takes images of the breast using low-dose X-rays. An annual mammogram—or screening mammogram—is one of the best tests for early detection of breast cancer. During the exam, the breast is compressed between two plates, allowing your care team to take clear pictures of your breast tissue.

Many of our breast imaging centers offer 3D mammography, also called digital breast tomosynthesis. This type of mammography is newer than traditional 2D mammography. It takes multiple images in an arc across the breast, providing a 3D view. Doctors may recommend 3D mammography for women with dense breasts.

You may have a breast MRI as part of your screening for breast cancer if you have a high risk of the condition or if you have dense breast tissue. However, an MRI of the breast is not recommended for those at an average risk. Magnetic resonance imaging uses magnets and radio waves to create images of the inside of your breast.

While less common than mammograms or a breast MRI for screening, you may have a breast ultrasound as part of your breast cancer tests. This imaging test uses sound waves to create images of the breast tissue. It often lets your care team look more closely at a lump or diagnose a non-cancerous cyst.

Research hasn’t shown strong benefits of routine breast exams in the early detection of breast cancer, so breast exams shouldn’t replace imaging tests as screenings. But they can help create awareness around the normal look and feel of your breasts.

• Clinical breast exam: A clinical breast exam allows a trained professional, such as a doctor or nurse, to check for any lumps and look for changes in the appearance of your breasts. These are often performed each year at your annual checkup.
• Self-breast exam: You can perform a breast self-exam monthly to check for breast lumps and changes in the shape, color, texture or appearance of your breasts and nipples. Do these self-exams around the same time every month. If you notice anything that isn’t normal for you, call your primary care provider or OBGYN.
