Breast Cancer Screening, Explained
May 4, 2026

Breast cancer screening can feel confusing — especially as new technologies are introduced and recommendations evolve. Understanding which screening methods are supported by long-term evidence, and how each is intended to be used, empowers you to make confident, informed decisions about your care.

What’s Proven

Mammography: The Foundation of Breast Cancer Screening

Mammography remains the only screening test proven to reduce breast cancer mortality. It helps detect cancer before symptoms appear and continues to be recommended as the first-line screening tool beginning at age 40 for most women.

• Backed by decades of clinical research
• Proven to reduce breast cancer deaths
• Often detects cancers years before they can be felt

When breast cancer is detected at its earliest stages, the 5-year survival rate is 99%. Early detection saves lives.

When Additional Imaging Is Recommended

Dense Breast Tissue & Supplemental Screening

Dense breast tissue is common and completely normal. However, dense tissue appears white on a mammogram — and so does cancer — which can make detection more challenging.

In some women, additional imaging may be recommended.

BREAST MRI
• Highly sensitive screening tool for higher-risk patients
• May detect additional cancers not seen on mammogram

BREAST ULTRASOUND
• Helpful in evaluating specific findings

These tools are designed to complement — not replace routine mammography.

What to Consider Before Replacing Mammography

Mammography remains the only screening test proven to reduce breast cancer mortality.

New imaging technologies continue to be introduced and studied. While some may provide additional information, no screening test has replaced mammography as the standard of care for routine screening.

BEFORE CHOOSING AN ALTERNATIVE, ASK:
• Is it FDA-cleared for use as a replacement for routine mammography — or only as a supplement?
• Has it demonstrated long-term reduction in breast cancer deaths?
• Is it supported by established screening guidelines?

While some facilities provide individual screening services, comprehensive breast imaging programs ensure that screening, advanced imaging, and expert interpretation are coordinated in one place. At CORA, this integrated approach helps provide clear answers and timely follow-up when additional imaging is needed.
