Breast Health Awareness: Know Your Body

Breast Cancer Awareness month aims to save lives by increasing knowledge, promoting early detection, and supporting research efforts to combat breast cancer. 

What You Need to Know About Mammograms and Screening

1 in 8 women in the United States will be diagnosed with breast cancer in their lifetime, but early detection saves lives. Understanding breast health, knowing the facts about mammograms, and following the latest screening guidelines can help you take charge of your health.

Regular mammography screening beginning at age 40 significantly reduces breast cancer deaths and the need for more aggressive therapies, with the greatest benefit seen in early-stage detection. Unfortunately, misinformation regarding mammography is associated with later detection and worse clinical outcomes.

Common Myths About Mammograms

Myth 1: Mammograms are only for older women.

Fact: Leading health organizations now recommend that women start mammograms at age 40. Early screening can catch cancer before symptoms appear, when it’s most treatable. 

Myth 2: If I don’t have a family history, I don’t need screening.

Fact: Most women diagnosed with breast cancer have no family history. Age is the biggest risk factor, so regular screening is important for all women, not just those with a family history.

Myth 3: Mammograms are dangerous because of radiation.

Fact: The amount of radiation in a mammogram is very low - approximately equivalent to 2 months of natural background radiation exposure in the US from the environment. The benefits of early detection far outweigh the minimal risk from radiation.

Myth 4: Mammograms always find cancer.

Fact: While mammograms are the best tool for early detection, they are not perfect. Some cancers may not show up, especially in women with dense breasts. That’s why knowing your own body and reporting changes is important.

Breast Cancer Screening Guidelines: What’s Right for You?

Annual screening mammography starting at age 40 is recommended for average-risk women (no family history and no known genetic mutations). Screening should always be a shared decision making process with your provider. 

If you have a higher risk—such as a strong family history, certain genetic mutations (like BRCA1/2), or had chest radiation at a young age—your doctor may recommend starting screening earlier and may add breast ultrasound or MRI to your routine.

Breast Self-Awareness: Know What’s Normal for You

While routine self-exams are no longer recommended for everyone, it’s important to be familiar with how your breasts normally look and feel. If you notice changes—like a new lump, skin changes, or nipple discharge—contact your healthcare provider promptly.

What About Dense Breasts?

Dense breast tissue is common and can make it harder for mammograms to spot cancer. If you have dense breasts, your doctor may discuss ultrasound or MRI on top of mammography. Ultrasound alone has NOT been shown to reduce breast cancer deaths nor has it been shown to be as effective as mammography for early detection.

Takeaway Tips for Breast Health

• Start talking to your doctor about breast cancer risk now.

• Follow recommended screening guidelines based on your age and risk.

• Be aware of changes in your breasts and report them right away.

• Don’t let myths or fear keep you from getting screened—early detection saves lives.

Breast cancer screening is not one-size-fits-all. The best plan is the one that fits your personal risk and preferences. Talk with your healthcare provider to make informed choices about your breast health.
