Breast health is an important part of preventive healthcare. Clinical breast exams, mammograms, and awareness of changes in your breasts can all play a role in recognizing potential problems and deciding when additional evaluation may be needed.

A clinical breast exam and a mammogram are not the same thing. A clinical exam involves a healthcare professional examining the breasts and surrounding areas, while a mammogram uses X-rays to create images of breast tissue.

For women at average risk, current U.S. Preventive Services Task Force guidance recommends screening mammography every two years from ages 40 through 74. Individual recommendations can differ when someone has symptoms or a higher-than-average risk.

Understanding how these approaches differ can help you have a more informed conversation about your breast health.

What Is a Clinical Breast Exam?

A clinical breast exam is a physical examination performed by a healthcare professional.

During the exam, the provider may examine and feel the breast tissue and areas around the breasts, including the underarm region, looking for changes that may require further evaluation.

The CDC describes a clinical breast exam as an examination in which a doctor or nurse uses their hands to feel for breast lumps or other changes.

Depending on your circumstances, a healthcare professional may also ask about:

• Previous breast problems

• Family history of breast cancer

• Previous breast imaging

• Breast pain

• New lumps or thickening

• Nipple changes or discharge

• Changes in breast size or appearance

• Other symptoms you have noticed

A clinical exam provides information through physical examination, but it does not create an image of the breast.

What Is a Mammogram?

A mammogram is an X-ray examination of the breast.

During mammography, specialized equipment creates images of breast tissue that can be reviewed for findings that may require additional evaluation.

Mammograms can identify some breast cancers before a lump becomes large enough to feel or before other symptoms develop. The CDC identifies mammography as the primary breast cancer screening method for most women in the recommended screening age range.

Mammography may be used in two broad situations:

Screening Mammogram

A screening mammogram is performed when a person does not have a specific breast symptom or known abnormality being investigated.

Its purpose is to look for potential signs of breast cancer before symptoms develop.

Diagnostic Mammogram

A diagnostic mammogram is used when there is a specific concern that needs further evaluation, such as a breast lump, certain changes seen on a previous mammogram, or other concerning symptoms.

The imaging approach may be different from routine screening because the healthcare team is evaluating a particular concern.

Clinical Breast Exam vs. Mammogram

Although both relate to breast health, they provide different types of information.

These approaches should not automatically be treated as interchangeable.

Your healthcare professional can determine which evaluations are appropriate based on your age, symptoms, risk factors, and screening history.

When Should Women Start Mammograms?

For women at average risk, the USPSTF currently recommends screening mammography every two years from age 40 through age 74. This recommendation applies to women and other people assigned female at birth in this age range who are at average risk.

The recommendation does not apply in the same way to people with certain high-risk circumstances, including known high-risk genetic syndromes, previous breast cancer, or previous high-risk breast lesions.

Other professional organizations may recommend different screening schedules. For example, the American College of Radiology and Society of Breast Imaging recommend annual screening beginning at age 40 for women at average risk.

Because recommendations can differ, your healthcare professional can help you understand which schedule applies to your individual situation.

How Often Should You Have a Mammogram?

Under the current USPSTF recommendation, women ages 40 to 74 at average risk should have a screening mammogram every two years.

However, your personal screening schedule may be different if you have:

• A personal history of breast cancer

• A known genetic risk associated with breast cancer

• A strong family history

• Previous high-risk breast lesions

• Previous abnormal breast imaging

• Other factors that increase breast cancer risk

Women age 75 and older should discuss screening with their healthcare professional because the USPSTF considers the current evidence insufficient to make a general recommendation for or against screening in this age group.

Does a Mammogram Replace a Clinical Breast Exam?

Not necessarily.

A mammogram and clinical examination provide different information.

A mammogram can identify certain abnormalities within breast tissue, including findings that may not be detectable by touch. A clinical examination allows a healthcare professional to evaluate a physical finding and consider your symptoms and health history.

It is also important to understand that a normal mammogram does not mean that every breast concern can be ignored.

If you notice a new or concerning breast change, tell your healthcare professional even if your most recent mammogram was normal.

What Breast Changes Should You Report?

Knowing what is normal for your breasts can help you recognize changes that deserve attention.

Contact a healthcare professional if you notice a new or persistent change such as:

• A new lump or mass

• Thickening in part of the breast

• A change in breast size or shape

• Skin dimpling or an unusual skin change

• Nipple inversion that is new

• Unexplained nipple discharge

• Persistent breast or nipple pain

• A change in the appearance of the breast

These symptoms do not automatically mean breast cancer.

Many breast changes have causes other than cancer. However, a new or persistent change should be evaluated rather than diagnosed based on symptoms alone.

What Is Breast Self-Awareness?

Breast self-awareness means becoming familiar with the normal appearance and feel of your breasts so that you can recognize changes.

The CDC encourages women to be familiar with how their breasts look and feel and to tell a healthcare professional about changes such as lumps, pain, or changes in size.

Breast self-awareness is different from relying on a formal breast self-examination as a replacement for recommended screening.

You do not need to repeatedly examine your breasts according to a rigid routine. Instead, pay attention to changes that are unusual for you and bring persistent or concerning findings to a healthcare professional.

What Happens During a Mammogram?

A mammogram is performed using specialized X-ray equipment.

During the procedure, each breast is positioned on the mammography equipment so images can be obtained. Compression is used briefly while the images are taken.

Some people experience pressure or discomfort during compression. The experience varies between individuals.

If you are scheduling a mammogram, it can help to tell the mammography technologist if you are experiencing breast pain or have a particular area of concern.

After the images are obtained, a qualified professional reviews them and determines whether additional imaging or follow-up is needed.

What Happens After an Abnormal Mammogram?

An abnormal mammogram does not automatically mean that you have breast cancer.

A screening mammogram may identify an area that needs a closer look. Depending on the finding, the next step may include additional mammographic views, breast ultrasound, or another form of evaluation.

If a biopsy is recommended, tissue may be collected and examined to determine what is causing the abnormal finding.

The important point is that an abnormal screening result is a reason for follow-up, not a diagnosis by itself.

The USPSTF emphasizes that people with abnormal screening mammography findings should receive appropriate follow-up evaluation and additional testing when indicated.

What If You Have Dense Breasts?

Breast density describes how much fibroglandular tissue appears on a mammogram compared with fatty tissue.

Dense breasts are common, and breast density can affect how mammograms are interpreted.

The USPSTF currently states that there is insufficient evidence to recommend for or against supplemental screening with ultrasound or MRI for women with dense breasts who have an otherwise negative mammogram.

If you are told that you have dense breasts, ask your healthcare professional:

• What does my breast density mean?

• Does my overall risk profile change my screening plan?

• Is additional imaging appropriate for me?

• When should my next mammogram be scheduled?

Your breast density should be considered alongside your overall risk rather than viewed in isolation.

Who May Need a Different Breast Screening Plan?

Average-risk screening recommendations may not apply to everyone.

Your healthcare professional may recommend a different approach if you have factors such as:

• A known BRCA1 or BRCA2 genetic variation

• Another genetic syndrome associated with breast cancer risk

• A strong family history

• Previous breast cancer

• A previous high-risk breast lesion

• A history of high-dose radiation to the chest at a young age

The USPSTF's 2024 recommendation specifically excludes certain high-risk groups from its average-risk screening recommendation.

If you have a significant family history or another risk factor, mention it before deciding on a screening schedule.

Why Include Breast Health in Preventive Care?

Breast health is one component of comprehensive women's healthcare.

A preventive visit can provide an opportunity to discuss your breast history, risk factors, symptoms, and recommended screening. It also gives you a chance to ask questions about when and where to have mammography.

For women looking for broader preventive care, women's primary care services in California can provide an opportunity to discuss breast health and other healthcare needs with a qualified provider.

Keeping your screening history organized can also make future appointments easier. If you have previous mammogram reports or know where earlier imaging was performed, let your healthcare team know.

When Should You Contact a Healthcare Professional?

Do not wait for your next routine mammogram if you discover a new breast change.

Contact a healthcare professional if you notice a new lump, persistent pain, nipple changes, unusual discharge, skin changes, or another breast finding that concerns you.

The appropriate next step may be a clinical examination, diagnostic imaging, or another evaluation depending on what you are experiencing.

Screening mammography is designed for people without a specific breast symptom. A new symptom may require a different diagnostic approach.

How Can You Prepare for Your Breast Health Appointment?

Before your appointment, consider making a note of:

• The date of your most recent mammogram

• Any previous abnormal imaging results

• Your family history of breast cancer

• Any breast symptoms you have noticed

• Previous breast biopsies or procedures

• Questions about your screening schedule

You can also ask your healthcare professional to explain why a particular screening interval or imaging test is being recommended.

Having this information available can make your breast health discussion more productive.

Breast Health Is About More Than One Test

Clinical breast exams and mammograms serve different purposes. A clinical examination allows a healthcare professional to assess physical changes, while mammography provides breast imaging that can identify some abnormalities before they can be felt.

For women at average risk, the current USPSTF recommendation is mammography every two years from ages 40 through 74. Other professional organizations recommend different schedules, and people with higher-risk circumstances may need a different screening strategy.

The most appropriate approach depends on your age, health history, risk factors, symptoms, and previous screening results.

Conclusion

Taking care of your breast health means knowing the role of different types of evaluation.

A clinical breast exam provides a hands-on assessment by a healthcare professional, while a mammogram uses X-ray imaging to look for breast abnormalities. Neither should be automatically treated as a substitute for the other when a particular evaluation is medically appropriate.

For average-risk women, current USPSTF guidance recommends screening mammography every two years between ages 40 and 74. People with symptoms or higher-than-average risk may need a different approach.

Most importantly, do not ignore a new or persistent breast change simply because your last mammogram was normal. Bring concerns to a healthcare professional so the appropriate evaluation can be determined.

FAQ Section

1. What is the difference between a clinical breast exam and a mammogram?

A clinical breast exam is a physical examination performed by a healthcare professional who looks at and feels the breasts and surrounding areas. A mammogram uses X-rays to create images of breast tissue. The two evaluations provide different types of information.

2. At what age should women start getting mammograms?

For women at average risk, the USPSTF recommends screening mammography every two years beginning at age 40 and continuing through age 74. Other medical organizations may recommend different schedules, so discuss your screening plan with your healthcare professional.

3. Does a mammogram replace a clinical breast exam?

Not necessarily. Mammography and clinical examination have different purposes. A healthcare professional may recommend an examination when you have a breast symptom or physical change even if you have recently had a normal mammogram.

4. What should I do if I find a breast lump?

Tell a healthcare professional about any new or persistent breast lump. A lump does not automatically mean cancer, but it should be evaluated appropriately. Depending on your situation, the evaluation may include a clinical examination and diagnostic imaging.

5. What happens if my mammogram is abnormal?

An abnormal screening mammogram does not automatically mean that you have breast cancer. Your healthcare team may recommend additional imaging or other evaluation to determine the cause of the finding.

6. Do women with dense breasts need additional screening?

Not necessarily. The USPSTF currently finds insufficient evidence to recommend for or against supplemental ultrasound or MRI for women with dense breasts and an otherwise negative mammogram. Your individual risk factors should be considered when deciding whether additional imaging is appropriate.
