Understanding Breast Cancer Screening and Diagnostic Mammography

Understanding Breast Cancer Screening and Diagnostic Mammography

Mon Sep 28 2026

Breast cancer screening can help physicians identify breast changes that may require further evaluation. Understanding the difference between screening mammography and diagnostic mammography can help patients know what to expect when they schedule breast imaging.

For people researching breast cancer screening in Houston, the type of imaging used depends on their individual circumstances, symptoms, risk factors, and a physician's recommendations.

What Is Breast Cancer Screening?

Screening mammography is generally performed when a patient does not have breast symptoms and is undergoing routine screening.

The purpose is to look for breast changes that may require further evaluation.

Screening recommendations can vary based on factors such as age, personal history, family history, risk factors, and guidance from a physician.

Screening Mammography vs. Diagnostic Mammography

Screening mammography and diagnostic mammography have different purposes.

Screening mammography is used for routine breast cancer screening when a patient does not have known symptoms.

Diagnostic mammography may be recommended when a patient has a symptom, an abnormal screening result, or another concern that requires additional evaluation.

The TOPS Comprehensive Breast Center offers both screening mammography and diagnostic mammography.

What Is 3D Mammography?

3D mammography, also called digital breast tomosynthesis, captures multiple images of breast tissue from different angles.

These images provide physicians with a series of views that can be reviewed when evaluating breast tissue.

TOPS offers both 3D and 2D mammography as part of its breast imaging services.

When May Additional Imaging Be Recommended?

A physician may discuss breast imaging results and explain whether additional evaluation or testing is recommended.

Sometimes a mammogram requires additional evaluation.

A physician may recommend another imaging study when a screening image shows an area that requires closer examination or when a patient has a symptom that needs further assessment.

Depending on the situation, additional testing may include breast ultrasound or another diagnostic procedure.

The TOPS Comprehensive Breast Center offers breast ultrasound, contrast-enhanced mammography, ultrasound-guided biopsy, stereotactic needle biopsy, and other diagnostic services.

What to Expect During Mammography

During mammography, the breast is positioned between two plates and briefly compressed while images are obtained.

Patients may experience pressure or temporary discomfort during compression.

Before the examination, patients should follow the imaging center's instructions and provide relevant medical information.

Questions to Ask Your Physician

Patients may want to ask:

  • Which type of mammography is appropriate for me?
  • Is this appointment for screening or diagnostic imaging?
  • Do I have risk factors that affect my screening plan?
  • Should I have additional imaging?
  • When should I expect my results?
  • What happens if the imaging identifies an area that needs further evaluation?

Preparing questions in advance can help patients better understand their screening plan.

Breast cancer screening is individualized. Physicians consider a patient's circumstances when recommending appropriate imaging and follow-up.
