Presence or absence of a breast symptom or prior abnormal imaging finding.
Side by side
Screening mammography is routine imaging in asymptomatic patients at recommended intervals.
Diagnostic mammography is targeted evaluation for symptoms, palpable abnormalities, or abnormal screening results.
Population-level early detection seeks stage shift before symptoms develop.
Problem-focused imaging characterizes a known clinical or radiographic abnormality to guide next procedures.
Screening typically uses standard bilateral views without immediate focused compression unless callback is needed.
Diagnostic studies add spot compression or magnification views and can include same-visit targeted ultrasound for palpable findings.
The trap
Ordering routine screening protocol for a new palpable mass delays definitive workup. Symptomatic patients require diagnostic imaging protocol.
The repair move
Next best step: order diagnostic mammography with targeted breast ultrasound for the palpable area, then proceed to image-guided biopsy if suspicious features persist.

Show answer and explanation
Answer: B. Screening mammography. Asymptomatic patients follow routine screening mammography schedules.
Why the other choices are tempting
- A. Incorrect because diagnostic mammography is reserved for symptoms or abnormal prior imaging.
- C. Incorrect because MRI is not universal first-line screening for average-risk patients.
- D. Incorrect because guideline-based imaging is recommended in appropriate age groups.
- E. Incorrect because whole-body CT is not a breast screening strategy.
