A 62-year-old female presents with a painless, hard, irregular 2.5 cm breast mass in the upper outer quadrant with overlying skin dimpling and axillary lymphadenopathy. What is the standard diagnostic approach to evaluate this lesion?

Answer and explanation

Correct answer: A. Triple assessment (clinical examination, imaging, and core needle biopsy)

  1. Step 1: The gold standard protocol for evaluating any suspicious breast lump is the Triple Assessment, which comprises: (1) clinical breast examination, (2) radiological imaging (bilateral mammography and ultrasound), and (3) histological evaluation via core needle biopsy.
  2. Step 2: High concordance across all three modalities yields a diagnostic accuracy approaching 99%.
Answer
Triple assessment (clinical examination, imaging, and core needle biopsy).
Why not the others: 'Observation for two menstrual cycles' is inappropriate for postmenopausal women and causes unacceptable oncological delay; 'Serum CA 15-3' is a monitoring marker for metastatic disease, not a diagnostic screening tool; 'Excisional biopsy directly' violates surgical staging protocols and risks incomplete margins.
