Triple Assessment of the Breast

• Bailey and Love's Short Practice of Surgery, 28th ed., p. 937
• Robbins, Cotran & Kumar Pathologic Basis of Disease, p. 962

Component 1 - Clinical Assessment

History

• Duration and change in size of the lump
• Relationship to the menstrual cycle (cyclical vs. non-cyclical)
• Associated pain, nipple discharge (character, colour, unilateral/bilateral)
• Skin changes (redness, dimpling, peau d'orange)
• Family history of breast or ovarian cancer
• Hormonal history (OCP, HRT, menarche, menopause, pregnancies)
• Prior breast biopsies or surgery

Clinical Examination Technique

• Asymmetry or change in breast contour
• Skin dimpling or tethering
• Nipple retraction or inversion (new vs. long-standing)
• Peau d'orange (dermal lymphatic oedema - a sign of locally advanced cancer)
• Erythema or ulceration

• Use the pad of three fingers (index, middle, ring)
• Apply the dial of a clock method - systematic examination from the periphery inward in a radial pattern (Figure 58.3 shows this technique)
• Axillary, supraclavicular, and infraclavicular nodes must also be palpated

Clinical breast examination: (a) patient supine for palpation, (b) pad of three fingers, (c) clock-dial method - Bailey & Love, 28th ed.

Interpretation of the Lump

Component 2 - Radiological Imaging

A. Ultrasonography (USG)

• Women under 40 years (dense breast tissue makes mammography hard to interpret)
• Evaluation of a palpable mass in any age group
• Characterising cystic vs. solid lesions

Ultrasound of a complicated cyst - anechoic lesion with floating internal debris (BI-RADS 2). Bailey & Love, 28th ed.

B. Mammography

• Mediolateral-oblique (MLO)
• Craniocaudal (CC)

• Spiculated or irregular mass with ill-defined margins
• Clustered pleomorphic microcalcifications (may indicate DCIS)
• Architectural distortion
• Asymmetric density
• Skin thickening or nipple retraction
• Lymphadenopathy (in advanced cases)

• Digital mammography - superior for younger women and dense breasts
• Digital Breast Tomosynthesis (DBT/3D mammography) - multi-sectional images reducing tissue overlap; shown to improve cancer detection rate (STORM-2 trial, 9,672 patients)
• Contrast-enhanced mammography (CEM) - IV iodine contrast exploiting tumour neovascularity; approaches MRI accuracy
• CAD/AI - software-assisted detection to improve sensitivity
• Sabiston Textbook of Surgery, p. 1874-1880

C. MRI Breast

• High-risk screening (BRCA1/2 carriers, strong family history)
• Extent assessment of known malignancy before surgery (multifocal/multicentric disease)
• Assessment of response to neoadjuvant chemotherapy
• Dense breasts where mammography and USG are inconclusive
• Occult primary with axillary metastasis
• Discordant clinical and imaging findings
• Implant integrity evaluation

The BI-RADS Scoring System (Breast Imaging Reporting and Data System)

Biopsy is required for definitive diagnosis in lesions with BI-RADS 4 or 5.

Component 3 - Tissue Sampling (Pathology)

A. Fine Needle Aspiration Cytology (FNAC)

• Quick, inexpensive, minimally invasive
• Suitable for palpable lumps, superficial nodes, thyroid
• Results available within hours

• Cannot distinguish invasive from non-invasive (in situ) carcinoma
• Cannot determine receptor status (ER, PR, HER2) reliably
• High false-negative rate if sample is inadequate
• Operator dependent

B. Core Needle Biopsy (CNB / Tru-cut)

• Histological (architectural) diagnosis
• Can distinguish DCIS from invasive carcinoma
• Allows receptor status (ER, PR, HER2) and Ki-67 assessment
• Supports neoadjuvant treatment planning
• Now the standard of care for tissue diagnosis

Core biopsy specimen allows histology, receptor and genomic analysis, and can identify patients best suited for neoadjuvant systemic treatment.

• Fischer's Mastery of Surgery, 8th ed.; Schwartz's Principles of Surgery, 11th ed.

C. Vacuum-Assisted Biopsy (VAB) and Open Excision Biopsy

• VAB (Mammotome) used for stereotactic biopsy of microcalcifications and small non-palpable lesions; single needle insertion with multiple cores
• Open excision biopsy (wire- or seed-localised) reserved when percutaneous biopsy is non-diagnostic, or to excise B3 lesions

Interpretation and Concordance

Concordant Benign (C2/B2 + BI-RADS 2-3 + benign clinical features):

• Reassurance and routine follow-up
• No surgery required

Concordant Malignant (C5/B5 + BI-RADS 4-5 + suspicious clinical features):

• Proceed to definitive surgical treatment
• Neoadjuvant chemotherapy if indicated

Discordant Results:

1. Repeat biopsy (preferably core needle)
2. Multidisciplinary team (MDT) discussion
3. Consider open excision biopsy if still unresolved

The combination of careful clinical assessment, imaging, and biopsy (core biopsy and/or FNAC) identifies >99.5% of breast malignancies in patients with symptomatic breast disease.

Clinical Indications for Triple Assessment

• Palpable breast lump (any age)
• Nipple discharge (especially unilateral, bloody, spontaneous)
• Nipple retraction (new onset)
• Skin changes (peau d'orange, dimpling, erythema)
• Nodular breast (without pain)
• Mammographic abnormality detected on screening
• Follow-up of previously treated breast cancer
• During pregnancy/lactation with a new breast mass
• Male breast with gynaecomastia needing exclusion of carcinoma
