Breast Examination and Triple Test Protocol

Clinical Introduction and Patient Rapport

  • Initial Interaction Sequence: Establish a professional connection with the patient immediately upon entry.

    • Introduce yourself: "Hi, my name is Amir."

    • Verify patient identity: Ask for the patient's name (e.g., "Nice to meet you, Julie").

Informed Consent and Examination Overview

  • Purpose of Examination: Clearly explain why the procedure is necessary. For example: "I've been asked to examine your breasts today because I want to feel the breast lump you're having and look at its characteristics to have a better understanding of it."

  • Procedural Steps: Outline exactly what will happen to manage patient expectations:

    • Visual inspection of both breasts.

    • Gentle palpation of the entire breast tissue and specifically the lump.

    • Examination of the axilla (armpits).

  • Exposure and Privacy:

    • Full exposure of both breasts is required.

    • Offer time and privacy for the patient to undress.

    • Provide a sheet/gown for the patient to cover themselves until the examination begins.

  • Patient Autonomy (The Stop Signal): Explicitly state that the patient can stop the examination at any time. This serves as the "stop signal."

  • Standard Questions: Confirm if the patient is happy to proceed and wash hands before physical contact.

The Role of the Chaperone in Sensitive Examinations

  • The Chaperone Offer: Offering a chaperone is a critical competency.

    • Verbatim phrasing: "I can offer a chaperone to be with us during the examination. Would you like me to have one?"

  • Myths and Proper Conduct:

    • A chaperone is NOT mandatory if the patient refuses; in such cases, document the refusal and proceed.

    • Do not simply assume the examiner is the chaperone. You must offer to find a neutral third party (e.g., a nurse).

    • The concept is the offer of the chaperone, not forcing one on the patient.

Equipment and Mannequin Handling Protocol

  • Use of Gloves:

    • Gloves are generally not a "key point" or "critical fail" point in breast examinations unless specifically instructed by signs or examiners.

    • In cases like testicular or bimanual GYN examinations, the examiner may explicitly command you to wear gloves, or signs will be posted by hand sanitizer stations.

    • Breast examinations typically do not strictly require gloves in a clinical testing environment unless local protocol dictates otherwise.

  • Mannequin Interaction:

    • NEVER lift, move, or stand up the mannequin (e.g., trying to sit it up for inspection).

    • The mannequin should remain in its provided position on the bed.

    • Check for a sheet; identify if the mannequin is covered. Ask the role-player: "Is it okay if I just remove the sheet of the breast?"

Systematic Inspection and Running Commentary

  • General Appearance: Begin with a comment on the patient's general state (e.g., "On general appearance, I cannot see any cachexia").

  • The Three Positions of Inspection: To avoid repetition and save time, instruct the role-player in three positions while observing the mannequin.

    1. Hands neutral on the lap.

    2. Hands on the waist and pushing in: This contracts the pectoral muscles to reveal tethering.

    3. Hands behind the head, pushing elbows back and leaning forward.

  • Inspection Checklist (The Three S's/C's):

    • Skin: Check for dimpling, puckering, asymmetry, visible masses, or Peau d'orange (orange peel appearance).

    • Nipple: Check for retraction, redness, ulceration, or discharge.

    • Nipple Squeeze: Ask the patient (Julie) to squeeze the nipple to check for discharge. If the role-player says "do it yourself," perform the squeeze on the mannequin and report findings to the examiner: "There is no discharge."

Systematic Palpation Procedure

  • Temperature: Assess local temperature using the dorsal part of the fingers on both sides.

  • Patient Positioning: Simulate or request the patient to lie down with the hand behind their head on the side being examined.

  • The Sequence of Palpation:

    • Always ask the patient to confirm which side the lump is on.

    • Start with the normal side: This prevents forgetting the healthy breast and establishes a baseline.

    • Use a systematic pattern (spiral or vertical strip), covering from the midaxillary line and including the axillary tail (Tail of Spence), ensuring you cross the nipple.

Evaluation of a Breast Lump

  • Critical Characteristics for Commentary: When a lump is found, you must detail the following to the examiner:

    • Size: Estimate in centimeters (e.g., 2−3 cm2-3\,cm).

    • Location: Specify the quadrant (e.g., "Upper outer quadrant").

    • Tenderness: Ask the patient: "Is it painful when I touch the lump?"

    • Consistency: Describe the feel (e.g., rubbery, soft, or stony hard).

    • Surface and Border: Note if the surface is smooth and if the borders are regular or irregular.

    • Mobility: Assess if the lump moves freely or is fixed.

    • Pectoral Fixation: Ask the patient to squeeze their chest muscles and check if the lump moves with the muscle contraction.

Lymph Node Assessment

  • Axillary Groups: Examine five specific groups in the armpit:

    1. Apical group: High in the axilla.

    2. Central group: Against the chest wall.

    3. Anterior (Pectoral) group: Along the lower border of the pectoralis minor.

    4. Posterior (Subscapular) group: Along the lateral border of the scapula.

    5. Humeral (Lateral) group: Along the upper humerus/axillary vein.

  • Additional Nodes: Check the Supraclavicular and Cervical lymph nodes (behind the patient) if time permits.

  • Clinical Tip: If the mannequin lacks an axilla, simulate the palpation in the empty space where the axilla would be while providing running commentary.

Diagnosis and Differential Diagnosis

  • Case 1: The Single Lump

    • Fibroadenoma (Benign): Characterized as a rubbery, extremely mobile (the "breast mouse"), smooth lump with regular borders.

    • Breast Cancer (Malignant): Characterized as a stony hard, fixed, non-mobile lump with irregular borders.

  • Case 2: Bilateral Pain (Fibrocystic Changes)

    • Presentation: Bilateral breast pain (cyclical mastalgia) with multiple lumps (1010 to 2020 cysts).

    • Characteristics: Lumps are typically mobile, cystic, or rubbery.

  • General Differentials: Breast cyst, breast abscess, fat necrosis, and lipoma.

The Triple Test for Investigation

  • Every breast lump requires the Triple Test. Do not explain every detail immediately if short on time; list the steps first.

    1. Clinical Examination: (Already performed).

    2. Imaging:

      • Patients aged < 40: Breast Ultrasound.

      • Patients aged ≥40\ge 40: Breast Ultrasound and Mammogram.

    3. Pathology/Biopsy:

      • Fine Needle Aspiration (FNA): Used for cystic components/fluid aspiration.

      • Core Biopsy: A thicker needle used to take a tissue sample from solid lumps for microscopic analysis to determine if the tissue is benign or malignant.

Questions & Discussion

  • Question: Do we need the Triple Test for fibrocystic changes since they often seem benign?

  • Response: Yes. Even in fibrocystic changes, the Triple Test is required because one cyst might be larger, have solid components, or have a thick, irregular wall that could be malignant.

  • Question: How do I describe a mannequin's consistency?

  • Response: Always describe what you actually feel. Most mannequins are latex and feel rubbery; don't just say "soft" because you memorized a benign diagnosis if the physical model feels different.

  • Question: What if I can't find the lump in the exam?

  • Response: Be honest. Tell the patient: "I didn't find the lump today, Jane, but the possibilities are still…" and proceed with the differential diagnosis.
