SCENARIO

Lisa Thompson, a 52-year-old teacher, presents with a painless lump in her left breast that she noticed two weeks ago while showering. She describes the lump as firm, non-mobile, and about 2 cm in size.

She has no nipple discharge, skin dimpling, or axillary swelling, and she denies breast pain.

She has never had a mammogram, and she has a family history of breast cancer (mother diagnosed at age 58).

She is worried about cancer and asks what the next steps are.

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: What are your differential diagnoses for Lisa’s breast lump?

Lisa’s most likely diagnosis is breast cancer, given her age >50, firm non-tender lump, and family history of breast cancer. However, other conditions should be considered.

Key Differential Diagnoses:

  1. Breast Cancer (Most Likely) – Firm, non-mobile mass, painless, no overt signs but requires urgent triple assessment.
  2. Fibroadenoma – More common in younger women (<40 years), typically smooth, mobile, and well-defined.
  3. Breast Cyst – Fluctuant, often tender, may change with menstrual cycle.
  4. Fat Necrosis – Common after trauma, may mimic malignancy but often resolves spontaneously.
  5. Mastitis/Abscess – Associated with pain, erythema, fever, and often seen in lactating women.

Further assessment and triple testing (clinical exam, imaging, biopsy) are needed to confirm the diagnosis.


Q2: What red flags would indicate the need for urgent referral or further investigations?

Red flags requiring urgent referral:

  • Firm, non-tender, non-mobile lump.
  • Nipple changes (retraction, ulceration, discharge, Paget’s disease signs).
  • Skin dimpling or peau d’orange (lymphatic involvement).
  • Palpable axillary or supraclavicular lymph nodes.
  • Unexplained breast pain or asymmetry.

Initial Investigations:

  • Bilateral mammogram + ultrasound (first-line imaging).
  • Core needle biopsy (if suspicious features are present).
  • FNA of lymph nodes (if palpable).

Lisa requires an urgent breast clinic referral for triple assessment.


Q3: How would you manage Lisa’s condition?

1. Immediate Steps:

  • Urgent referral for triple assessment (clinical exam, imaging, biopsy).
  • Ensure Lisa understands the process and reasons for urgency.

2. Multidisciplinary Management (if cancer confirmed):

  • Surgical referral (lumpectomy vs mastectomy).
  • Oncology referral (chemotherapy, radiotherapy if indicated).
  • Genetic testing if high-risk family history.

3. Supportive Care:

  • Breast cancer nurse referral.
  • Psychosocial support – Encourage family involvement, counselling.
  • Discuss prognosis and treatment expectations.

Regular GP follow-up is essential to coordinate ongoing care and mental health support.


Q4: Lisa is anxious about the possibility of cancer. How would you counsel her?

  1. Acknowledge and Validate Her Anxiety
    • “I understand this is a worrying time, and it’s normal to feel anxious.”
  2. Explain the Next Steps Clearly
    • “We are arranging urgent tests to ensure we get a diagnosis quickly.”
    • “A breast lump can have many causes, and not all are cancerous.”
  3. Offer Emotional Support and Resources
    • “Would you like to bring a support person to your appointments?”
    • Refer to Breast Cancer Network Australia (BCNA) for guidance.
  4. Safety Netting and Follow-Up
    • Arrange timely follow-up to discuss results.
    • Ensure Lisa knows how to access support if she feels overwhelmed.

Effective counselling reduces distress and enhances trust in the management process.


Q5: What preventive strategies can Lisa implement to monitor her breast health?

  1. Routine Breast Cancer Screening:
    • Biennial mammograms (every 2 years for women aged 50–74 via BreastScreen Australia).
    • Consider annual screening if high-risk (e.g., strong family history).
  2. Self-Breast Awareness:
    • Encourage monthly self-examinations, looking for new lumps, nipple changes, or asymmetry.
  3. Lifestyle Modifications to Reduce Risk:
    • Limit alcohol to <4 standard drinks/week.
    • Maintain a healthy weight (BMI <25) to reduce oestrogen-related risks.
    • Regular physical activity (150 min/week).
    • Smoking cessation, if applicable.
  4. Family Risk Assessment & Genetic Testing:
    • Consider referral for BRCA testing if multiple family members affected.

Long-term breast health depends on regular screening, lifestyle modifications, and early detection.


SUMMARY OF A COMPETENT ANSWER

  • Comprehensive differential diagnosis, distinguishing benign from malignant breast conditions.
  • Identification of red flags, ensuring urgent referral and triple assessment.
  • Structured, evidence-based management plan, including specialist referral, imaging, and biopsy.
  • Clear patient-centred counselling, addressing Lisa’s anxiety and support needs.
  • Preventive strategies, including breast screening, lifestyle changes, and genetic risk assessment.

PITFALLS

  • Delaying referral, leading to missed early breast cancer diagnosis.
  • Failing to identify red flags, increasing risk of late-stage presentation.
  • Providing false reassurance, instead of explaining the need for further tests.
  • Not discussing psychological impact, leading to unaddressed patient distress.
  • Lack of structured follow-up, risking missed or delayed diagnosis.
