SOAP Note: 25-Year-Old Female with Non-Cyclical Left Breast Pain
Subjective
Chief Complaint: Left breast pain, non-cyclical
History of Present Illness:
- Pain characteristics: Focal, unilateral left breast pain without relation to menstrual cycle
- Location: Precise localization of pain (document exact quadrant/area - subareolar, lower inner breast, or other specific location) 1
- Duration and pattern: Onset, duration, whether constant or intermittent, any exacerbating factors (cold weather, exercise)
- Associated symptoms: Absence of skin changes (erythema, dimpling, retraction), nipple changes (discharge, scaling), palpable masses, or systemic symptoms (fever, warmth) 2
Breast Health History:
- Last mammogram: N/A (patient age 25)
- Breast self-examination practices
- Previous breast biopsies or surgeries: None documented
- Hormonal medications: Oral contraceptives, hormone therapy, or infertility treatments 1
- Other medications: Specifically SSRIs or other drugs that may cause mastalgia 1
Family History:
- Critical detail: Document breast and ovarian cancer in first-degree AND second-degree relatives on BOTH maternal and paternal sides going back 3 generations 3, 4
- Age at diagnosis of affected relatives
- Type of breast cancer (if known)
- Consider genetic counseling referral criteria
Allergies:
- Penicillin allergy: Document specific reaction type (rash, anaphylaxis, GI symptoms, headache, or family history only) 5
- Timing of reaction relative to penicillin exposure
- Critical distinction: True IgE-mediated reaction versus non-allergic adverse effect 5
Social History:
- Smoking status (associated with duct ectasia and periductal inflammation) 1
- Physical activity level
- Obstetric history, breast-feeding history 1
Review of Systems:
- Chest wall pain, musculoskeletal symptoms
- Cardiac, pulmonary, or GI symptoms that could represent referred pain 1
Objective
Vital Signs: Within normal limits
Physical Examination:
Visual Inspection (patient seated, hands on hips contracting pectoralis muscles): 2
- Breast symmetry and contour
- Skin changes: erythema, dimpling, retraction absent
- Nipple changes: scaling, inversion, discharge absent
- No visible masses or deformities
Palpation (patient supine with ipsilateral arm raised): 2
- Left breast: Focal tenderness at [specific location], no discrete masses palpable
- Pain reproducible on palpation: Yes/No
- Right breast: Non-tender, no masses
- Lymph nodes: Axillary, supraclavicular, infraclavicular nodes non-palpable bilaterally
- Chest wall examination: No costochondral tenderness, no chest wall muscle tenderness
Assessment
25-year-old female with focal, non-cyclical left breast pain and significant family history of breast cancer, penicillin allergy documented.
Primary Problem: Non-cyclical mastalgia, left breast
- Non-cyclical breast pain accounts for 25% of breast pain cases, is predominantly inflammatory rather than hormonal, and requires additional evaluation to exclude underlying benign or malignant lesions even without additional signs 1
- Risk stratification: Family history of breast cancer elevates baseline risk and warrants heightened vigilance 3, 4
- While breast cancer rarely presents as isolated pain, non-cyclical focal pain has been associated with underlying pathology in some cases 1
Differential Diagnosis:
- Benign breast disease (duct ectasia, cyst, fibroadenoma)
- Musculoskeletal/chest wall pain (costochondritis, muscle strain)
- Breast cancer (low probability but must exclude given family history)
- Medication-related mastalgia
- Referred pain from extramammary source
Plan
Diagnostic Imaging: Breast ultrasound is the appropriate initial imaging modality for this 25-year-old patient with focal, non-cyclical breast pain 6. Mammography is not indicated at age 25 unless ultrasound demonstrates suspicious findings requiring further characterization.
Rationale: ACR Appropriateness Criteria recommend ultrasound for women <30 years with clinically significant (focal and non-cyclical) breast pain 6. This avoids radiation exposure while effectively evaluating for cysts, solid masses, or other structural abnormalities.
Family History Management:
- Genetic counseling referral: Assess whether family history meets USPSTF criteria for genetic counseling (approximately 1.4 million US women meet these criteria) 7
- Document detailed 3-generation pedigree at this visit 3, 4
- Discuss potential need for earlier/enhanced screening if high-risk criteria met
Penicillin Allergy Assessment:
- Document reaction details: If history suggests non-IgE-mediated reaction (headache, GI symptoms, family history only), patient does not require penicillin skin testing 5
- Consider delabeling: If reaction history inconsistent with true allergy, counsel patient on benefits of removing penicillin allergy label and offer single-dose amoxicillin challenge if patient anxious 5
- If true IgE-mediated history: Maintain penicillin allergy documentation; use alternative antibiotics (cephalosporins with caution given cross-reactivity risk) 8
Symptomatic Management:
- Reassurance that most non-cyclical breast pain resolves spontaneously in up to 50% of cases 1
- Well-fitted supportive bra
- NSAIDs for pain control (document penicillin allergy does not contraindicate NSAIDs)
- Smoking cessation counseling if applicable
Follow-up:
- Return visit after ultrasound completion to review results
- If ultrasound negative: Clinical breast examination in 3-6 months to reassess symptoms 4
- If ultrasound demonstrates abnormality: Proceed per imaging recommendations (biopsy, short-interval follow-up, or routine screening)
- Establish regular screening schedule: Clinical breast examination every 3 years until age 40, then annually 3, 4
Patient Education:
- Breast self-awareness: Report any new lumps, skin changes, or nipple discharge promptly 4
- Natural history of non-cyclical mastalgia
- Importance of maintaining updated family history at future visits
- Benefits of penicillin allergy delabeling if appropriate
