Management of Bilateral Breast Pain
For bilateral breast pain, reassurance alone without imaging is the primary management approach, as the risk of malignancy is extremely low (0-3%) and imaging rarely changes management, with 86% of women with mild pain and 52% with severe pain experiencing symptom resolution through reassurance alone. 1
Initial Clinical Assessment
The key distinction is whether the pain is focal versus diffuse, as this determines the need for imaging 1:
- Diffuse bilateral breast pain: No imaging is indicated regardless of whether pain is cyclical or noncyclical, with all imaging modalities rated as "usually not appropriate" (ACR rating 1-2 out of 9) 1, 2
- Focal bilateral pain: This is atypical and warrants closer evaluation, as noncyclical pain tends to be unilateral and focal 1
Determine if the pain is cyclical or noncyclical 3:
- Cyclical mastalgia (70% of cases): Diffuse, bilateral or unilateral pain that waxes and wanes with the menstrual cycle, most pronounced in the luteal phase, typically affecting women in their third decade 3, 4
- Noncyclical mastalgia (25% of cases): Usually unilateral, focal, often subareolar or inner breast location, not related to menstrual cycle 3, 1
Management Algorithm
For Diffuse Bilateral Pain with Normal Clinical Exam
First-line approach (no imaging needed) 1, 4:
- Reassurance that breast pain alone rarely indicates cancer—this is therapeutic, not just informational 1, 4
- Well-fitted supportive bra, especially during exercise and for women with large breasts 1, 4
- Over-the-counter NSAIDs (ibuprofen or naproxen) as needed for pain control 1, 2
- Ice packs or heating pads applied for comfort 1, 4
- Regular physical exercise to help alleviate symptoms 4
For Focal Bilateral Pain
If the clinical exam is normal but pain is focal 1:
- Age ≥30 years: Diagnostic mammogram with ultrasound 1
- Age <30 years: Ultrasound only (ACR rating 5/9, discretionary) 1
Natural History and Expectations
- Spontaneous resolution occurs in 14-20% of cyclical mastalgia cases within 3 months 4
- Recurrence is common, with at least 60% of cases recurring within 2 years 3
- Menopause brings resolution in approximately 40% of women with cyclical pain 3
- Women starting cyclical pain before age 20 typically have a prolonged course 3
Critical Pitfalls to Avoid
Do NOT order imaging for diffuse bilateral breast pain 1, 4:
- Mammography in women under 40 exposes patients to unnecessary radiation without benefit (ACR rating 1/9) 1
- MRI has no role in breast pain evaluation and leads to unnecessary biopsies of benign findings without improving cancer detection 1, 2
Do NOT recommend caffeine elimination 4:
- Despite widespread belief, there is no convincing scientific evidence that reducing caffeine intake affects breast pain 3, 4
Do NOT dismiss pain without proper evaluation 4:
- While rare, some cancers (especially invasive lobular and anaplastic carcinomas) can present with pain 2
Do NOT aspirate small cysts found incidentally on ultrasound 1:
- These are unlikely to be the source of diffuse pain and aspiration provides no benefit 1
When to Consider Extramammary Causes
If breast exam and any indicated imaging are normal, consider 2, 4:
- Costochondritis (chest wall inflammation)
- Muscle strains from exercise or poor posture
- Nerve entrapment syndromes
- Referred pain from cardiac, pulmonary, or gastrointestinal sources
Special Considerations
- Smokers with burning periareolar pain: Advise smoking cessation, as 25% of noncyclical pain is associated with duct ectasia and periductal inflammation related to heavy smoking 3, 2
- Medication review: Hormonal medications (hormone replacement therapy, oral contraceptives, infertility treatments) and SSRIs can cause breast pain 3
- Large breasts: Noncyclical pain may simply relate to breast size and associated neck, shoulder, and back pain—emphasize proper bra fitting 3, 2
