II. Pathophysiology

  1. Breast Pain thought to be related to Estrogen excess

III. Causes

  1. See Medication Causes of Mastalgia
  2. Cyclic Breast Pain
    1. Pain related to Menses (typically during Luteal Phase, second half of cycle)
  3. Non-cyclic Breast Pain
    1. Costochondritis
    2. Chest Trauma
    3. Sclerosing adenosis
    4. Large pendulous Breasts
    5. Breast Cancer (represents under 5% of Breast Pain)
      1. Associated with focal Breast Pain (contrast with diffuse Breast Pain in benign Mastalgia)

IV. History

  1. Location: Focal or Diffuse
    1. Focal Breast Pain more concerning for malignancy than diffuse pain
  2. Duration of Breast Pain
  3. Unilateral or Bilateral
  4. Changes with Menstrual Cycle
  5. Relationship to hormonal replacement therapy
  6. Rank Breast Pain on a 10 point scale
  7. Altered life style
  8. Excessive Worry or emotional stress

VI. Evaluation

  1. Breast Mass present
    1. Evaluate as Breast Mass
  2. Diffuse Breast Pain, no Breast Mass present, and no significant Breast Cancer Risk Factors
    1. Very reassuring as low risk for malignancy
    2. Routine Mammography starting at age 40 years (or age 30 years if Breast Cancer Risk Factors)
  3. Focal Breast Pain and no Breast Mass present
    1. Younger than age 30 years
      1. Consider targeted breast Ultrasound
      2. Consider repeat Breast Exam in 1-2 months
    2. Older than age 30 years
      1. Step 1: Breast Imaging
        1. Diagnostic Mammogram AND
        2. Targeted breast Ultrasound
      2. Step 2a: Negative Breast imaging
        1. Breast Cancer Risk Factors
          1. Consider subspecialist referral
          2. Routine Mammography starting at age 30 years
        2. No Breast Cancer Risk Factors
          1. Very reassuring as low risk for malignancy
          2. Routine Mammography starting at age 40 years
      3. Step 2b: Abnormal Breast imaging
        1. Breast FNA or Breast core biopsy

VII. Associated Conditions

VIII. Management: Measures with best efficacy

  1. Expect spontaneous resolution in up to 80-90% of patients
  2. General measures
    1. Wear supportive Brassiere or Sports Bra
    2. Eliminate Caffeine
  3. First-line preparations
    1. NSAIDs
    2. Topical diclofenac (Solaraze)
  4. Refractory preparations
    1. Tamoxifen
    2. Danazol

IX. Management: Other measures with less supporting evidence

  1. Vitamin E Supplementation up to 800 IU qd
  2. Herbal therapies with variable efficacy
    1. Evening Primrose Oil 1500-3000 mg orally daily
    2. Chaste Tree Berry 30 to 40 mg orally daily (PMS)
