    2. Cyclic Breast Pain (responsible for two thirds of all Breast Pain, esp. age 20-40 years old)

      1. Focal Breast Pain more concerning for malignancy than diffuse pain

    2. Non-cyclical Breast Pain causes (as above)
    3. Referred pain (cardiopulmonary, gastrointestinal)
  8. Evaluation
    1. Breast Mass present
      1. Evaluate as Breast Mass (imaging, possible biopsy, consider Breast surgeon referral)
      2. Simple Breast cyst may undergo Breast Cyst Aspiration
    2. Diffuse Breast Pain, no Breast Mass present, and no significant Breast Cancer Risk Factors
      1. Diagnostic Mammography starting at age 40 years (or age 30 years if Breast Cancer Risk Factors)
      2. Low risk for malignancy
        1. Risk of malignancy 0.5% after negative Mammography and Clinical Breast Exam
        2. Holbrook (2018) J Am Coll Radiol 15(115): S276-82 [PubMed]
    3. Focal Breast Pain and no Breast Mass present
      1. Precautions
        1. Consider referred pain sources from the chest and Abdomen
      2. Younger than age 30 years
        1. Consider targeted breast Ultrasound
        2. Consider repeat Breast Exam in 1-2 months
      3. 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
  9. Associated Conditions
    1. Premenstrual Dysphoric Disorder (PMDD or PMS)
  10. 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. Arrange formal bra fitting
        1. Poorly fitting bra identified in up to 70% of women
        2. Properly fitting bra should reduce tension on the Cooper ligaments (esp. in large Breasted women)
        3. Reduced Breast Pain in up to 85% of women who adjust the bra fit
      3. Manage stress, anxiety and depressed mood
    3. First-line preparations
      1. NSAIDs
      2. Topical diclofenac (Solaraze)
    4. Moderate persistent symptoms
      1. Tamoxifen (first-line)
        1. Dose: 10 mg daily for 3 months (may extend for an additional 3 months if effective)
        2. Highly effective (in up to 90% of patients), but symptoms return after discontinuation
        3. Anti-Estrogenic effects (Hot Flashes) and itfvctygvgc ncreased Venous Thromboembolism Risk
      2. Danazol
        1. Anterior pituitary suppressant that is FDA approved for Mastalgia
        2. Dose: Start at 200 mg daily and reduce to 100 mg daily after pain decreases
        3. Less effective than Tamoxifen and with increased androgenic effects, Menorrhagia, myalgias
    5. Severe, refractory symptoms
      1. Goserelin (Zoladex)
        1. Marked, but reversible ovarian suppression to post-menopausal levels
        2. Menopause symptoms
        3. May be used for up to 6 months
  11. Management: Other measures with less supporting evidence
    1. Eliminate Caffeine
    2. Vitamin E Supplementation up to 800 IU qd
    3. 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)
