I now have comprehensive information from multiple textbooks to compile a thorough answer on the treatment of fibrocystic disease. Let me synthesize it.

Treatment of Fibrocystic Disease (Fibrocystic Breast Changes)

Fibrocystic change represents a spectrum of benign breast conditions - cysts, stromal fibrosis, adenosis, epithelial metaplasia, and apocrine change - driven by an exaggerated breast response to hormonal cycling. The terms "fibrocystic disease," "mammary dysplasia," and ANDI (Aberrations of Normal Development and Involution) are used interchangeably in older and newer literature.

1. Reassurance First

The vast majority of patients require no specific treatment. Most patients need only reassurance that fibrocystic change is a transient phenomenon of aging, associated with hormonal effects on glandular breast tissue, that eventually subsides at menopause. Simple mastectomy or extensive breast tissue removal is not indicated.

Berek & Novak's Gynecology, p. 982
Sabiston Textbook of Surgery, p. 1384

2. Non-Pharmacological Measures

a. Supportive Brassiere

An appropriately sized, well-fitted support bra (including at night) is one of the most effective non-drug interventions. An ill-fitting bra is associated with a threefold risk of mastalgia. In a randomized trial, wearing a sports bra produced greater pain relief than hormonal modulation with danazol.

b. Caffeine Restriction

The role is controversial, but some studies suggest eliminating coffee, tea, and chocolate improves symptoms. Many patients self-report relief after caffeine withdrawal.

c. Diet and Weight

Maintaining a healthy body weight reduces estrogen load. Regular exercise (three times weekly) has been associated with improved quality of life in randomized controlled trials.

d. Cyst Aspiration

For symptomatic simple cysts, aspiration usually resolves the pain. Large cysts that rapidly recur after aspiration can be managed definitively with percutaneous vacuum-assisted excision. Cyst fluid does not need cytologic analysis unless it is bloody or a mass persists.

Sabiston Textbook of Surgery, p. 1384

3. Vitamins and Supplements

These have been investigated but have insufficient evidence to draw clear conclusions:

Supplement	Evidence
Vitamin E	Anecdotal benefit from biochemical changes in fibrocystic tissue; not confirmed in controlled trials
Vitamin B6	Suggested due to biochemical effects on breast tissue; no robust clinical confirmation
Evening primrose oil (γ-linolenic acid, GLA)	Was studied for its effect on prostaglandin synthesis; failed to demonstrate efficacy over placebo in later trials, though safe and without significant side effects
Chamomile extract	Very small RCTs show symptom improvement; likely the safest non-hormonal supplement option, but true efficacy may be negligible

Berek & Novak's Gynecology, p. 984

4. Pharmacological Treatment (for Mastalgia)

Treatment is directed mainly at mastalgia (breast pain), which is the dominant symptom. A pain-score diary for at least 1 month helps classify pain as cyclic vs. non-cyclic and monitor response.

a. Hormonal Agents (First-Line for Moderate-Severe Pain)

Drug	Mechanism	Dose	Notes
Danazol (Danocrine)	Synthetic androgen; suppresses pituitary gonadotropin, prevents LH surge, inhibits ovarian steroid formation	100-200 mg twice daily, then taper to 100 mg/day	Only FDA-approved drug for mastalgia; significant androgenic side effects (acne, edema, voice change, weight gain, hirsutism, depression) - many patients discontinue
Tamoxifen	SERM (selective estrogen receptor modulator)	Low dose (10 mg/day); can be used topically	Effective for cyclic and noncyclic pain; off-label for mastalgia
Toremifene	SERM	-	Recognized treatment for mastalgia
Ormeloxifene	SERM	-	Recognized treatment; widely used in some regions
Bromocriptine	Dopamine agonist; inhibits prolactin (PRL) release	2.5 mg twice daily for 3-6 months	Useful when TRH-induced elevated PRL is present; side effects: nausea, vomiting, headache
Depo-Provera (medroxyprogesterone)	Progestogenic; suppresses ovarian hormones	Injectable	Recognized for mastalgia; also reduces cyclic engorgement
OCP (combined oral contraceptive)	Suppresses cyclical hormonal fluctuation	Standard dosing	Reduces fibrocystic changes and fibroadenomas as a noncontraceptive benefit

Note: GnRH analogs (e.g., Lupron/leuprolide) are not recommended for fibrocystic breast disease. They are effective for mastalgia but have significant side effects (bone loss, hypoestrogenism) and have no established role in fibrocystic disease management specifically.

Berek & Novak's Gynecology, p. 990-991
Sabiston Textbook of Surgery, p. 1384
Bailey & Love's Short Practice of Surgery, 28th Ed., p. 941

b. NSAIDs

For extramammary or noncyclic chest-wall pain (e.g., Tietze syndrome, scapulothoracic bursitis), NSAIDs plus heat are recommended. Trigger point injections with local anesthetic and steroid along the medial scapular border are both diagnostic and therapeutic for referred scapulothoracic pain.

5. Surgical Intervention

Surgery is conservative and reserved for specific indications:

Biopsy is indicated when:

No cyst fluid is obtained on aspiration
Fluid is bloody or thick
The cyst is complex or has an intracystic mass
A mass persists after aspiration
A suspicious mass fails to resolve at short-interval follow-up imaging

The primary surgical objective is to exclude carcinoma, not to treat fibrocystic change itself.

Berek & Novak's Gynecology, p. 982

6. Cancer Risk Context

Treatment decisions must account for histologic subtype:

Nonproliferative fibrocystic change - no increased cancer risk; reassurance is definitive treatment
Proliferative change without atypia - ~2x cancer risk; surveillance
Atypical ductal/lobular hyperplasia - ~5x cancer risk; closer follow-up warranted
Family history + atypia - up to 11x increased risk

Cysts alone do not increase cancer risk. Hormonal therapies (danazol, tamoxifen) may offer secondary cancer risk reduction in high-risk groups.

Summary Algorithm

        |
        v
Exclude malignancy (exam + age-appropriate imaging ± biopsy)
        |
        v
Reassurance + lifestyle (bra support, caffeine restriction, exercise)
        |
        v
Mild-moderate pain → OCP / Vitamin E / supplements (anecdotal)
        |
        v
Moderate-severe cyclic mastalgia → Tamoxifen / Toremifene / Ormeloxifene
        |
        v
Severe, refractory → Danazol (FDA-approved) or Bromocriptine (if elevated PRL)
        |
        v
Symptomatic cysts → Aspiration (± excision if recurrent/complex)
        |
        v
Surgical biopsy only for indications above (never prophylactic mastectomy)
