CHAPTER: MANAGEMENT OF BENIGN BREAST DISEASES
GENERAL PRINCIPLES OF MANAGEMENT
The cornerstone of managing any breast complaint is the Triple Assessment, which must be completed before any therapeutic decision:
- Clinical assessment - History and physical examination
- Radiological assessment - Mammography (>35 years) and/or ultrasonography (<35 years)
- Pathological assessment - Fine needle aspiration cytology (FNAC) or core needle biopsy (CNB)
All three arms of the triple assessment must be concordant (i.e., all benign or all malignant) before a diagnosis can be made. A discordant result mandates surgical excision.
ANDI CLASSIFICATION AND MANAGEMENT OVERVIEW
The ANDI (Aberrations of Normal Development and Involution) classification by Hughes, Mansel, and Webster provides the conceptual framework:
| Phase | Normal Process | Aberration | Disease |
|---|
| Reproductive | Lobule development | Fibroadenoma | Giant fibroadenoma |
| Reproductive | Stroma development | Cyclical mastalgia | Incapacitating mastalgia |
| Reproductive | Epithelial proliferation | Epitheliosis/adenosis | Atypical hyperplasia |
| Involutional | Lobular involution | Macrocysts, sclerosing adenosis | Epithelial hyperplasia with atypia |
| Involutional | Ductal involution | Duct ectasia | Periductal mastitis/abscess |
| Involutional | Epithelial turnover | Mild hyperplasia | Atypical hyperplasia |
1. MASTALGIA (BREAST PAIN)
Classification
- Cyclical mastalgia - Pain linked to menstrual cycle; begins ~day 14, worsens until menstruation; bilateral; most common (65-70% of cases)
- Non-cyclical mastalgia - Not linked to cycle; may be localized ("trigger spot"); associated with duct ectasia, periductal mastitis, musculoskeletal causes (Tietze's syndrome)
- Extra-mammary pain - Musculoskeletal, costochondritis, angina, biliary colic (referred)
Management
Step 1: Reassurance
- After negative triple assessment, reassurance alone resolves symptoms in up to 85% of women with mild-to-moderate cyclical mastalgia
- Record a breast pain chart for 1 month to document the pattern
Step 2: Conservative (first-line)
- Well-fitting supportive brassiere (worn day and night)
- Evening primrose oil (gamma-linolenic acid) 3g/day - mild benefit, well tolerated
- Reduce caffeine intake; low-fat diet
- NSAIDs (topical diclofenac applied to the breast)
Step 3: Medical (second-line - for incapacitating mastalgia)
| Drug | Dose | Notes |
|---|
| Tamoxifen | 10-20 mg/day × 3-6 months | Most effective; 70-80% response; SE: hot flashes, menstrual irregularities |
| Danazol | 200-400 mg/day | Effective but androgenic side effects (acne, hirsutism, voice change); rarely used now |
| Bromocriptine | 2.5-5 mg/day | Dopamine agonist; side effects limit use |
| Ormeloxifene (Centchroman) | 60 mg twice weekly | SERM; used in South Asia; fewer SE than tamoxifen |
| GnRH analogues | Monthly SC injection | Reserved for severe refractory cases; menopausal SE |
Non-cyclical mastalgia: Identify and treat trigger spot with local infiltration of methylprednisolone + bupivacaine. NSAID gel. Treat underlying cause.
Surgical treatment: No role in mastalgia. Surgery does not reliably cure breast pain.
2. FIBROADENOMA
Management Principles
Fibroadenoma is classified as an aberration of normal lobular development. The majority do not require surgical excision and can be managed conservatively with serial imaging.
Conservative Management (Observation)
Indications for observation:
- Age <30 years with typical features on USS and FNAC/CNB
- Size <3-4 cm
- No rapid growth
- No atypia on biopsy
- Patient reassured and concordant
- Core biopsy-proven concordant fibroadenoma without atypia (ASBrS/SBI 2025 Guidelines)
Patients with biopsy-proven concordant fibroadenomas do not require routine imaging follow-up and may return to age-appropriate screening.
Medical Management
- Tamoxifen / Ormeloxifene - Regression observed in some cases; used in young women wishing to avoid surgery
- Anti-oestrogenic treatment can lead to involution in up to 30% of small fibroadenomas
Indications for Surgical Excision
- Age >30 years
- Size >3-5 cm
- Rapid growth (>20% increase in 6 months)
- Atypia or suspicious features on core biopsy
- Suspicious features on imaging (microlobulation, posterior shadowing)
- Family history of breast cancer
- Patient's preference / significant anxiety
- Indeterminate "cellular fibroepithelial lesion" on core biopsy (cannot exclude phyllodes)
- Fibroadenoma in elderly patients (include rim of normal tissue due to risk of occult malignancy)
Operative Note: Excision of Fibroadenoma
Pre-operative:
- Confirm diagnosis with triple assessment
- Mark the lump in the standing/sitting position pre-operatively
- Consent: scar, bleeding, infection, recurrence, sensory changes, need for re-excision
Anaesthesia: General anaesthesia (or local for small, superficial lesions)
Position: Supine with arm abducted; a small pad under ipsilateral shoulder
Incision:
- Periareolar (Langer's lines) incision for central/periareolar lesions - best cosmesis
- Radial incision - acceptable for peripheral lesions in younger women
- Submammary incision - for giant fibroadenoma or lesions near inframammary fold
Steps:
- Skin incision along planned line, carried through dermis
- Dissect skin flaps using cutting diathermy or scissors to reach the lump
- The fibroadenoma is identified by its white, glistening capsule
- Enucleation: Hold the mass with Allis forceps or finger dissection; blunt dissection along capsular plane separating it from surrounding breast parenchyma - the mass "shells out" cleanly
- Complete excision without transection of the mass (ASBrS 2025 - transection increases recurrence risk and impairs histopathological assessment)
- In patients >30 years or elderly: excise with a 2-3 mm rim of normal surrounding tissue
- Achieve haemostasis with bipolar diathermy
- Specimen sent for histopathology (mandatory)
- Wound closure: Absorbable sutures to approximate breast parenchyma (2/0 Vicryl); subcutaneous 3/0 Vicryl; subcuticular 4/0 Monocryl or Prolene for skin
Post-operative care:
- Supportive brassiere worn for 2-3 weeks
- Wound review at 1-2 weeks
- Histopathology review at 2-3 weeks
- Return to age-appropriate breast screening
3. PHYLLODES TUMOUR
Classification (Histological)
| Grade | Mitotic Rate | Margins | Behaviour |
|---|
| Benign | <4/10 HPF | Pushing | Low recurrence |
| Borderline | 4-9/10 HPF | Mixed | Intermediate |
| Malignant | >10/10 HPF | Infiltrating | May metastasize (haematogenous) |
Management
- All phyllodes tumours require surgical excision - cannot be observed
- Core biopsy reported as "cellular fibroepithelial lesion" should be excised (cannot distinguish from fibroadenoma histologically)
Operative Note: Wide Local Excision of Phyllodes Tumour
Aim: Complete excision with a 1-2 cm clear margin (Bailey & Love recommends 2 cm margin along with overlying skin and underlying pectoralis fascia due to high local recurrence rate)
Steps:
- Mark 2 cm clearance around the tumour pre-operatively with a skin marker
- Elliptical skin incision including overlying skin (if tumour is large or skin is thinned)
- Dissection through breast parenchyma maintaining the 2 cm margin
- Include underlying pectoralis fascia in the excision specimen
- Reconstruct breast tissue with mobilization of adjacent parenchymal flaps (oncoplastic technique for large defects)
- Closure as per fibroadenoma excision
Re-excision: Not routinely required for benign phyllodes with positive margin if the mass was completely excised without transection (ASBrS/SBI 2025). Consider re-excision if mass was transected or there is concern for residual disease.
Follow-up: No routine imaging follow-up required for benign phyllodes; return to age-appropriate screening. Clinical surveillance for borderline/malignant types.
4. BREAST CYSTS
Management
Simple cysts (on USS: anechoic, well-circumscribed, posterior enhancement):
- Asymptomatic simple cysts: No intervention required (Choosing Wisely - ASBrS)
- Symptomatic or anxious patient: Ultrasound-guided or palpation-guided aspiration
- If cyst disappears completely on aspiration and fluid is non-bloody: Discard fluid (cytology not required)
- If bloody aspirate: Send for cytology; arrange USS to confirm complete resolution
- If cyst recurs after >2 aspirations: Consider excision
Complex cysts (thick septae, internal debris, solid component):
- Core needle biopsy with clip marking
- Indeterminate/suspicious component: Surgical excision
Operative Note: Breast Cyst Aspiration
Technique (Ultrasound-guided):
- Patient supine, ipsilateral arm raised
- Confirm cyst on USS and plan approach
- Skin prep, sterile field
- Local anaesthesia (1% lidocaine) to skin and subcutaneous tissue
- 21G needle attached to 10 mL syringe introduced under real-time USS guidance into the cyst
- Aspirate until cyst collapses completely; confirm on USS
- Note fluid character (straw-coloured, green, brown = benign; bloody = suspicious)
- Apply pressure dressing; reassess on USS
5. PERIDUCTAL MASTITIS AND BREAST ABSCESS
Periductal Mastitis
Pathogenesis: Chronic non-lactational periductal inflammation (autoimmune? squamous metaplasia of lactiferous ducts in smokers) → ductal obstruction → secondary infection → subareolar abscess → mammary duct fistula
Organisms: Staphylococci, enterococci, anaerobic streptococci, Bacteroides
Conservative Management
- Antibiotics: Co-amoxiclav (625 mg TID × 2-3 weeks) OR Flucloxacillin + Metronidazole (covers anaerobes) OR Ciprofloxacin + Metronidazole
- Duration: 2-3 weeks
- Needle aspiration of fluctuant abscess under USS guidance
- Smoking cessation (strong association with periductal mastitis)
- Rule out TB (GeneXpert MTB/RIF on pus)
Lactational Mastitis Management
- Continue breastfeeding / regular emptying (prevents milk stasis)
- Antibiotics: Flucloxacillin 500 mg QID or Co-amoxiclav × 10-14 days (covers S. aureus)
- Analgesics, warm compresses
- If abscess forms: USS-guided aspiration (first line); repeat if needed
- Incision and drainage reserved for: failure of aspiration, multiloculated collections, deep-seated abscess, skin necrosis
Operative Note: Incision and Drainage of Breast Abscess
Anaesthesia: General anaesthesia (local inadequate in inflamed tissue)
Position: Supine
Incision:
- Non-lactational/subareolar abscess: Circumareolar incision at the areolar margin
- Peripheral abscess: Radial incision at point of maximum fluctuation (avoids major ducts)
- Avoid a dependent incision in the inframammary fold (poor drainage)
Steps:
- Incision through skin over the abscess
- Blunt dissection with artery forceps through cavity (break loculations)
- Drain all pus; send pus for culture and sensitivity, AFB, GeneXpert
- Thorough washout with warm saline (0.9%)
- Do NOT primarily close - pack cavity loosely with ribbon gauze soaked in povidone-iodine or leave drain
- Wound left open to drain and heal by secondary intention
- Daily dressings; wound re-examined in 48 hours
For subareolar abscess with mammary duct fistula:
- In fit patients: Hadfield's operation (total duct excision / Patey's major duct excision) after the acute episode settles
- Fistula excision: Probe the fistulous tract and excise the entire tract with the ductal cone
6. DUCT ECTASIA
Management
| Stage | Management |
|---|
| Asymptomatic (USS finding) | Reassurance, no intervention |
| Nipple discharge (no infection) | Reassurance; major duct excision if profuse/persistent |
| Periductal inflammation | Antibiotics (co-amoxiclav + metronidazole × 2-3 weeks) |
| Subareolar abscess | Aspiration/I&D then elective major duct excision |
| Mammary duct fistula | Hadfield's major duct excision (elective) |
| Nipple retraction | Cosmetic: subareolar duct release |
Operative Note: Hadfield's Major Duct Excision (Total Duct Excision)
Indication: Profuse nipple discharge, recurrent subareolar abscess, mammary duct fistula associated with duct ectasia/periductal mastitis
Pre-operative: Consent patient regarding potential difficulty with breastfeeding; nipple numbness; possible change in nipple projection
Steps:
- Circumareolar incision (around lower half of areola)
- Raise skin flap to expose the base of the nipple
- Insert fine lacrimal probe into the discharging duct to guide excision
- Transfix the ductal complex at the base of the nipple with a stay suture
- Excise a 2-3 cm length of the entire ductal cone (all major ducts) flush with the undersurface of the nipple
- Specimen sent for histopathology
- Haemostasis; pack residual cavity or close with absorbable sutures
- Skin closed with interrupted 4/0 Prolene
7. NIPPLE DISCHARGE (SURGICAL APPROACH)
Indications for Surgical Duct Excision
- Persistent unilateral spontaneous nipple discharge
- Bloody or blood-stained discharge
- Discharge from a single duct
- Failure to identify causative lesion on imaging
- Intraductal papilloma confirmed on ductography/MRI/USS
Operative Note: Single Duct Excision (Microdochectomy)
Steps:
- Express discharge at the start of operation to confirm the duct and mark with a suture
- Insert lacrimal duct probe into the culprit duct
- Circumareolar incision; raise subareolar flap
- Excise the probed duct along with the surrounding cone of tissue (2-3 cm length)
- Send specimen in toto for histopathology
- Close as per major duct excision
If a single duct cannot be identified, proceed to total duct excision (Hadfield's).
8. GRANULOMATOUS MASTITIS
Management
- Obtain core needle biopsy to confirm diagnosis and exclude carcinoma
- Exclude TB (histology, AFB staining, GeneXpert, cultures)
- Idiopathic granulomatous mastitis (IGM):
- Mild: Observation (spontaneous resolution in some cases)
- Moderate-severe: Corticosteroids (prednisolone 0.5-1 mg/kg/day, taper over 6-8 weeks)
- Abscess: Drain if fluctuant
- Refractory: Methotrexate or surgical excision
- Recurrence rate is high (~25-50%) regardless of treatment modality
9. FAT NECROSIS
Management
- Reassure patient (often presents as hard, irregular mass mimicking carcinoma)
- Triple assessment mandatory to exclude malignancy
- No treatment required once benign nature confirmed
- Surgical excision if diagnostic uncertainty persists or for cosmesis

RECENT EVIDENCE (2025)
The
American Society of Breast Surgeons and Society of Breast Imaging 2025 Guidelines (Rosenberger et al., JAMA Surgery, 2025 - PMID 41123921) provide the most current consensus on fibroepithelial lesions:
- Biopsy-proven concordant fibroadenoma without atypia does not require excision unless symptomatic, large, or rapidly growing
- Complete excision without transection is recommended when surgery is performed
- Re-excision of benign phyllodes with positive margin is not routinely required
- Patients can return to age-appropriate screening without additional follow-up imaging
A 2025 systematic review (Ramgopal et al., Clinical Imaging, PMID 41061430) confirms cryoablation as an emerging non-surgical option for biopsy-proven benign fibroadenomas - suitable for patients wishing to avoid open surgery.
