Lymphedema Risk After Mastectomy: Statistics and Prevention

Incidence of Lymphedema Post-Mastectomy

Approximately 10–25% of women who undergo axillary lymph node dissection (ALND) as part of mastectomy develop lymphedema. Risk is lower with sentinel lymph node biopsy (SLNB) alone (~5–10%).

Risk Factors

• Extent of node removal (ALND vs. SLNB)
• Radiation to the axilla
• Obesity (BMI ≥30)
• Postoperative infection or seroma
• Taxane-based chemotherapy

Prevention & Early Detection

• Baseline arm measurements pre-surgery; regular follow-up measurements.
• Skin care: avoid cuts, burns, insect bites; moisturize daily.
• Gradual return to exercise; avoid heavy lifting initially.
• Compression sleeve for air travel or strenuous activity if high risk.
• Report swelling, heaviness, or tightness promptly—early intervention (compression therapy, manual lymphatic drainage) improves outcomes.
