Breast Cancer Surgery & Lymphedema Reference
From the operative choices to the single most-tested nursing concern after breast surgery: protecting the affected arm. Removing axillary nodes disrupts lymph drainage and creates a lifelong lymphedema risk.

Surgical Options
| Procedure | What it is | Nursing notes |
|---|---|---|
| Lumpectomy (breast-conserving) | Removes the tumor + margin, keeps the breast | Usually followed by radiation; cosmetically conserving |
| Mastectomy | Removes the whole breast (± skin/nipple-sparing variants) | Reconstruction may be immediate or delayed; body-image support |
| Sentinel lymph node biopsy (SLNB) | Removes the first 1–3 draining nodes to check for spread | Lower lymphedema risk; negative SLNB usually avoids full dissection |
| Axillary lymph node dissection (ALND) | Removes a larger group of axillary nodes | Higher lymphedema risk → strict affected-arm precautions |
Affected-Arm Precautions (Lymphedema Prevention)
On the operative side, avoid blood pressure measurement, venipuncture, IV insertion, and injections. Also avoid constrictive clothing/jewelry, carrying heavy bags, and burns/cuts (wear gloves, use sunscreen, treat any break in skin promptly to prevent infection). Elevate the arm after surgery, and begin gentle range-of-motion/arm exercises (e.g., wall-climbing) as ordered to restore mobility.
Recognizing & Managing Lymphedema
Lymphedema is swelling, heaviness, tightness, or aching of the affected arm/hand, which may appear months to years later. Management: elevation, compression sleeves, manual lymphatic drainage, exercise, and meticulous skin care. Teach patients to report new swelling or any sign of infection (redness, warmth, fever) early — cellulitis in a lymphedematous limb is a real risk.
NCLEX Pearls
- ✦Affected arm after axillary surgery: NO BP, venipuncture, IVs, or injections — lifelong.
- ✦ALND has a higher lymphedema risk than SLNB; SLNB samples the first draining node(s).
- ✦Elevate the affected arm post-op and begin gentle ROM/arm exercises as ordered.
- ✦Lymphedema = swelling/heaviness of the arm; manage with elevation, compression, lymphatic drainage, and skin care.
- ✦Protect the arm from cuts, burns, and constriction; treat any skin break promptly to prevent cellulitis.
- ✦Care for surgical drains (empty, record output) and watch for hematoma/infection.
