HA | Primer Breast and Lymphatic System
𩺠Breast Health & Cancer â High-Yield Study Guide (RN prep) 1) Classifications & Key Types DCIS: In-duct only, noninvasive. IDC: Most common (â80â90%), past duct; firm Âą fixed. ILC: â10%; often thickening vs discrete lump. IBC: Aggressive red-swollen breast, peau dâorange; urgent eval. Paget dz (nipple): Erythema, flaking, burning, discharge, pain (late); often linked to intraductal CA. Triple-Negative (ER-/PR-/HER2-): 10â20%; more in younger & Black pts; faster course. 2) Common Benign Fibrocystic changes: Cyclic tender ârubbery/granularâ lumps â pre-menses, â after; hormonal. 3) Red Flags â Refer â ď¸ New mass thatâs hard, fixed, poorly defined. Spontaneous, unilateral, bloody/guaiac+ discharge. Skin changes: peau dâorange, new dimpling/retraction. New nipple inversion. Inflammatory signs (redness/warmth/rapid enlargement) â think IBC. 4) Bedside Approach (Nursing) HPI: COLDSPA for pain/lumps. Teach risk reduction: regular exercise, â¤1 drink/day, weight control; high-risk pts discuss enhanced screening. Med review (can cause pain/discharge): hormones/OCPs, antipsychotics (e.g., haloperidol/risperidone), antidepressants, sedatives, some antihypertensives; herbs: fennel/anise/fenugreek. 5) Screening (ACS-style talking points) đŻ Mammogram: annually from 40 (50â74 may go q2y). CBE: q2â3y in 20sâ30s; yearly âĽ40. BSE: optionalâteach correct method; goal = body awareness. 6) Risk Factors (know these!) đ§Ź Non-modifiable: female, âage, BRCA1/2 (â5â10%), prior LCIS/atypia, early menarche/late menopause, prior chest radiation, dense breasts. Reproductive: nulliparity or 1st birth >30. Lifestyle: obesity, post-meno HRT, alcohol (esp. âĽ2/day), night-shift/2nd-hand smoke, high-fat diet. 7) Physical Exam (how to) đ§Ş Position: Inspect sitting (both breasts exposed); palpate supine. Inspect: symmetry, color/texture, venous pattern, areola/nipple, retraction/dimpling. Palpate: all 4 quadrants + Tail of Spence (đşmost tumors here); note location, size, shape, mobility, consistency, tenderness. Nodes: Axillary anterior (pectoral), posterior (subscap), lateral (brachial), central.
