Breast and Lymphatic System
On this page 8 sections
In 30 seconds
Breast assessment is a combination of inspection (looking) and Palpation Examining by touch, using the finger pads in small circles Full entry → (feeling) of the breast tissue, and it is always paired with assessment of the lymphatic system — the network of vessels and nodes that drains fluid from the breast and nearby regions. The lymphatic system is a key route for immune cells, and it is also the route by which breast cancer cells can spread, which is why the axillary (underarm) lymph nodes are checked during the same examination.
The nurse's role is not to decide whether a finding is cancer. It is to perform the exam competently, describe findings objectively (location, size, shape, consistency, mobility), recognize what is a normal variant versus a change worth reporting, and teach the patient what to watch for and when to seek follow-up. This is an educational topic: actual breast exam policies, who performs them, and screening schedules vary by institution, practice setting, and evolving national guidelines.
Why this matters
Breast cancer is one of the most common cancers affecting women, and people of all genders can develop breast disease. The nurse is often the first clinician to hear "I found a lump." How the nurse responds matters: most breast lumps are benign, but a new, persistent, or changing lump deserves prompt provider evaluation. Describing a finding precisely — clock position, distance from the nipple, the Tail of Spence The portion of breast tissue that extends diagonally up into the armpit Full entry → (breast tissue extending toward the armpit) — makes the difference between a vague chart note and a finding a provider can act on. Lymph node assessment matters because enlarged or fixed nodes provide context for any breast finding and for infection and inflammation generally.

Core Concepts
Inspection of the breasts
Inspection happens first, with the patient seated and disrobed to the waist with privacy and draping:
- Observe size, shape, and symmetry of both breasts. Some asymmetry is a common normal variant.
- Inspect the skin: color, texture, visible veins, dimpling, puckering, or an orange-peel appearance (Peau d'orange Skin that looks dimpled like an orange peel Full entry →) — any skin change is a finding to document and report.
- Inspect the nipples: position, direction, inversion, retraction, and any crusting, ulceration, or discharge. Note whether inversion is new (a change) or lifelong (often a normal variant).
- Repeat inspection with arms overhead and hands pressed on hips — position changes can reveal subtle dimpling or retraction.
Palpation of the breasts
- Palpate with the finger pads of the first three fingers, using a light, then medium, then deeper pressure, in small circular motions.
- Use a systematic pattern so no tissue is skipped: the Clock-face method A palpation pattern that treats the breast like a clock face Full entry → (imaginary clock around the nipple, covering each hour, then the nipple itself) or the vertical strip method (top to bottom in straight lines).
- Cover all four quadrants plus the tail of Spence, which extends diagonally into the axilla — a common site for breast tissue and for missed lumps.
- For patients with large breasts, use a Bimanual technique Supporting the breast with one hand while palpating with the other Full entry → (one hand supporting the breast from below while the other palpates) so deeper tissue is reached.
- When you find a lump, describe: location (clock position and distance from the nipple), size, shape, consistency (soft, firm, hard, rubbery), mobility (moves freely vs. fixed), and tenderness. Note any nipple discharge and its color and character (do not attempt to express discharge; describe what is present).
- Also check the axillae for breast tissue, lymph nodes, and tenderness.
Lymph node assessment
Lymph nodes are assessed by light palpation with the finger pads, using a gentle circular motion:
- Cervical nodes (anterior and posterior chains, plus supraclavicular) — assessed with the patient seated, head slightly tilted.
- Axillary nodes — central, lateral, subscapular (posterior), and pectoral (anterior) groups. Support the patient's arm so the muscles are relaxed, then reach into the axilla.
- Epitrochlear nodes — in the groove between the biceps and triceps just above the elbow.
- Inguinal nodes — in the groin.
Normal nodes are often not palpable; when palpable they are usually small, soft, mobile, and nontender. Document any node that is enlarged, hard, fixed, matted, or tender, and note whether enlargement is localized (one region, suggesting a local problem) or generalized (several regions, suggesting a systemic process).
Health teaching and follow-up
The nurse teaches breast self-awareness: knowing what is normal for one's own body and reporting changes such as a new lump, skin or nipple changes, or persistent discharge. Self-awareness is not a substitute for screening — screening recommendations vary by age, risk, and current national guidelines, so treat specific schedules as institutional/provider guidance rather than memorized facts. When a patient reports a new finding, the nurse documents it and facilitates prompt referral. Findings are never dismissed with "it's probably nothing" — reassurance is the provider's to give after evaluation.
Clinical Scenario: "I Found a Lump in the Shower"
Ms. Chen, age 45, tells the nurse during an admission assessment that she found "a pea-sized bump" near her armpit two weeks ago. She has not mentioned it to anyone else. The nurse asks gentle questions — when she noticed it, whether it has changed, whether she has any skin changes or discharge — then performs inspection and palpation with her permission. She finds a small, smooth, mobile, nontender lump in the upper outer quadrant of the right breast at the 2 o'clock position, about 3 cm from the nipple, and the axillary nodes feel normal.
The nurse documents precisely: "Palpable 1 cm smooth, mobile, nontender mass, right breast, 2 o'clock, 3 cm from nipple; axillary nodes nonpalpable." She tells Ms. Chen honestly that most lumps are benign but that any new lump needs evaluation, and she arranges for the finding to be brought to the provider's attention. She does not say "don't worry, it's nothing" — because she cannot know that. This is assessment, education, and referral — exactly the nurse's scope.
Common Confusions
| Do Not Confuse | With | Difference |
|---|---|---|
| A new lump | Normal glandular tissue | Normal tissue feels consistent with the rest of the breast; a new, distinct lump that persists is a finding to evaluate |
| Tail of Spence tissue | An axillary lymph node | Breast tissue in the axillary tail is soft and sheet-like; a node is a discrete small round structure |
| Lifelong nipple inversion | New nipple retraction | Lifelong inversion is usually a normal variant; new retraction is a change to report |
| Breast self-examination | Breast self-awareness | BSE is a scheduled exam technique (taught in some settings); self-awareness is knowing your own normal and reporting changes — they are not the same and neither replaces screening |
| "It feels benign" | "It is benign" | A nurse can describe consistency but cannot rule out disease — only evaluation can |
| Mastitis | Cancer | Both can cause redness, warmth, and tenderness; the nurse documents and refers rather than choosing between them |
Eli explains
The same idea, in plain words
Explain it like I’m 10
Your breasts are made of soft tissue, and under each armpit and along your neck and groin you have small "filters" called lymph nodes that help your body fight germs. The nurse looks at both sides to check they look similar, then gently presses all around in a pattern — like mowing a lawn in straight lines so no patch is missed — to feel for any new bumps. If something feels different, the nurse writes down exactly where and what it feels like, tells you to have it checked, and doesn't guess what it is.
Key takeaways
- Inspect before you palpate, with the patient seated; use multiple arm positions to expose dimpling.
- Palpate in a pattern (clock-face or vertical strip) and include the tail of Spence — lumps are missed here most often.
- Describe, don't diagnose: location (clock position + distance from nipple), size, shape, consistency, mobility, tenderness.
- Palpate lymph nodes gently with finger pads; note size, mobility, consistency, and tenderness, and whether enlargement is localized or generalized.
- Peau d'orange, new retraction, or bloody nipple discharge are changes that warrant prompt provider evaluation.
- Most breast lumps are benign, but only evaluation can tell — never give false reassurance.
- Scope note: who performs breast exams and how they are taught (self-exam vs. self-awareness) varies by institution and evolving guidelines.

6 review questions from the chapter. Try each one, then open the answer.
Why is the tail of Spence included in breast palpation?
Show answer
Because breast tissue extends into the axilla there, and it is a common site for lumps — skipping it means missing tissue.
What four characteristics should you document when you palpate a lump?
Show answer
Location (clock position and distance from nipple), size, shape, consistency, mobility, and tenderness.
What is the difference between a localized and a generalized finding of enlarged lymph nodes?
Show answer
Localized enlargement (one region) points toward a local process (e.g., infection in the drained area); generalized enlargement (several regions) points toward a systemic process — but causes and next steps are the provider's to determine.
A patient has skin that looks like an orange peel over one breast. What is this called, and what should the nurse do?
Show answer
Peau d'orange — document it and report it promptly for provider evaluation.
What is the difference between breast self-examination and breast self-awareness?
Show answer
Self-awareness is knowing one's own normal and reporting changes; self-examination is a scheduled palpation technique. Neither replaces screening, and teaching practices vary by institution and guidelines.
Which lymph node groups are assessed during a lymphatic system examination?
Show answer
Cervical (including supraclavicular), axillary, epitrochlear, and inguinal groups.
