Lung Cancer Nursing Care
The leading cause of cancer death. It is usually diagnosed late because early disease is silent — so nursing care blends airway and dyspnea management, watching for paraneoplastic and SVC complications, and prevention through smoking cessation and high-risk screening.

Overview
Lung cancer splits into two groups that behave very differently. Non-small cell lung cancer (NSCLC) — adenocarcinoma, squamous cell, large cell — is ~85% of cases, grows more slowly, and is staged by TNM with surgery possible when localized. Small cell lung cancer (SCLC) is aggressive, central, almost always smoking-related, spreads early (usually metastatic at diagnosis), and is treated primarily with chemotherapy and radiation, not surgery. SCLC is the classic cause of paraneoplastic syndromes (see the SCLC vs NSCLC chart).
Key Concepts
Risk & presentation
Smoking causes the great majority; also radon, asbestos, air pollution, and secondhand smoke. Early disease is silent. Later signs: a new or changed chronic cough, hemoptysis, dyspnea, chest pain, hoarseness, recurrent pneumonia, weight loss, and clubbing.
Paraneoplastic syndromes
Tumors (especially SCLC) secrete hormones: SIADH (hyponatremia), ectopic ACTH → Cushing’s, and squamous cell can cause hypercalcemia (PTHrP). These can be the first clue and need their own monitoring/management.
Superior vena cava syndrome
A mediastinal tumor compressing the SVC causes facial/neck/arm edema, distended neck veins, and dyspnea — an oncologic emergency. Elevate the head of bed and notify the provider.
Screening & treatment
Low-dose CT (LDCT) screening is recommended for high-risk older adults with a significant smoking history. Treatment depends on type/stage: surgery (lobectomy/pneumonectomy) for resectable NSCLC, plus chemo, radiation, immunotherapy, and targeted therapy (e.g., EGFR/ALK); SCLC = chemo + radiation.
Assessment Findings
Assess respiratory status closely — cough, hemoptysis, dyspnea, breath sounds, SpO₂, and work of breathing. Note hoarseness, chest/shoulder pain, weight loss, and clubbing. Screen for paraneoplastic clues: hyponatremia (SIADH), hypercalcemia, Cushingoid features. Watch for SVC syndrome (facial/upper-body edema, JVD). After thoracic surgery, monitor chest tubes, airway, and pain.
Nursing Priorities
Optimize breathing
Position upright/high-Fowler’s, give oxygen as ordered, pace activities, and use energy conservation. Manage cough and secretions; treat dyspnea (which may include low-dose opioids per orders in advanced disease).
Catch complications early
Recognize SVC syndrome and report immediately; monitor sodium and calcium for paraneoplastic syndromes; watch for hemoptysis and post-op chest-tube issues.
Support treatment & symptoms
Provide chemo/radiation side-effect care and neutropenic precautions, radiation skin care, nutrition support, and pain/symptom control. Coordinate palliative care early for symptom burden.
Smoking cessation & prevention
Offer nonjudgmental smoking-cessation support (it still benefits patients after diagnosis) and reinforce high-risk LDCT screening for others.
Therapeutic Communication Considerations
Lung cancer often carries stigma and guilt related to smoking — offer support without blame. Many patients face a poor prognosis; communicate honestly and compassionately, explore goals of care and advance directives, and introduce palliative care as added support, not “giving up.” Address breathlessness-related anxiety, which is frightening, with calm reassurance and effective symptom control.
Patient & Family Education
Teach the warning signs to report (new/changed cough, hemoptysis, worsening dyspnea, facial swelling). Reinforce smoking cessation and the value of LDCT screening for high-risk individuals. Explain breathing/energy-conservation techniques, home oxygen safety, treatment side effects, and when to seek urgent care. Discuss advance care planning and available support resources.
NCLEX Pearls
- ✦SCLC = aggressive, central, smoking-related, spreads early, chemo/radiation (not surgery); NSCLC = ~85%, can be resectable when localized.
- ✦Lung cancer is often diagnosed late — early disease is asymptomatic; smoking is the dominant risk.
- ✦Paraneoplastic syndromes (classic with SCLC): SIADH (hyponatremia), ectopic ACTH/Cushing's, hypercalcemia (PTHrP, squamous).
- ✦SVC syndrome = facial/neck/arm edema + JVD + dyspnea → oncologic emergency; elevate HOB and notify provider.
- ✦Low-dose CT (LDCT) is the recommended screening for high-risk older adults with a heavy smoking history.
- ✦Smoking cessation still helps after diagnosis — support it without judgment.
