AbstractLung cancer is the second most common cancer in men and women in the United States; however, it remains the leading cause of cancer-related death in the United States and worldwide. The most common but nonspecific symptom of lung cancer is cough. Associated symptoms, including hemoptysis or shortness of breath, or systemic symptoms, including anorexia or weight loss, greatly increase the likelihood of having lung cancer. Referral to a multidisciplinary lung cancer team, imaging, and confirmation through sputum cytology, thoracentesis, fine-needle aspiration, or mediastinoscopy are recommended. If lung cancer is confirmed, treatment options vary based on staging, histology, immunotherapy biomarker testing, and patient health status. Treatments include surgical resection, immunotherapy, chemotherapy, and/or radiotherapy. Family physicians should focus on primary prevention of lung cancer by encouraging tobacco cessation and early recognition by screening at-risk individuals and following guidelines for pulmonary nodules. As of 2021, the U.S. Preventive Services Task Force recommends annual lung cancer screening using low-dose computed tomography starting at 50 years of age in patients with a 20 pack-year history.
