Lung cancer is a leading cause of cancer-related mortality worldwide, characterized by the uncontrolled growth of abnormal cells in the lungs. It is primarily classified into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), each with distinct biological behaviors and treatment approaches. Risk factors for lung cancer include smoking, exposure to secondhand smoke, environmental pollutants, and genetic predispositions. The management of lung cancer has evolved significantly, incorporating a combination of surgical interventions, chemotherapy, radiation therapy, targeted therapies, and immunotherapy. Early detection and personalized treatment strategies are crucial for improving outcomes and survival rates. Understanding the advancements in lung cancer medicine is essential for patients and healthcare providers alike, as it empowers informed decision-making and enhances the potential for successful treatment.
