| Global Impact | - Lung cancer causes nearly 1 in 5 cancer-related deaths worldwide. - Many cases are detected late due to lack of awareness, late screening, and stigma. |
| World Lung Cancer Day | - Observed annually on August 1 since 2012. - Initiated by Forum of International Respiratory Societies (FIRS) and advocacy groups. - Aims to promote awareness, early detection, and prevention. |
| Types of Lung Cancer | - Non-Small Cell Lung Cancer (NSCLC): Most common (80-85% of cases), slower-growing. - Small Cell Lung Cancer (SCLC): Less common (10-15%), aggressive, strongly linked to smoking. |
| Risk Factors | - Smoking & second-hand smoke (primary cause). - Air pollution (PM2.5, nitrogen dioxide). - Occupational hazards (asbestos, silica, arsenic). - Radon gas exposure. - Genetic predisposition. |
| Common Symptoms | - Persistent cough, shortness of breath, chest pain, unexplained weight loss, coughing up blood, fatigue, hoarseness, recurring infections. |
| Diagnostic Methods | - Chest X-rays, CT/PET-CT scans, bronchoscopy, biopsies, sputum cytology. |
| Treatment Options | - Surgery (lobectomy, pneumonectomy). - Chemotherapy, radiotherapy, targeted therapy, immunotherapy, palliative care. |
| Recent Advances | - Molecular/genetic testing for personalized treatment. - Immunotherapy improvements. - Precision radiotherapy (SBRT). - Minimally invasive surgeries. |
| Common Myths | - Myth: Only smokers get lung cancer. Reality: Non-smokers affected too. - Myth: Always shows early symptoms. Reality: Often asymptomatic initially. - Myth: No hope after diagnosis. Reality: Advances improve survival. |
