<\/span>3. What environmental factors can cause lung cancer?<\/b><\/span><\/h3>\nAsbestos, industrial chemicals, and prolonged exposure to pollutants may increase risk. Radon exposure is significant in some regions but less common in India.<\/P><\/p>\n
<\/span>4. How can I distinguish between symptoms of lung cancer and those of a regular cough or infection?<\/b><\/span><\/h3>\nPersistent or worsening symptoms, or a cough accompanied by blood, should be evaluated by a specialist.<\/P><\/p>\n
<\/span>5. When should I see a doctor for lung cancer symptoms?<\/b><\/span><\/h3>\nPrompt consultation is advised for persistent cough, shortness of breath, chest pain, or unexplained weight loss.<\/P><\/p>\n
