In fact, smoking is directly responsible for almost 90% of lung cancer.  DAMAGES TO THE RESPIRATORY TRACT: Smokers doubles their risk of lung disease, including lung cancer. But they also increase their risk of other respiratory illnesses. Lets study some of them: 1. Chronic bronchitis: This is a long-term (chronic) inflammation of the large airways (bronchi). Symptoms include coughing mucus over a long period. 2. Emphysema: This chronic lung condition affects the air sacs (alveoli) in the lungs. Symptoms include shortness of breath, coughing, fatigue, sleep and heart problems, weight loss, and depression. 3. Lung cancer: This is an abnormal growth of cells that can result in lumps, masses, or tumors. It may start in the lining of the bronchi, or other areas of the respiratory system. Smoking, including secondhand smoke, is the leading cause of lung cancer. 4. Other respiratory complications: It also increases the risk of other respiratory system cancers. These include cancer of the nose, sinuses, voice box, and throat."}
