[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Since you are smoker, possibility of bronchitis, lung infection and lung cancer is high. All these can cause similar symptoms. But lung cancer is less likely because of your age. But better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray 3. PUT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection and lung cancer. PFT is must for the diagnosis of bronchitis. You may need inhaled bronchodilators, inhaled corticosteroid (ICS) and antibiotics according to the cause. You need to quit smoking as soon as possible. So consult pulmonologist and discuss all these. Hope I have solved your query. Wish you good health. Thanks.
