If you have cold or bronchitis then you will have it for week or two and it will be accompanied by signs of infective ailments. If you start coughing little by little and if it lasts more than a few weeks then you should go and visit your doctor. Maybe you have some allergy or irritation but it is important to exclude the more serious cause like lung cancer.
Shortness of Breath
Shortness of breath can lead to lung or heart disease. You should go and see your doctor if you have difficulties that you haven’t had before while breathing or if you don’t have any heart-related issues.
One more sign of lung cancer can be dull or sharp pain in back, shoulder or chest areas. Chest pain is one of the less specific and most common sign in human medicine. First go and see your doctor before bringing conclusions by yourself, because the reason for this can be a psychological problem, heart issue, lung issue or some other causes.
