Dry cough is a very common symptom in clinical practice, caused by many factors which are also very complex. Some patients might clearly have lung cancer. Due to the presence of lung cancer lesions, patients can experience irritating dry cough as well as symptoms like hemoptysis, chest pain, and chest tightness. It is possible that some patients do not exhibit symptoms of dry cough, perhaps due to other causes. Therefore, for dry cough, we need to identify if it is caused by lung cancer, as it often requires surgical treatment to control the symptoms. Some patients with minor lung cancer who experience dry cough might be able to control it with appropriate medications. However, to effectively control symptoms of dry cough caused by lung cancer, surgical removal is generally necessary and is the ultimate treatment plan.
