The clinical symptoms of benign tumors of the lungs are relatively few, sometimes we can’t even observe the obvious clinical symptoms or signs, but there are some cases of lung infection, as well as coughing, hoarseness (mute, unable to make a sound), hemoptysis and other symptoms. Generally, the survival of patients with benign lung tumors is relatively good. In addition, because benign lung tumors grow very slowly, there are fewer clinical symptoms associated with the compression of the tumor on the surrounding tissues. A few patients may have clinical symptoms due to large tumor, adjacent bronchial tubes or other unknown reasons, the most common cough and non-specific chest pain, but also chest tightness, hemoptysis sputum, fatigue and so on. If the patients once found that they have lung tumors, they must seek medical treatment in time, actively cooperate with the physician to treat the tumor, and keep a good mind and mood.
