What symptoms about a centrally located tumor would produce?

Coughing

Centrally located pulmonary tumors are found in the upper airway (vocal cords) and usually obstruct airflow. producing such symptoms as coughing. wheezing. and stridor. Small cell tumors tend to be located in the lower airways and often cause hemoptysis. As the tumor invades the pleural space. it may cause pleuritic pain. Pancoast tumors that occur in the apices may cause shoulder pain.
