The symptoms with pleural mesothelioma are primarily respiratory. In the majority of patients the first two symptoms are chest pains pretty strong, and dyspnea (difficulty breathing). In approximately 30 percent of the cases, this difficulty breathing is given in a set of pleural effusions but without the pain in the chest.
Pleural effusions are your own symptoms, but typically these are responsible of chest pain and shortness of breath. This happens when it accumulates too much fluid in the pleural cavity.
In stages III and IV of pleural mesothelioma, the patients may notice the following symptoms:
Hoarseness at the time of speaking
Whistles at the time of coughing
Difficulty in swallowing
If the tumors grow large enough, patients may also notice lumps in the chest or near the shoulders.
