Pleural mesothelioma accounts for about 75 percent of all mesothelioma cases. Like other types of mesothelioma, this particular form of the disease gets its name because of where it is formed — in the pleura, a soft tissue that surrounds the lungs. In almost all cases, pleural mesothelioma is caused by asbestos exposure.
The first symptoms of pleural mesothelioma typically include chest pain and shortness of breath. You may experience no symptoms at all in the first few stages of the cancer’s progression.
Symptoms of pleural mesothelioma include persistent dry or raspy cough, coughing up blood (hemoptysis), shortness of breath (dyspnea), and difficulty swallowing (dysphagia). There are four stages of mesothelioma that doctors use to describe how far the cancer has progressed. For many people, unfortunately, symptoms are not noticeable until the cancer is in a later stage — stage III or IV.
Asbestos fibers can cause excess fluid to build up between the two layers of the pleura, a condition called pleural effusion. While a little fluid in your pleural space is important, too much can make breathing difficult. The extra fluid puts pressure on the lungs, causing chest pain that gets worse when you cough or take deep breaths.
