Causes of Pleural Thickening. Pleural thickening is a condition of the lungs that is most often caused by the long term exposure and inhalation of asbestos particles which then settle on the pleura, or pleural membrane (the thin area surrounding the lungs) causing the area to thicken, calcify and/or scar.
A pleural effusion is a buildup of extra fluid in the space between the lungs and the chest wall. This area is called the pleural space. About half of people with cancer develop a pleural effusion. When cancer grows in the pleural space, it causes a malignant pleural effusion. This condition is a sign that the cancer has spread, or metastasized, to other areas of the body. Common causes of malignant pleural effusion are lymphoma and cancers of the breast, lung, and ovary. Although a malignant pleural effusion is treatable, it can be a serious, potentially life-threatening condition.
