Pleura

aka pleural, pleural cavity, pleural space, extrapleural, pleurectomy, pleurectomy/decortication, pleural metastases

The two-layered lining around each lung. Mesothelioma grows from it, lung and breast cancers spread to it, and fluid collecting between its layers causes breathlessness.

The visceral pleura covers the lung and the parietal pleura lines the chest wall; the potential space between them fills with a malignant pleural effusion in advanced lung, breast and ovarian cancers and lymphoma. Malignant pleural mesothelioma, almost always from asbestos, spreads along the pleural surface; its surgery ranges from extrapleural pneumonectomy (abandoned after MARS 1) to pleurectomy/decortication (questioned by MARS 2). Pleural invasion also upstages lung cancer.
