Non-malignant pleural disease
Non-malignant pleural disease is a non cancerous condition affecting the outer lining of the lung (the pleura). It includes two forms of disease: diffuse pleural thickening and the less serious pleural plaques. A substantial number of cases continue to occur each year in Great Britain, mainly due to workplace asbestos exposures many years ago.
The latest information shows:
- There were 425 new cases of pleural thickening assessed for Industrial Injuries Disablement Benefit in 2014 (IIDB).
- The annual number has been fairly constant over the last 10 years, with an average of around 430 new cases per year (IIDB).
- An estimated 580 new cases of non-malignant pleural disease mainly caused by asbestos were reported by chest physicians in 2014. A substantial proportion of these were cases of pleural plaques (THOR).
- Pleural plaques are usually symptomless and are often identified in the THOR scheme when individuals have chest x-rays for other conditions.
- For these reasons, there are likely to be substantially more individuals in the population with pleural plaques than those identified by chest physicians.
