Is pleural thickening an early sign of lung cancer?

Hello, pleural thickening is not necessarily an early sign of liver cancer. It can be observed in conditions such as pleuritis, tuberculous pleuritis, and malignant pleural mesothelioma—and may even occur in healthy individuals. Pleural thickening typically results from untreated or inadequately drained pleural effusion. When pleural fluid remains in the pleural cavity for an extended period, it irritates the pleura, leading to thickening. Additionally, prolonged accumulation of pleural fluid can cause fibrin deposition and adhesion to the pleura, further contributing to pleural thickening. We hope the above information is helpful to you. Wishing you a happy and healthy life!
