Asbestosis Disease

Part of the Asbestos / Mesothelioma investigation

The short answer

Asbestosis is a non-cancerous progressive lung fibrosis caused by asbestos exposure. While less severe than mesothelioma, it causes significant respiratory disability and qualifies for asbestos trust fund compensation and disability claims.

It also substantially increases the risk of developing mesothelioma or lung cancer.

What Is Asbestosis?

Asbestosis is a chronic, progressive inflammatory and fibrotic disease of the lung parenchyma caused by the accumulation of asbestos fibers in the lung tissue. Unlike mesothelioma (which affects the pleural lining) or lung cancer (which involves malignant lung tissue transformation), asbestosis causes progressive scarring (fibrosis) of the lung tissue itself, gradually reducing lung function and gas exchange capacity. It typically develops after prolonged, heavy asbestos exposure — most commonly in workers with 10 or more years of occupational asbestos exposure at elevated concentrations. Asbestosis does not become mesothelioma, but its presence dramatically increases the risk of developing mesothelioma or asbestos-related lung cancer, and it may be a warning signal requiring vigilant cancer surveillance.

Disability Claims and Legal Compensation

Asbestosis is compensable through asbestos trust funds (typically Level I-IV disease, with payment percentages lower than mesothelioma), workers' compensation for occupational lung disease, and Social Security Disability Insurance if the condition prevents sustained employment. Veterans with documented in-service asbestos exposure who develop asbestosis qualify for VA disability compensation proportional to their pulmonary function impairment rating. Some asbestosis claimants later develop mesothelioma and can then upgrade their claims to the higher mesothelioma compensation level.

Frequently Asked Questions

Mesothelioma is a cancer of the mesothelium — the thin membrane lining the lungs (pleura), abdomen (peritoneum), or heart (pericardium). It is distinct from lung cancer, which originates in the lung tissue itself. Mesothelioma is caused almost exclusively by asbestos exposure and does not arise from smoking. Lung cancer, while also caused by asbestos in some cases, is far more commonly caused by tobacco smoking. Both are compensable through asbestos trust funds and litigation, but mesothelioma claims typically produce higher compensation because the disease is more directly and singularly attributable to asbestos.
