Asbestosis of the lung is associated with all of the following except –
**Asbestosis of the Lung**
**Core Concept**
Asbestosis is a chronic inflammatory and fibrotic medical condition affecting the tissue of the lungs. It is caused by the inhalation and retention of asbestos fibers, leading to a progressive and often fatal disease.
**Why the Correct Answer is Right**
Asbestosis is associated with the inhalation of asbestos fibers, which cause chronic inflammation and fibrosis in the lung tissue. The disease is characterized by the formation of scar tissue in the lungs, leading to impaired lung function and respiratory symptoms. The pathogenesis of asbestosis involves the activation of macrophages, which release pro-inflammatory cytokines and growth factors, leading to the proliferation of fibroblasts and the deposition of collagen.
**Why Each Wrong Option is Incorrect**
**Option A:**
Asbestosis is indeed associated with an increased risk of lung cancer, particularly mesothelioma, a rare and aggressive cancer of the pleura.
**Option B:**
Asbestosis is associated with an increased risk of pleural plaques, which are areas of fibrosis in the pleura that can be detected on chest X-rays or CT scans.
**Option C:**
Asbestosis is associated with an increased risk of chronic obstructive pulmonary disease (COPD), a condition characterized by airflow limitation and impaired lung function.
**Clinical Pearl / High-Yield Fact**
Asbestosis is a preventable disease, and the risk of developing the disease can be significantly reduced by avoiding exposure to asbestos fibers.
**Correct Answer:** D.
