Lung Elasticity Loss: Pulmonary Fibrosis vs. Lung Cancer - What's the Difference?

False. Loss of lung elasticity is the hallmark of pulmonary fibrosis (interstitial lung disease), where excessive collagen deposition stiffens the parenchyma, reducing compliance and gas exchange.

Lung cancer is a malignant neoplasm arising from bronchial epithelium or alveolar cells. It causes symptoms by local invasion, obstruction, metastasis, or paraneoplastic syndromes—not by diffuse elastic tissue loss.

Coexistence is possible (fibrosis increases lung cancer risk), but they are distinct pathologies.
