A lung nodule is a round or oval mass of cells thats smaller than 30 millimeters (mm) (1.2 inches) in diameter. Results: GGO is a nonspecific radiologic finding showing a hazy opacity without blocking underlying pulmonary vessels or bronchial structures. A stable opacity over time and many X-rays is more likely to be something benign, perhaps scarring from prior infection. Vaping can also cause alveolar hemorrhage.
