Is patchy ground-glass shadow cancer

Patchy ground-glass opacity is a common imaging manifestation in CT examination of lung. Clinically, patchy ground-glass opacity cannot be regarded as malignant tumor or cancer. Clinically, patchy ground-glass opacity less than 6mm is mostly benign. For ground-glass opacity larger than 6mm and smaller than 15mm, it is necessary to make a good differential diagnosis, observe the imaging changes, whether there is a gradual increase trend, whether there is a nodular change, and the patchy ground-glass opacity gradually has solid changes, split-like changes, accompanied by spiculation signs, pleural traction signs and other malignant manifestations. However, the final criteria for determining whether cancer is still based on pathology.
