Increased lung texture is usually not an initial symptom of cancer. Increased lung texture is commonly seen in diseases such as bronchiectasis, chronic bronchitis, and pulmonary edema. Pulmonary texture refers to radiating streaks of shadow that extend from the hilum to the periphery of the lung during chest imaging. There are many causes of pulmonary texture hyperintensities, which may be pathologic, physiologic, or due to errors in the examination, so reporting pulmonary texture hyperintensities in isolation is of little clinical value. The initial stage of cancer is usually asymptomatic, but when lung cancer progresses to a later stage, there are often occupying manifestations, combined with infection and acute and chronic inflammation around the tumor, when there may be corresponding lung texture changes, but also significant occupancy. After the increase of lung texture, it is recommended to perform high-resolution CT examination of the chest to clarify whether there is any disease in the lung, and after determining the cause, actively treat the primary disease, quit smoking as early as possible and exercise appropriately.
