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. Lung texture is a radiating stripe of shadow extending from the hilum to the periphery of the lung during chest imaging. There are many causes of lung texture hyperintensities, which may be pathological, physiological or due to errors in the examination, so the phenomenon of lung texture hyperintensities alone is of little value for clinical diagnosis. While there are usually no obvious symptoms in the early stage of cancer, patients with lung cancer progressing to the later stage often have occupational manifestations, combined with infection and acute and chronic inflammation around the tumor. At this time, there may be corresponding lung texture changes, but at the same time, there will also be obvious occupancy. After the appearance of increased lung texture, patients are recommended to have a high-resolution CT examination of the chest to clarify whether there is any disease in the lung. If the diagnosis is confirmed, the patient should actively treat the primary disease, quit smoking as soon as possible, and take appropriate exercise.
