Lung nodules 0.6cm may not require treatment, but it also depends on the specific manifestations of the nodule tissue to make a judgment. Lung nodules of 0.6cm are relatively small, and generally if there are no obvious uncomfortable symptoms and no obvious malignant features, regular rechecks are sufficient and no special treatment is needed. However, some lung nodules may have blurred borders or burr signs, and sometimes rapidly increase in size beyond 0.6cm in a short period of time, which should be considered as malignant and require timely examination and early surgical resection. When lung nodule 0.6cm occurs, it is necessary to prevent recurrent respiratory infections and inhalation of large amounts of dust, do a good job of protection, and regularly go to the hospital for review, and if there are obvious changes in the nodule in the late stage, it is necessary to consult a doctor for treatment in a timely manner.
