The question of whether the pale nodules in the lungs are serious or not is related to the nature of the nodules. Thin nodules in the lungs are most often seen in inflammation, tuberculosis, tumors and other diseases. If it is inflammation, anti-inflammatory treatment can be given, the lesion can be absorbed and improved, and some lesions can be absorbed and improved by themselves. If it is tuberculosis, anti-tuberculosis drug treatment is needed, and the prognosis is generally better. These two categories of diseases are benign diseases, and the prognosis is generally better. If the lung nodules are caused by malignant tumors in the lungs, the lesions may grow over time and require surgical treatment, which is more serious. This is more serious because even after surgical treatment, the long-term effects are poorer, and intrapulmonary metastasis or systemic metastasis will often occur.
