Rapid growth of lung nodules does not necessarily indicate a neoplastic lesion; other lesions such as peripheral exudates or increased caseous tissue can also cause lung nodules to increase in size, and rapid growth simply indicates that the size of the nodule has increased significantly over a short period of time.
Lung nodules clinically include tumors and infectious lesions in the lungs. The short-term increase in the size of lung nodules may be due to histiocytosis, or an increase in peripheral exudate or caseous tissue. If the nodule is caused by histiocytosis, it should be considered as a tumor, while the increase of surrounding exudate or caseous tissue may be caused by mycobacteria or tuberculosis.
Rapid growth of lung nodules is not necessarily a tumor, the details need to be combined with the morphology of the nodule itself, the edge, the relationship with the surrounding tissues, and clinical history to make a comprehensive judgment, but also through blood tests and puncture biopsy for final diagnosis.
It is recommended that the patient should go to the hospital for diagnosis and standardized treatment under the guidance of the clinician.
