Whether a pulmonary nodule will continue to grow depends mainly on the nature of the nodule. If the nodule is benign, it is usually inflammatory, and after standardized anti-inflammatory treatment, the nodule can be dissipated and absorbed. Even if the nodules are caused by tuberculosis, they are mostly proliferative and benign, and will not change or grow. In the case of early malignant nodules, the size of the nodule and the changes in the nodule should be considered. If the nodule is smaller than 5mm, it can be similar to a benign nodule in the early stage, and it is not easy to determine whether the nodule will grow and change. However, if the nodule is suggestive of lobulation, short burr, pleural pulling sign, pleural depression sign, etc., and shows growth and change, it is necessary to be highly alert to the possibility of early lung cancer. Enhanced CT examination of the chest can be given, and puncture of the chest nodule, cytology and histology can be given when necessary to evaluate whether it is early lung cancer. In conclusion, when determining whether an early lung nodule will grow or not, if the nodule is benign, it will not grow. If the nodule is malignant and shows growth changes, it is likely to grow at this time.
