The original nodule in the lung is increasing in size, indicating that the nodule is progressing and is not completely stable, and this should be actively diagnosed and treated. The most important thing to look for in the differential diagnosis is whether it is an inflammatory problem or an overgrowth, which may have the possibility of malignant transformation, and this can be done in the hospital. The treatment of Western medicine is only possible after the diagnosis is confirmed, so the process of confirmation may be longer. Because the treatment of Chinese medicine to clear the lung does not have to rely on Western medicine to complete the diagnosis, the CT examination of Western medicine to find enlarged nodules is itself an extension of the four diagnoses of Chinese medicine: looking, smelling, asking and cutting, which can be used as an aid to the diagnosis of looking to carry out the treatment of Chinese medicine. In terms of TCM, nodules in the lung are generally phlegm and dampness, which can be a combination of phlegm and qi, phlegm and stasis, or simply phlegm blocking the lung. Doing Chinese medicine to clear the lung can prevent the lung nodules from progressing too fast, to buy time for western medical examination and to find the targeted treatment directly.
