The incidence of pulmonary nodules as a whole show an increasing trend. The pulmonary nodules can be divided into pure wool hyaline, part of the solid nodules and solid nodules. There are also sorted of as malignant and benign into independence malignant lung nodules and benign lung nodules. The independence malignant lung nodules is based on the early lung adenocarcinoma. A part of early lung cancer patients who are already via part of liquid biopsy’s and lung biopsy’s diagnosis will accept the operative treatment. But, for another part of patients who are inoperable, we will adopt body stereotactic radiotherapy. And some uncertain diagnosis patients, we should follow-up with them regularly according to their velocity of growth, iconography, the high danger. If the pulmonary nodule’s volume is expanding and the density is increasing. We should give them an operative treatment during follow-up with them.
