Chest X-ray suggests that small nodules in both lungs are not necessarily pneumoconiosis, there are inflammation, tuberculosis, tumor and other possibilities. 1. Inflammation: If the nodules in both lungs are small and regular in shape, and at the same time, the patient has a history of previous infection, we need to be highly alert to the possibility of inflammation, and we can further improve the laboratory examination, and then follow the doctor’s instructions to take oral antibiotics, such as moxifloxacin after diagnosis. 2. Tuberculosis: if the patient has fever, lethargy, fatigue and other symptoms at the same time, or has a history of contact with tuberculosis patients, the patient can further improve the chest CT, PPD and other examinations, and take anti-tuberculosis drugs such as rifampicin orally under the guidance of the doctor. 3. Tumor: if the patient has tumor in other parts of the body, and at the same time, there are multiple small nodules in both lungs, it is necessary to be alert to the possibility of metastasis, which can be further perfected by chest CT, whole-body bone scanning and other examinations. If there are multiple nodules in both lungs, it is recommended to consult a doctor and actively cooperate with the physician for treatment.
