Whether the presence of 4 lung nodules is important or not needs to be judged separately for each nodule, mainly based on the examination results of the lung nodules to determine whether they are serious or not.
1. If the 4 lung nodules are small, all within 5mm, and the borders of the nodules are clear and the density is uniform, the nodules are generally due to benign lesions and are generally not serious.
2. If any of the lung nodules is large, larger than 5mm, and has an irregular border, such as lobulation, burrs and other conditions, or there is blood in the sputum and other uncomfortable symptoms, it is possible that the nodules are malignant, and need to consult a doctor in time for treatment, and follow up on a regular basis.
Patients suffering from lung nodules should pay attention to rest, eat a light and healthy diet, avoid smoking and alcohol, and also avoid prolonged exposure to smoking, second-hand smoke, dust and other environments. When lung nodules are found, it is recommended to go to the hospital in time to find out the cause of the disease and have regular follow-ups.
