Benign pulmonary nodules usually have no significant impact on the patient’s life expectancy, and patients only need to be reviewed regularly. Benign pulmonary nodules are relatively small, usually less than 6 mm in diameter, and are commonly seen in diseases such as inflammatory pseudotumors, pulmonary sclerosing hemangiomas, tuberculosis bulbs, and can also be caused by long-term smoking. Benign pulmonary nodules usually do not require treatment and do not affect the patient’s life expectancy, so patients should pay attention to regular review. If, after a period of observation, nodules are found to grow and have a tendency to become malignant, surgery should be performed promptly. Patients with benign pulmonary nodules must pay attention to good habits in daily life, quit bad habits, avoid smoking and alcohol, avoid spicy and stimulating food, regular rest and rest, and ensure sufficient sleep. Adults are advised to exercise properly, such as doing chest expansion exercises, swimming and other aerobic exercises, which can enhance physical fitness and reduce the occurrence of pulmonary nodules.
