What does "old pulmonary nodule" mean?

Old pulmonary nodules are scar tissues left in the lungs after previous infections, inflammation, or tuberculosis have healed. They are mostly benign and asymptomatic, posing no direct threat to health. However, regular imaging examinations are still necessary to monitor any changes. If abnormal symptoms such as chest pain, coughing up blood, or shortness of breath occur, prompt medical consultation at a respiratory department of a hospital is recommended.

The formation of these nodules is often associated with prior lung infections, such as pneumonia or pulmonary tuberculosis. During the healing process, fibrotic or calcified lesions may develop in the lung tissue. These lesions are typically stable and unlikely to progress. Most patients do not require specific treatment but should follow their doctor's advice for periodic follow-up based on the nodule's size and appearance. In rare cases where the nodule has atypical features, further tests may be needed to confirm the diagnosis.

For daily care, maintain a regular sleep schedule and avoid staying up late. Quit smoking and avoid secondhand smoke and environments with dust or air pollution. Engage in mild exercises such as walking, maintain emotional stability, and avoid excessive anxiety or worry. Practicing scientific self-care can help reduce the risk of pulmonary complications.
