What should I do if I find small nodules on my lungs during a physical examination

Small pulmonary nodules discovered during physical examination need to be treated through a combination of regular follow-up and medical intervention. The medical treatment of pulmonary nodules usually depends on the size, morphological characteristics, and risk factors of the patient. For small nodules with a diameter less than 6 millimeters, it is recommended to undergo low-dose CT re examination annually. Nodules with a diameter between 6-8 millimeters need to be rechecked every 6 months. When the diameter of the nodule exceeds 8 millimeters, more frequent follow-up or consideration of PET-CT examination may be required. The malignancy probability of solid nodules is usually lower than that of partially solid or ground glass nodules. Nodules with malignant features such as spiculation and lobulated edges require shortened follow-up intervals. Elderly patients or high-risk groups with a long-term smoking history require closer monitoring. When nodules are found to have increased size or morphological changes during follow-up, it may be necessary to consider CT guided biopsy or thoracoscopic surgical resection.

It is recommended to maintain a regular schedule and avoid smoking and exposure to secondhand smoke. Pay attention to a balanced diet and supplement with high-quality protein and vitamins in moderation. Maintain moderate exercise to enhance lung function. If symptoms such as coughing, hemoptysis, and chest pain occur, seek medical attention promptly. Pay attention to monitoring temperature changes in daily life to avoid respiratory infections. Protective measures should be taken when going out in high pollution weather. Follow the doctor's advice for regular check ups and do not interrupt the follow-up plan on your own.
