What does multiple nodules in both lungs mean, and is it serious?

Generally, multiple nodules in both lungs refer to several small round or oval shadowed areas in the lungs. The severity depends on the nature of the nodules. If they are benign, the condition is usually not serious; if malignant, it tends to be more severe. Seek medical attention promptly if any symptoms occur. Specific analysis is as follows:

Multiples nodules in both lungs caused by benign conditions such as lung infections, tuberculosis, or sarcoidosis are typically not severe. With active treatment, these nodules often shrink or disappear. Regular follow-up examinations are recommended to monitor changes in the nodules.

Multiple nodules in both lungs resulting from primary lung cancer or metastatic tumors are generally more serious, especially when accompanied by symptoms such as cough, sputum production, hemoptysis (coughing up blood), and fever. Malignant tumors may grow rapidly and spread to other parts of the body, posing a threat to life. Treatment under a doctor's guidance—such as thoracoscopic surgery or open thoracic surgery—is recommended.

It is also recommended to maintain good lifestyle habits, including a healthy diet and moderate exercise, which can help strengthen the body's overall condition.
