Pneumonectomy is a surgical procedure that involves the removal of an entire lung. This operation is typically performed to treat conditions such as lung cancer, severe lung infections, or other serious lung diseases. The goal is to eliminate the diseased tissue and improve the patient's overall health. After a pneumonectomy, patients may need time to recover and adapt to having one lung. They may experience changes in breathing and lung function, but many can lead active lives with proper rehabilitation and care. Regular follow-ups with healthcare providers are essential for monitoring recovery and managing any complications.
