Inclusion Criteria

Inclusion Criteria: 1. Age 18 years or older. 2. Clinically or pathologically diagnosed with lung cancer. 3. Undergoing lung cancer-related thoracic surgery. 4. Surgical procedures may include video-assisted thoracoscopic surgery, robot-assisted thoracic surgery, or open thoracic surgery. 5.

Provides written informed consent. Exclusion Criteria: 1. Patients receiving non-surgical treatment only. 2. Patients undergoing bronchoscopy, percutaneous biopsy, or other non-surgical diagnostic or therapeutic procedures only. 3. Clinically unstable after surgery and unable to participate in symptom assessment or recovery management. 4. Requiring prolonged intensive care unit treatment, continuous advanced life support, or continuous intensive medical management. 5. Severe cognitive impairment, psychiatric disorder, language communication disorder, or other conditions that preclude completion of study assessments. 6. Unable to use a smartphone or study device and without a caregiver who can assist with use. 7. Currently participating in another interventional clinical study that may affect the primary outcome of this trial. 8.
