What should an international patient prepare before traveling?

International patients should secure a medical visa (S visa) through a Chinese embassy or consulate, often facilitated by the hospital's international department. Bring all medical records, including CT scans, pulmonary function tests, and biopsy results, with English translations. Arrange for a professional medical interpreter if needed, and plan for a stay of at least 2–4 weeks for initial evaluation and treatment. Confirm follow-up care coordination with your home pulmonologist before departure.
