What should an international patient prepare before traveling?

Obtain a valid passport and medical visa (S2 or M visa) for China, and gather all medical records, including imaging scans and pathology reports, with English translations. Arrange for a professional medical interpreter or use hospital-provided services, and plan for a companion if needed. Confirm follow-up care with your home doctor and discuss post-treatment monitoring, as some patients may require periodic scans or additional therapy after returning.
