What should an international patient prepare before traveling?

Obtain a valid passport and medical visa (S2 or M visa) for treatment in China. Arrange for a certified medical interpreter if needed, though many top hospitals provide interpretation services. Gather all medical records, including pathology slides, imaging, and prior treatment history, and have them translated into Chinese or English. Plan for a stay of at least 4–6 weeks to cover initial treatment and follow-up, and ensure you have travel health insurance that covers medical evacuation.
