What should an international patient prepare before traveling?

Obtain a valid medical visa (S1 or S2) and bring all prior medical records, including pathology slides, imaging, and lab results (translated into Chinese if possible). Arrange for a professional medical interpreter, as English-speaking staff may be limited outside major international centers. Plan for a minimum stay of 2–3 months for initial treatment and ensure you have a local contact or case manager for follow-up care coordination. Also, secure comprehensive travel health insurance covering cancer treatment.
