What is involved in bringing in a relative from another country for cancer treatment?

Research: You would need to do a lot of research first as to who would accept the treatment of the patient, costs of treatments, who will pay (insurance or not?). Would need detailed medical records of the patient as to what has already been done. Would need to know if there is any treatment here that would benefit the patient, as you would want to avoid the trip if there is no treatment available.
