MY FATHER

Hi, my name is Lijun. I am an international student in the US now. My father was diagnosized as esophageal cancer last month. He was 55 years old. He could not accept surgery because the doctor said the cancer lies in the upper part of his esophasus, and also because my father has heart disease. He is receiving radiation/chemotherapy now. I just wonder whether I can buy advanced medicine in the US. Will a description from a doctor in my homecountry be ok? Look forward to your reply as soon as possible. I do not want to loose my father.
