text: hi,wat do i major in to become a surgeon.?   assumed: in the u.s.  your major makes no difference.  many doctors, including surgeons majored in a field other than science such as business, philosophy, etc.  having said that, the mcat, which is a test required by virtually all u.s. medical schools, contains questions on both physical sciences as well as life sciences.  in addition, most medical schools require a list of basic coursework in sciences.  so while you do not need to major in a science, you will need to take a number of science courses.    finally, your major in your undergraduate program will have no impact on what happens after medical school.  if you want to be a surgeon, you need to do well in mmdical school and of course there are different areas of surgery that are more difficult to get into than others.  so worry about getting into medical school first: good mcat score, high gpa (3.5 or higher), and of course your unique and diverse persona.
