<p>I am interested in being a practicing physician but because of growing interests in various cultures, languages, and international health disparities, I want to pursue a career as a physician that works around the world: an ambassador for WHO or Doctors without Borders, etc.</p>
<p>What are some majors that I can pursue that entails my goals but at the same time isn't so broad as international relations/affairs (which doesn't really involve medicine/health sciences)?</p>
<p>Majoring in a language or languages if a international studies major is out of the question may be worthwhile.</p>
<p>how about public health major</p>
<p>I have very close interests! I really love biology, math, and foreign languages. Those sound like great jobs. I know you can work as a doctor without borders with almost any kind of medical degree. They need surgeons, physician assistants, nurses, etc. So just pursue whatever type of medical career you want. Of course, to get the positions you want, you’re going to have to work your way up the ladder. I have a few suggestions for you.
You should get an undergraduate degree in anything that fascinates you, like international politics, humanities, or a foreign language. And then for graduate school, go to whatever MEDICAL job you think you would like to do (like med school, anesthesiology, physician’s assistant school, etc). You don’t have to be 100% sure on what kind of grad school you want to attend. That will be more important later, and for now, what matters most is your undergrad major.
And just because you have an interest does not mean you have to major (or minor) in it. You can just take whatever classes in it you want. Like, you could get some business/political degree, but also take classes in humanities and foreign langauges. Of course, no matter what degree you get, its important to take some classes in biology/health science because that’s your main goal. And remember that many grad schools have prerequisite classes. If you take your basic pre-med prereqs (like bio 1 & 2, chem 1 & 2, organic chem 1 & 2, and calc 1), then you’ll pretty much be good for most types of medical grad schools. Just do your reserach 
Of course, you could also major in biology/science and take classes in humanities/langauges. Whatever you feel is the best as far as undergrad school goes. Remember that undergraduate school is the time to take classes in ANY subject you like. You might not be able to do that in grad/med school. Plus, med schools like applicants that are well rounded, so if anything, having a major in humanities or politics will boost your chances.
If you want to be a nurse, then you’re going to have to major in nursing for undergrad, but you could also take classes in your other interests as well.
There are many different possibilites to reach your goal 
This may help you as far as meeting requirements for doctors without borders goes:
