From my experience, it would definitely not be frowned upon to pursue a minor or double major in Russian. Not only would this enrich your life personally, as you'd be able to speak with extended family, it could help you professionally as well. Learning a language could open doors to international opportunities, and classes in the arts (such as language) are a good balance to science courses.
It sounds like your goal is to go to medical school and become a doctor. If this is the case, I would recommend you sit down with your current high school guidance counselor and discuss your options. Medical schools have strict pre-requisites you'll be required to complete to get admitted. Your guidance counselor could help you choose a Science major that will meet these requirements. When you start your under-graduate schooling, you may also find it helpful to sit down with your college guidance counselor. They will be able to sit down with you and help you choose courses that will help you meet your goals, as well as introduce you to individuals and activities that will help you accomplish your goals.
