As others said, you can major in anything you like. You just need to fit the med prerequisites into your schedule as well. Bio and biochem have the most overlap with the prerequisites so those are popular with premeds… it’s easier to fit into the schedule.
When you meet with your advisor you can map out a four year plan of major+premed classes. If you would like to study abroad, discuss that as well. Some schools will not give credit for major classes taken at other institutions or will only accept them from a limited number of partner institutions. My premed kid changed her major from biochem to more easily accommodate a semester abroad. That may not be an issue at your school but ask to be sure.
Whatever major you choose, it should be one you are interested in because you’re more likely to have a high GPA. And consider the career potential of the major if you do not get accepted to med school.
