Hematologists

Ok! This is kind of a lot so I’m sorry ahead of time. But a little bit about me. I am a military spouse whose husband is stationed overseas. I don’t have a opportunity to do labs/hands on stuff. Which I know is needed. But I’m 22....almost 23. With a 1 year old. I really want to start going to school. Specifically to be a hematologists. Best degree is major in? What to get out of the way now for classes? Any tips, advice? Thank you!!!💛
