How to go to college for less?

I'm only in 9th grade at the moment, but after taking the PSAT I've been looking at colleges to attend. Unfortunately, a majority of the colleges I would like to go to cost quite a bit of money. The one I'm thinking about at the moment costs (in total) about $56,000. I feel like that's a ridiculous amount of money to pay for college, but like I said, all of the colleges I'm considering cost somewhere in that range. It's not that my parents can't exactly afford that much money (my dad's a lawyer and my mom owns her own business that does really well). I just don't feel like I should be asking them to shell out that much money for four years in a row. I could take out a loan, but since I'm planning on going to medical school afterwards, I'd have one huge loan. I want a way to be able to pay for the majority of my college. I'm thinking about majoring in either Biology or Biochemistry at the moment. Also, I'll play clarinet in college band, but I won't be going to school for the sole purpose of playing my instrument. My question now is: What scholarship opportunities can I take advantage of to lessen the cost of college?
