Any good advice on med school?

Well, I would love to be a Radiologist and since this is my last year in high school, I will be going to a community college for 2 years before transferring because it seems like a no brainer because I save time and lots of money and get the whole college thing down. Will going to community college hurt my chances of med school? And does it matter what I major in before I get into med school? Lets say a bachelors in business? and If I maintain a A-B in college what are my chances of getting into med school? Thanks
