No, it won't, provided you use a decent, supportive bra. The sports bras are designed for this very purpose, so I wouldn't worry about it. Remember, you're not doing the sort of running that the elite athletes are doing, and if those sports bras are good enough for them, then they'll work for you.
To Lara, same thing applies - that doesn't happen in elite women, who run maybe 15 hours a week, and so it won't happen in someone running 5 hours a week!
