17 w/ small breasts but my areolas are 3 inches in diameter. What can I expect from an Areola Reduction & when should I get it?

I am only 17, and ever since my breasts started developing I felt that they were unusual. My areolae are 3 inches in diameter! My breasts are even on the small side. I've been thinking a lot about surgery. My goal isn't to have perfect breasts, just to fix this one thing that has always bothered me. Should I get surgery sooner rather than later? I don't know if I'll get pregnant some day. Does the size of the reduction have an effect on healing time? And will the scar be noticeable once it's healed?
