I am only 11
And I have big breast
I'm skinie
But my breast are huge
No one of my friends have any :(
I want flat breast not huge ones
I don't want sergary cause I'm 11
What should I do?

At 11 you could not get any surgery anyway. There is nothing you can do. Your must just be maturing faster than your friends, over the next few years, the others will be changing also. It is just a part of life.

Sorry, nothing you can do at all. Make sure you have a well fitted bra.
