Hi - While it's probably not the case with most women, it's not abnormal for one breast to be bigger than the other. Now, if this has happened all of a sudden (rather than your breasts naturally being two different sizes), probably best to call the doctor to see what's up. Good luck - PJH

I think it's completely normal for one breast to be larger - it's just as one foot is slightly bigger.  As you use the muscles on your dominant side (like if you're right handed) then most things on that side of you body will be slightly bigger cause you work them more.  But the difference should be small, and it would be something you've always had - not something that just suddenly appeared.

if it is something you feel just came about one day then I would highly suggest checking with your doctor, but if it is something you've always had I'm sure you'll find that most people can relate cause they've noticed simular differences.

Best of luck to you!

Yes, I have heard that it is normal.  My right one is larger than may left, bras never fit right, it usually bulges out of the bra on that side.  Don't worry I have had it like this for 56 years.
