there are treatments your doctor can provide you with if you so wish

I have severe gyno. It's weird cause I have flat chest but areolas look like pointy balls.

At your.next check-up. Have your doctor prescribe some medicine to help take care of that

If you are over-weight it can cause more estrogen to be produced, causing an increase in breast size, it can also be caused by puberty hormones being all over the place at the beginning of puberty, your body will adjust and hormones will balance out. If you are concerned go see he doctor for advice
