Could my breasts have grown larger?

Maybe. Maybe not.

You need to quit fixating on your body.

Ditto the blue dinosaur.

Have you ever gotten treatment for your eating disorder?

34B on a 5 foot tall adult female doesn't sound very small to me.

What difference does it make what you breast size is, as long as you're healthy?

I've been male all my life--i feel confident in the statements i'm about to make. More than a mouthful is a waste. No mature man who says he loves you will care about the size of your breasts. If a man says he loves you, and he truly does, he will find your breasts to be the most beautiful he has ever seen, regardless of the size or shape. Any man who is worried about breast size needs to grow up, and you don't need someone like that.

Oh, and although i cannot speak with confidence about the feelings of lesbians, if that is what happens to matter to you, i rather suspect that another woman who truly loved you wouldn't care about breast size, either.

Based on my rather limited knowledge , I'd say "I doubt it, friend."

Breast composition seems to be something mostly genetic. This amount of fibrous tissue, this amount of fat. Water and not much else.

If it is mostly fatty tissue, you can swell them up as you gain weight.
Mostly fibrous, you end up with that situation of no matter how skinny you get your boobs stay nearly the same size!

Add to that a basically genetic disposition to where your fat will settle or not.

Guess I'm saying - since there is no bone or muscle in breasts, I doubt your early starvation would have effect on how large they would grow.

The early starvation more likely would worry to me to the growth of my bones, tissues, and brain.

Ain't no doctor, just going off what I have learned and observed about boobs and body.

I'm glad you are healthy.
