Confused About My Breast Development

I'm a 20 year old girl with size 30E breasts (which makes them sound a lot bigger than they are) and am uncertain about whether or not I'm at the end of their development.

I got my period late (like around end of 9th grade) and was completely flat at the time. We attributed both of these things to the fact that I have been very skinny (less than the 1% percentile weight for my height) since I was a baby and have had extreme difficulty gaining weight. (Doctor's placed me on some medications to help me gain weight and I've since then reached an almost normal level of 105 lbs at 5'3'' which is in the 15 percentile area). However, when I reached about 17 my breasts suddenly jumped to a 30B and paused for a period. I noticed that they still had the areola slightly separated on a mound that was characteristic of stage-4 breast development and they were a bit uneven in size so I figured they weren't done growing. Sure enough, at 18-19 they went up to 30E. They haven't shown much change in this past year but they still have a bit of that stage-4 look to them and some asymmetry. All the women in my family have very large breasts and several, including my mom, have even needed reductions, so I'm kinda (stupidly) hoping that they're going to get a few cup sizes bigger.

Since my development started late, it makes sense that it would end later, right? Does anyone have any input? They're appearance makes it seem like development isn't over, but it's so hard to tell.

Welcome to the ehealthforum and I am glad to help you out.

Breast size can be increased by estrogen or progesterone pills. However, it is not safe to use estrogen in this way because when breast cells are stimulated to grow, they are more likely to turn cancerous.

Breast augmentation is the only reliable method that is available. In this a breast implant which is a prosthesis is used to enlarge the size of the breasts. Please consult a plastic surgeon for that.

I sincerely hope that helps. Take care.
