I know this has probably been asked before a bunch of times, but I haven't seen related topics, so here we go.
My left breast has taken on this growth thing much more enthusiastically than the right one. Now, I know this is completely normal and common, but I was wondering if there's anything I can do to help them sync up better? I've been massaging the lagging one, which I've heard might help, but I don't know if that's that true either.
I'm also wondering, how likely it is that they'll catch up to each other at some point? Again, I know it's common and normal to have some size variance from one side to the other, but have you found that they'll get their act together a bit more after prolonged time on HRT?
I can't help much because I am not on HRT, but I can tell that I have heard from cis females that they also have asymetric breast growth and that one ends up slightly bigger than the other, so it sure is common and doesn't mean anything is wrong with you! If you're very worried, maybe talk to your endo? best wishes, xxx
Asymmetric breast growth is quite common even in cis-women, so unless one is drastically smaller I wouldn't sweat it. There are extreme but rare cases where one breast fails to grow much at all with respect to its partner breast and the owner of said breasts either has to wear a breastform or an implant to balance the pair out.
