What is wrong with my left breast? it has no hormones at all like the right one does. and the right one is bigger and grow w/o the left one growing!?!

Natural variations: One breast is naturally larger that the other and the degree to which one is different than the other varies greatly from woman to woman. The differences in size are more pronounced in younger women going through puberty, as she matures. Breasts continue growing well into the early twenties. I would see my GYN and have her/him examine you and discuss with you the likely normal variation in size.
