Will going into gymnastics affect my breast development?

Or opposite: Breast development is related to the interplay of genetics, hormonal factors & general health.The dietary discipline required for the nimble frame of a gymnast is usually quite healthy. Low body fat levels sometimes delay menses but for most will not affect eventual breast size, the opposite may be true.Those that are destined to be top heavy may find it harder to remain competative.

Depends: If you look at olympic level gymnast it is obvious there is a delay in development. There is a retrospective review ( not the best study method) that shows for those in the gym more than 15 hours per week there is an increase risk of delayed puberty. This is related to hormonal issues. Once you discontinue gymastics/decrease time in gym/ gain weight your breast development should resume.
