Signs & Symptoms of Breast Development
Females develop breasts as an important part of their reproduction system. Development actually begins in the fetal stages, and continues throughout a female's lifetime. For young girls, outward breast development is an important, emotional time. Final changes occur at menopause, signifying the end of the reproductive cycle.
