How does Tanner stage V for females describe the size of the breast?

Tanner stage V for females is characterized by the final development of breast tissue, which indicates that the breasts have reached their adult size. This stage signifies the culmination of the pubertal changes that began in earlier stages, where the breasts progressively developed and enlarged. By stage V, the breast contours have matured, and both the glandular and adipose (fat) tissues have fully formed, leading to the establishment of the final adult breast size.

Understanding Tanner stages is crucial for assessing normal puberty progression, as each stage describes distinct physical changes. In Tanner stage V, the development of the breast is complete, distinguishing it from earlier stages where the breast size was still in a transition phase. Thus, this stage emphasizes that the breasts have fully matured and reflect the typical adult breast anatomy and proportion.
