In Stage 3 of the Tanner scale, breast development is characterized by breast enlargement, and this enlargement occurs without the separation of the areola from the breast contour. This stage represents a significant progression in breast development, where the overall size of the breast increases, but the areola remains connected to the breast instead of forming a two-part structure.

Observing breast development through the Tanner stages is crucial for understanding normal puberty-related changes in females. In Stage 3, the breast tissue has evolved beyond early bud formation into a more developed form, indicating progress toward full maturity.

The other options represent changes in different Tanner stages. For instance, the separation of the areola from the breast contour happens in Stage 4, while breast buds are associated with Stage 2. The projection of the areola and papilla occurs later as part of the final stages of breast development. Therefore, the distinctive feature of Stage 3 is that the breast continues to enlarge while the areola remains integrated with the breast base, reflecting a transitional developmental phase without the distinct separation.
