The basics about BREASTS:
STAGES OF DEVELOPMENT

Stage 1– Childhood
Breasts are flat to chest with a  
raised nipple and areola.

Stage 2 - Breast buds (Ages 9 -11)
A breast bump develops under
each nipple and some         
tenderness may occur.

Stage 3 - Development Continues
(Ages 10 – 13)
Breasts get larger pointy. Adult in
shape but smaller.

Stage 4 - Nipple/Areola Mound
(Ages 12 – 14)
Some girls skip this stage and
some never develop past this         
stage.  The breast is often cone
shaped.

Stage 5- Adult          
Breasts are fully developed and  
have a round, full shape.
Each breast consists of a mound of fat
tissue containing milk glands and ducts.


The nipple is located in the center of
the breast (it may be raised or  slightly
inverted).

The nipple is surrounded by the areola
(which may be any color from pink to
dark brown)
