How Does A Breast Grow

Published: May 14, 2012
Dear TeenHealthFX,
I've got a question regarding breast growth. When does the breast stop growing in size? How does a breast grow? I'm a 21-year-old Asian girl and I'd appreciate your help. Thanks.

Dear How Does A Breast Grow,


Breast growth sometimes is described within 5 stages:

  • Stage 1- Consists of a small-elevated nipple with no significant underlying breast tissue.
  • Stage 2- Is referred too as "budding." This happens when there is an elevation of the breast, the areolas (darker area around nipple) enlarge and the nipples swell and become tender. The areola begins to darken in color. The milk ducts give rise to milk glands that begin to grow.
  • Stage 3- There is further enlargement and elevation of the breast and areola.
  • Stage 4- The breasts may change only in contour (shape) rather than size, and the nipple protrudes.
  • Stage 5- Breast growth is completed.

You should know that these stages were based on the study of white English girls. Recent studies have shown that some ethnic groups (African American girls) tended to advance more quickly.

Also, it is important to note that breast size and breast development are not always related.  Breast size can be related to a persons weight.

Since most women develop at different rates it is hard to give an exact time when the breasts have reached their maximum growth. A rough estimate would be that most breasts continue to grow for several years after your first period.
