Growth is finished at an early age but changes continue throughout your life. Weight loss/gain, genetics, pregnancy, and age can all affect your breasts over a lifetime.

There is no answer that will cover an individual woman. Variances are common, but on average, breast growth is complete by late teens to early twenties. Breast changes do continue with pregnancy, and weight gain. 

Thank you for your question, best wishes.

Usually the female breasts complete their development 3 to 4 years after the first menstrual period; but structural changes will keep happening during the entire life (pregnancy, breastfeeding, menopause).

Breast Growth

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
In general, breast development/growth ceases between ages 17-21 years.  A woman's age and breast growth is taken into consideration by plastic surgeons when discussing certain breast procedures with patients, especially younger patients.  That being said, breast size and shape never stop evolving during a woman's life and are affected by such things as pregnancy, breast feeding, weight gain/loss, and menopause.  These things will also affect a woman's breasts after having surgery such as breast augmentation, reduction, or lift.

When are breasts fully developed?

That is a good question.  It varies from person to person, but is complete by 18 or 19 in most people.  Since it is individualized, you should wait to have any surgery until you feel like your breasts have been unchanged for at least 6 months.  Good luck!

Breast development usually is complete by 18 - 22 years in most women. However, breast shape & size never stop evolving during a woman's life. They are affected by various milestones in a woman life such as pregnancy, breast feeding and menopause. Weight gain & weight loss can also impact the breast size. All these events can alter the breast shape & size following a breast augmentation or breast lift too.

At what age do your breasts stop developing.

This is a great question and really has a few different answers. Most women start to notice an enlargement of their breast tissue around puberty. Puberty in women typically happens before most males and occurs anywhere from 9-16 years old. If a women has not noticed much change in her breasts after the age of 18, then they have likely finished "developing". Breasts can also change in size according to weight gain and loss. In addition, when a women becomes pregnant, the breast tissue is stimulated to "grow" in order to prepare for lactation.

Breast Development and Age

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Breast development begins in adolescence and in puberty the ovaries begin to secrete estrogen, causing breast enlargement through both breast tissue growth and fat accumulation. The rate and timing and amount of breast growth varies greatly up through the fully mature breast.

Most commonly breast development has slowed or neared completion by age 18 to 20, but the breast continues to change throughout life through the influences of time, pregnancy and nursing and weight changes. 

For cosmetic breast surgery, a patient must be 18 years of age, and I recommend waiting until breast development has completed (size has remained unchanged for 6-12 months). Some women are candidates for breast symmetry procedures for very asymmetric breasts at an earlier age. If you have questions about breast development and breast surgery, seek out an experienced surgeon for a consultation.

Hope this helps.

Breasts Continue to Change Throughout a Woman's Life

This is a great question. Although the FDA issues standard guidelines for breast augmentation at age 18, actual breast development is very variable from woman to woman. I explain more in the video.

Do the breast stop developing?

The breast actually never stop developing. Rather they continue to undergo changes throughout a woman's life.  There is a natural process of breast growth that begins around puberty and continues late into the teenage years and early twenties.  Most doctors would agree that what you see is what you get by the time you are in your early twenties.  The breast however continue to evolve throughout ones life.  This is mostly determined by the hormone levels in the body.  Certainly pregnancy and breast feeding can significantly affect the breasts.  In the later stages of life the breasts will gradually become smaller and the breast tissue is replaced by fat.
