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.
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.
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).
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.
At What Age Do Your Breast Stop Developing?
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.
Breasts usually stop developing when a woman is a litter younger than eighteen. However, breasts can continue to change in shape and size throughout life due to pregnancy and changes in weight and age.
Breast Development Doesn't Really Stop
Technically, early breast development (growth of the gland) is mostly completed in the early 20's for most women - and there is a lot of variation. For most women trying to decide timing of breast augmentation, the early 20's is a good guideline for gauging the desired breast implant size.
Importantly, the breast does continue to change throughout most women's lives: hormone changes, pregnancies, weight gain or weight loss, heredity and aging all affect the size and shape of a woman's breasts.
I'm assuming the real question here is "at what age will my breast growth stop?" Breast growth/development usually maximizes by about 16 years old. Obviously, everyone is different and breasts change with overall body weight, pregnancies and breast feeding. If you're 18 years old and are unhappy with your breast size, I would recommend seeing a plastic surgeon for a consultation.
At what age do your breasts stop developing?
Formal breast development begins at thelarche, which starts in half of women at around 8 years old. Breast tissue actually can develop at several points throughout the life cycle. You can actually have premature breast development as a newborn from residual estrogen from the mother. This usually resolves around 2 years of age.
Classically, breast development from puberty "ends" around 16-21 years of age. However, women in menopause can sometimes develop additional breast tissue. This is usually adipose tissue ("fatty" breast development) but is often a reason that women seek breast reduction/ and/or removal of breast implants.

the shape and volume can still change depending on body habits and pregnancy.
