At What Age Do Your Breast Stop Developing?

Doctor Answers (31)

When do your breasts stop developing

The truth is that breasts are continously changing organs.  There are women who were A cups prior to having kids and are now D cups and vs versa.  As for pubety related development, if you haven't increased size by 17-18 then you are unlikely to suddenly develop breasts.  On the other hand if your breasts are still changing then there is no exact time they will stop. 

Hope that 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.

Breast Development

Breast development typically completes itself shortly after puberty in girls, about the age of 15 or 18 years. Several factors can affect breast development and size both during puberty and throughout life. Some of these are genetic while others are not. Weight has a significant impact on breast size as does other factors that influence hormones such as pregnancy, breast feeding and menopause. How the breasts respond to the female hormones varies for each individual and can result in either a decrease or increase in breast size as well as change in breast shape. Breast shape also changes over time with changes in breast tissue support and skin elasticity. Breast enhancement, therefore, must be tailored to the individual. Seeking a board certified plastic surgeon trained in the nuance of breast surgery is important in getting the best results.

Breast Development and Age

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.

Breast development

Most girls breasts have stopped developing around 15-16 years of age, but a few women will continue to develop up to age 21.  Pregnancy, nursing,  weight gain, other hormonal changes, and aging will affect the size and shape of your breasts.  You might consider asking the older women in your family about when they stopped developing.  Genetics do play a strong role in the size of your breasts.,

Breast Development

Your breasts will continue to change throughout your lifetime. The volume of your breast usually achieves its endpoint by 16 to 18 years old. However, your development is also depending upon your weight gain and loss and your pregnancy history. As you get much older your hormone deficiencies cause your breasts to change in a way usually associated with atrophy and sagging. Because of this, making choices for your breast enhancement is something that is best done with a board certified plastic surgeon. I can help you discuss your family history and your breast augmentation goals that you have at the time of your consultation.

Your Breasts Continue to Change Throughout Your Life

In general, female breasts stop developing at around 18 or 19 years old. This is when a primary level of maturity is achieved, however further changes occur with pregnancy and lactation (the production of breast milk). Your breasts will continue to change throughout your life, as the signs of aging become more apparent. For example, your breasts may begin to droop as supportive tissues weaken, or grow larger when you gain weight.
