At What Age Do Your Breast Stop Developing?

When do your breasts stop developing

+2
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.

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.

At What Age Do Your Breast Stop Developing?

Thank you for the question!  Your breasts are in stages of evolution throughout your life.  When hormones like estrogen and progesterone fluctuate, your breasts can change composition from densely glandular to a fatty composition.  Gravity also stretches breast tissue and ligaments to a lower position on your body when standing.  Breast reduction, augmentation, and lifts are frequent procedures performed to help achieve ideal breasts for women depending on their preference and medical needs.  I hope this answers your question!

Although breast growth varies from patient to patient, it generally stops between 18 and 22 years of age.
Your breasts will continue to change throughout your life, pregnancy, nursing, weight gain, other hormonal changes, and aging will affect the size and shape of your breasts.

Breast Development and Age

+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.
