At What Age Do Your Breast Stop Developing?

Breast Growth

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.

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 augmentation

In breast augmentation I have chosen to spend time reviewing photographs with patients to fully understand their expectation of size and shape. Many times this simply raises more questions. I will make measurements and use the implant guides to allow the patient to understand exactly the sizes that are reasonable for their body type and measurements.

When do your breasts stop growing?

For most women, your breasts will start growing prior to the start of your menstrual cycle beginning and end somewhere between the age of 18 and 21 years old. This can vary slightly from person to person and the breasts do continue to have other changes in shape and size (weight gain or loss, pregnancy, etc) for the rest of your life.

Normal breast development

Normal female breast development occurs in distinct stages throughout a woman's life. For most women breast development starts in their early teen years and stops usually by there early 20's. Breast size and shape is further influenced by pregnancy, breast feeding after child birth  and later menopause. Some women's breast can also change significantly during their monthly period.

Breast development

Breast development usually stops at the end of puberty.This is typically age 16-18 years old. But since every woman is different, these numbers can vary slightly by a few years.

Age breasts stop developing

Every individual is unique in their won growth pattern.  However, most women's breasts stop developing in their late teens.  Changes in breast size and shape continue to occur throughout life, and are the result of weight changes, aging of the skin and support ligaments, pregnancy and weight changes.

At What Age Do Your Breasts Stop Developing?

Breast development occurs throughout puberty. The breast has usually completed its development by the age of 18. Although breasts finish developing at age 18 they continue to change throughout someone's life. This can be related to fluctuations in hormones or the use of birth control, changes in weight, menopause, or pregnancy and breast-feeding.

When do breasts stop growing?

In general, I tell my patients that breast development occurs through age 18.  That being said, your breasts will continue to change throughout your life, depending upon hormone fluctuations, pregnancy, and weight gain or loss.
