At What Age Do Your Breast Stop Developing?

Doctor Answers (22)

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.

Breast Development

Excellent Question!  Most women have completed breast development by the age of 18.  I feel comfortable operating on women for cosmetic and reconstruction (ex: restricted breast deformities) reasons when they turn 18 years old.

Breasts continue to change over a woman's lifetime.  Weight gain/weight loss, skin elasticity, and hormonal changes all contribute to breasts shape and size.

Breasts never fully finish developing.

Full breast development is by and large attained between the ages of 18 and 22 years of age. On the other hand, its imperative to recall that breasts never finish evolving. Breast feeding, pregnancy, changes in weight and lifestyle all effect breast wellbeing throughout the span of time.

Developed by about 18, but never done changing

Most women's breast stop developing by age 18, but no woman's breasts are ever done changing. Breast size and shape changes with weight fluctuations, pregnancy, breast feeding, hormone changes, and aging.

Every woman has a course and timeline for development that is all her own. If you have questions about your breasts find a doctor you are comfortable asking - it is perfectly normal to wonder about these things - your doctor can give you a better idea of when your breast development will be complete.

Breast development stages

Breast development occurs in stages, and there is a lot of variety between women.  Many girls start developing raised nipples and a breast bud around age 7-11.  Increasing breast fullness and changes in shape continue on for many years - usually stabilizing around age 16-18.   It is important to note that some women don't stop developing until after 18 years of age -  everyone is an individual.   Throughout life, breasts continue to go through size and shape changes from weight gain or loss, hormonal imbalances, pregnancy, lactation, and the aging process.
