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

Breast development usually occurs through the teenaged years, and physiologic development ends usually by 18 years of age. Thereafter, breasts continue to evolve and change, and this is affected by weight loss or gain, pregnancy, and aging overall.

Every Woman Is Different

Thanks for your question. As with many things related to the body, there are few absolutes when it comes to breast development. Typically, the breasts stop growing after puberty ends, which can vary but often occurs between the ages of 15 and 18. Of course, just because puberty is over doesn't mean the breasts will never change again. Weight gain or loss, hormonal fluctuations, and pregnancy can all affect the size and the shape of the breasts over the course of a woman's life. So although the breasts may stop growing, they continue changing throughout a lifetime.

What age do breast stop developing? Connecticut

Breast continue to change throughout your lifetime. Breast development usually stops shortly after puberty, between age 16-20. However, breast development is also related to your weight gain and loss and your pregnancy history. Later in life breast change is associated with hormone deficiencies cause breasts to change in a way usually associated with atrophy and sagging.

They Stop Developing, But They Don't Stop Changing

Good question. Breasts usually stop developing by the age of 18, but that doesn't mean that they stop changing. Weight fluctuations have a significant effect on breast size and shape, as well as hormones and their changes throughout life. Pregnancies can change the shape and sizes of the breasts, as well. That means that differently sized implants may be appropriate at various times in a woman's life, depending on her goals and desires. It is important to be evaluated by a board-certified plastic surgeon who understands the goals of the patient and can match them to a range of implants that will provide the desired results. Thanks for your question.

Even after puberty, your breasts will change over your lifetime.

In most cases, breast development begins during puberty (in women, average puberty onset can occur anywhere between the ages of 8 and 13 and lasts approximately 2 years) and ends once your body settles into adulthood, somewhere around your early 20s. Even once your breasts have finished their initial growth during adolescence, there are many other changes that can happen during your lifetime that can further affect breast size and shape, like weight fluctuations, pregnancy, nursing and just growing older. Implants can be considered after the age of 18, but some women choose to wait a couple more years to give their bodies a chance to catch up and others put breast augmentation off until after completing their families.

Breast Development

Breast development is unique to each girl/woman and like many things influenced by genetics and environment. Breast development is one of the female secondary sex characteristics that are a manifestation of increased estrogen and so breast development proceeds along with other secondary sex characteristics (body hair, fat distribution, hip/pelvis changes, etc). For most American girls and young women breast development is complete by the late teens. If one's breasts have be stable for several months and the other secondary sex characteristics are mature then it is reasonable to assume that breast development is complete.

At What Age Do Breasts Stop Developing?

The age at which breasts stop developing depends primarily on genetics, but may be impacted by environmental influences. The vast majority of women finish breast development around age 18, although according to reports, some may develop into their early 20s.

If breast growth has plateaued for a year, it's unlikely that the breasts will continue to develop after that. However, breast size can increase throughout a woman's life due to weight gain or hormonal influences, including birth control pills, pregnancy, and breast feeding. Breasts can also lose volume after pregnancy, after weaning one's baby, and from weight loss,.

Breasts change throughout a woman's life. Some hope for an increase in size throughout their teens and into their 20s, and they never get it. (That's when they seek help from a plastic surgeon.)
