I'm 16 yrs old. What Breast development stage am I in?

Keep in mind that your breasts continue to develop throughout your life, and you may experience noticeable changes until about 19-20 years old. Breast development is different for each female, so it would be difficult to say at what stage you are.

You are too young to consider breast implants.  Your breasts are likely to continue to change over the next few years.  You should reassess the situation after a few more years.

It's impossible to say at age 16 whether your breast development is complete or not. This is genetically determined.

Its
hard to state “what stage” of development you have reached, but it is safe to
assume that there my be further enlargement of your breast until the age of 18-19.
Because the breasts are changing, plastic surgeons do not ordinarily recommend
surgery (such as breast implants) in patients younger than 20-21. Be patient.

Thank you for your question.  Most patients find that breast growth continues until 18-21 years of age.  However breast shape Is often congenitally determined thus you should discuss this with your mother to see if she has similarly shaped breasts.Because your breasts will continue to grow you should wait until you're 21 before considering any type of surgical intervention.  For narrow breasts, angular breasts, or unusual shaped breasts, breast augmentation is often a very successful method for improving the shape and creating a round breast.It would not be a bad idea at this stage to go with your mother to see a plastic surgeon for an evaluation, diagnosis and recommendation for future treatments when you are 21.

Thanks for the question. One way to know is at what age your Mother (and sisters if you have them) stopped developing. Many young women are done with breast development by 16-17 but that is not universally true.
