Breast size


Hello doctor, I am currently in my first year of high school, with a height of 165 cm and a weight of 47 kg.
I have had my period for a year, I have pubic hair, and my breast size is already 36E.
Is it still possible for me to continue growing?

Dr. Wu Jianting reply Breast and Thyroid


The breasts are theoretically still in the growth and development phase until the twenties, and the size they reach depends on the individual.
Thank you for your question.

Breast development is a complex process influenced by various factors, including genetics, hormonal changes, and overall body composition. In general, breast tissue continues to grow and develop throughout puberty and can continue to change into a person's early twenties. For many individuals, breast size can fluctuate due to hormonal changes associated with the menstrual cycle, pregnancy, and weight changes.

In your case, since you are currently in high school and have already started menstruating, it is possible that your breasts may continue to grow, although the extent of this growth can vary significantly from person to person. The average age for breast development to complete is around 18 to 20 years, but some individuals may experience changes even into their early twenties. Factors such as genetics play a significant role in determining the final breast size, so it is difficult to predict exactly how much more growth you might experience.

Regarding your current breast size of 36E, it is important to note that breast size can be influenced by body weight and fat distribution. If you gain or lose weight, your breast size may also change. Additionally, hormonal factors, such as those related to menstrual cycles, can cause temporary swelling or changes in breast size, which may give the impression of growth.

If you are concerned about your breast development or have specific goals regarding your breast size, it may be beneficial to consult with a healthcare professional, such as an endocrinologist or a plastic surgeon specializing in breast health. They can provide personalized advice based on your individual circumstances and help you understand the factors that may influence your breast development.

In summary, while it is possible for breast size to continue to grow after menstruation begins, the extent of growth varies among individuals. Factors such as genetics, hormonal changes, and body composition all play a role in determining breast size. If you have concerns or questions about your breast development, seeking professional medical advice is always a good step.
