Is there any way for a 12 year old to getr smaller chest without surgery?

It is not advisable for a 12 year old to try to reduce the size of their chest without proper medical advice and supervision. Changes in chest size are usually related to natural growth and development, and attempting to alter this through non-surgical means may not be effective or safe. Instead, it is recommended to focus on healthy lifestyle choices, such as balanced diet and exercise, to support overall well-being and development. If there are any specific concerns or issues related to chest size, it is best to consult with a healthcare professional for personalized guidance and support.
