Thank you for the question.
It sounds like you are dealing with juvenile breast hypertrophy; in other words, the breasts are too large for the frame causing both physical and psychological distress.
As you think about breast reduction surgery make sure you do your homework and understand the potential risks and complications associated with the procedure. Unsatisfactory scarring is one of the potential complications. Make sure you also understands that further surgery may be necessary in the future (for example if the breasts were to grow in size again).
On the other hand, breast reduction surgery is one of the most patient pleasing operations we perform and I think that for the right teenager (enough symptoms) it may be an excellent option (regardless of the age).
Sometimes breast reduction surgery is covered through health insurance. The best way to obtain insurance coverage for breast reduction surgery involves some “hoops” to jump through. The more documentation you have (for example, from your primary care doctor, physical therapist, chiropractor etc.) the better when it comes to obtaining insurance “authorization” for the procedure.
This documentation and letter/pictures from your plastic surgeon will help you obtain authorization.
Make sure you're working with a well-trained/experienced board-certified plastic surgeon.
Ask your mother to join you in the consultation.
I hope this helps.
