Can a 15 year old get a breast lift?

YES! with parental consent ONLY. Best to seek in person consultations with boarded private practice PS in MIAMI. 

If you are fifteen and have very large breasts, breast
reduction may be an appropriate procedure. It's important to be sure
expectations are realistic and you have an understanding of the commitment
needed for the healing process. Make sure that you understand the nature of
your surgery, the recovery process, and that you feel comfortable and
emotionally ready to make these changes to your body.
To perk up a drooping breast, your surgeon will remove
excess skin, reposition the nipple, and redrape and tighten the remaining skin
to support the breast. The areola may also be reduced in size. A mastopexy
(breast lift) raises droopy breasts from one to several inches and excess skin
is removed. I commonly use a minimal incision technique (Le Jour), eliminating
the need for large scars while providing a pleasing breast contour and shape that
is proportionate to the patient’s body. If you're sagging or asymmetrical, and
are looking for perkiness, you'll need a lift. The great thing about these
techniques is that they can now be down with minimal scarring and performed as
an outpatient procedure without the need for general anesthesia.
