Is a Breast Reduction Safe at Age 15?

It is generally safe.  Your parents will have to sign your consents to have surgery. 

It is important that your weight and growth have stabilized prior to undergoing the procedure otherwise you may be subject to ongoing breast enlargement.

Reduction are safe but like any surgery, a proper medical and physical exam must be done. Reductions can be done at 15 with parental consent, and the proper medical clearances. Insurance coverage is a hit or miss depending on the carrier.  Usually having symptoms related to breast size is necessary for insurance coverage. Getting it covered though is very difficult. Insurance companies wont tell anyone how much tissue needs to be removed to qualify for coverage. Then if the surgeon is 1gram off they deny coverage after the fact. Insurance companies make money by denying coverage. For that reason most plastic surgeon will likely ask for payment up front.  Breast reductions are the most gratifying operations because years of neck, back and shoulder pain are gone within days.  The final size result depends on your starting size. If you start larger then you will likely end larger. It is not possible to choose a size with any real accuracy. The main reason is that the procedure removes breast tissue but leaves enough tissue to preserve the blood supply to the nipple and areola. Thus more tissue needs to be left behind to ensure nipple viability. The nipple and areola is constantly being accessed during the operation.
