How do girls under 18 get breast implants?

Question: 
I recently saw something on the TV where high school girls were getting breast implants. I thought you had to be 18. How does this happen?

Answer: 
The FDA mandates that patients be 18 prior to breast augmentation; however, there may be some scenarios where there is severe asymmetry or developmental issues where younger women might be having breast augmentation surgery but these are few and far between.
