Because Miami is this country’s plastic surgery capital. Like Cali, Colombia, Santo Domingo, DR etc...Too many surgeons concentrated in an area where enhancements are encouraged and lax regulation around who can perform the surgery and no malpractice insurance. A lot of surgeons there are not board certified and a lot of those surgeons work in high volume surgery centers usually aimed toward working class women who can’t afford the $10-15k private practice charges.
Do your research, go private practice make sure the surgeon specializes in breasts or whatever procedure you’re looking at and don’t skimp on the price or quality of care. Make sure your surgeon is Board Certified in Plastic surgery, NOT cosmetic surgery or general surgery.
The good surgeons in Miami are still $8k-12k for a breast augmentation.
