Answer:
No. Plastic surgery is also called cosmetic surgery. Basically, it's surgery that specializes in the reconstruction, altering, or modification of the body. For example: breast implants, chin implants, breast reductions, face lifts, rhinoplasty procedures, or nose jobs, etc..
The word plastic comes from the Greek plastikos which means to sculpt or to form, which is what the plastic surgeon does with the human body. Cosmetic or aesthetic surgery is one branch of plastic surgery; reconstructive surgery is the other.
