plastic surgeons usually perform procedures that are not medically necessary, but only improve appearance to boost patient's self-esteem (boob job, facelift, butt job, etc)

You moved the goalpost. You stipulated high risk in the comment I was replying to. And who cares what plastic surgeons “usually” do? A doctor who gives boob jobs to women who are already “normal” (not to reconstruct after a mastectomy, for example) is a scourge who is exploiting society’s bad attitudes and exploiting his patients. Not a good doctor. Or are you suggesting that if a lot of people do it, that makes it good?
