I agree with you, and in fact, it's a pretty hard surgery with several serious consequences, so it's worth thinking a few times about the need for it. My friend, after this surgery, disappeared from work for several months because of the development of complications. So make use of expert-written resources before you believe a surgeon's reviews on the Internet. Medical interventions are essential and complex and need to be rational. Otherwise, it seems that such manipulations do not make sense.
