Almost always a better idea to avoid anything preemptive. You never really know that you’re going to need it done anyway (see bbleeker’s comment), even if you might need it done in 5 or 10 years you might be dead of other things by that time anyway, and medical techniques improve over time (so surgery in 5 or 10 years is likely enough to be safer and less painful than surgery now.)
