Im sorry where does it say they can re-grow limbs , im serious ive never seen this before im interested.

Clones were given pieces of their fallen brethren if injured badly enough.

I’m pretty sure most people just prefer the prosthetic. Either that, or it’s too expensive or there could be potential medical concerns.

^yeah it's probably to expensive, both Anakin and Luke weren't rich.

Only recently have humans began to regrow their organs. It's very expensive though, and still unknown if it's going to be feasible.

Main reason why, is if you lose your arm, would you want another arm that you could lose? Why not take a prosthetic, in a galaxy where apparently they function very well and eliminate all pain.

Boba Fett had a cloned leg grown for him and reattached. Of course by this point he was exceedingly wealthy.

The Vong introduced the galaxy to the idea of grafting foreign body parts in place of lost ones, and the Killiks grafted their own bug parts onto the severely injured Sith Lomi Plo and Welk. Lomi ended up a bug headed four armed monstrosity.
