If you do them properly they will heal completely if you don't wear jewelry in them anymore. The reason most people with big ones have cat-butts or have to get they surgically fixed is because they stretch way too fast and have blowouts. A blowout is when you stretch the fistula (the flesh on the inside of the piercing) to breaking point it then heals with scar tissue. Time after time, more scar tissue builds up and your ear loses elasticity.
If you stretch slowly over a long period of time you wont cause a blowout and wont have scar tissue. My ears were close to an inch at one point, now I couldn't put girl earings in my ears without pushing.
